Version 2.10
---------
* Add --ssh-port option.
Version 2.9
---------
* Fix: backup with compression enabled fails: unsupported operand type(s) for
+: 'int' and 'dict' (#177)
Version 2.8
---------
* Add packages compatible to fedora 39 to package build (#174)
* Show total saved disk size in human readable output (#173)
Version 2.7
---------
* Update README
* End backup with warning if software emulated TPM device is attached
(#169)
* Detect remote connection based on libvirt URI, checking hostnames could lead
to situation where local backup is detected as remote backup (#170)
Version 2.6
---------
* Fix IndexError exception if auth file is used in qemu uri (#167)
* Credential function for libvirt must return integer: fix NoneType
exception if actual libvirt authentication is required.
* Simplify libvirt authentication code: attempt to use SASL based mechanism
only if --user and --password options are set.
* If authentication fails because of missing SASL mechs, ajdust error
message, provide hint for --user and --password options.
* Update README regards OVIRT/RHEV/OLVM (no mechanism available: No worthy
mechs found)
Version 2.5
---------
* Move some log messages from info to debug loglevel
* Log information about libnbd version only once
* Catch command not found error during remote backup if qemu-img
is missing: change loglevel to warning.
* Catch command not found error during remote restore: fail with
proper error message.
* If no qcow image info has been created during backup, issue warning
during restore that default options are used.
* Update README: add note about scratch files.
* Do not attempt to freeze filesystems if virtual machine is in paused state
(#166)
Version 2.4
---------
* Update RADME
* Add qemu-utils to package dependencies: if installed on a system without
libvirt/qemu, backup fails because of missing qemu-img executable.
* Add openssh-client to package dependencies: required for remote libvirtd
connection.
* Catch exception if executed commands such as qemu-img are missing on
system.
* Code cleanup
Version 2.3
---------
* Update README
* Add option -S (--start-domain): if specified and virtual domain is offline
during backup, domain will be started in pause mode, allowing to execute
full/diff/inc backups. Domain is destroyed as soon as operation finished
by using libvirt's AUTODESTROY flag. (#164)
* Move code for preflight tests to separate module.
Version 2.2
---------
* Fix Progressbar during restore: wrong values used. (#160)
* Catch exception if during restore connection to NBD server fails (#163)
* Provide better info message what NBD connection is waiting for.
* Call flush() on NBD connection during restore: restore of domains
with multiple disks could fail with NbdConnectionTimeout due to race
condition (#163)
* Pass pidFile to qemu-nbd process for local NBD server during restore,
report PID of forked process instead of parent.
Version 2.1
---------
* Fix Progressbar: Since change for issue #133 the Progressbar was
updated with wrong values and as result progressed too fast for the amount of
data actually written. (#160)
Version 2.0
---------
* Update README
* Fail early during incremental or differential backup if no
full backup is found in target directory.
Version 1.9.55
---------
* virtnbdmap: pass listen address argument to qemu-nbd command.
Version 1.9.54
---------
* Exit with error if both compress option and raw output format
is specified: options are mutually exclusive.
* Update progressbar during chunked data read/write. If big portions
of the disk are backed up, it would appear as if no progress is made
(#133)
* If an active remote backup is aborted (ctrl+c), stopping the libvirt backup job
failed because the signal is sent to the used ssh connection, too. Now the
signal handler attempts to re establish the connection to the remote system
in order to correctly stop the backup operation.
* Add close() function to libvirt client class: disconnect libvirt after
backup has finished.
* virtnbdmap: code reorg.
Version 1.9.53
---------
* Move checksum related code to own function
* Set a shorter thread name, makes logging messages are easier to read.
* Add opensuse/leap:15.5 to release build.
Version 1.9.52
---------
* Code cleanup
* Build release packages using github actions.
Version 1.9.51
---------
* Slight change in log message wording.
* virtnbdrestore: if starting NBD service on remote system fails, catch
exceptions accordingly.
* virtnbdrestore: if --nbd-ip parameter is set, pass -b option to qemu-nbd
command so the NDB service binds to specified IP address.
* virtnbdrestore: Set SSH session mode to UPLOAD, otherwise uploading
files such as UEFI images and vm config fails.
* virtnbdrestore: Catch exception if connection to libvirt fails
* virtnbdrestore: Create target directory on remote system only if it does
not exist, Thanks @draggeta
* CI: enhance remote backup check: test if UEFI loader files are copied
correctly during remote backup.
Version 1.9.50
---------
* Add openssh-client to docker image required for remote backup
functionality (#151)
* Check if specified ip address in `--nbd-ip` parameter is an
ipv6 address and if so, use ipv6 ip notation for NBD client
connection (#150)
* Fix NBD connection timeout: current implementation only waited
until NBD server on socket was reachable. Now it also attempts to
retry connection for remote TCP NBD servers (#150)
* Fix exception in ssh client during raise
Version 1.9.49
---------
* Logging: Use blue color definition instead of light-blue which might not be
supported by all colorlog versions (#148)
Version 1.9.48
---------
* Rework some error messages / exception handling.
Version 1.9.47
---------
* Remote backup: catch more exceptions accordingly, provide better
error message if ssh connection fails.
Version 1.9.46
---------
* Update package dependencies in docker file.
* Spelling fixes
Version 1.9.45
---------
* virtnbdbackup: Add more info output during checkpoint handling, move
error message.
* Add colorful log messages so warnings and and errors are easier to spot:
can be disabled using the --nocolor option.
Version 1.9.44
---------
* virtnbdbackup: disable progressbar if quiet option is enabled.
Version 1.9.43
---------
* virtnbdbackup: add --quiet option: disable log output to stderr,
log into logfile only. (#137)
Version 1.9.42
---------
* virtnbdbackup: skip checksum output if backup is redirected to stdout
Version 1.9.41
---------
* virtnbdrestore: add Option -B to allow changing default buffer size
during verify to speed up process.
Version 1.9.40
---------
* Update README
* New feature: compute adler32 checksum for written data and add
verify option to virtnbdrestore, so its possible to check for corrupt
backups without having to restore.
Version 1.9.39
---------
* Update README
Version 1.9.38
---------
* Release packages compatible with RHEL9 (#130)
+ add required vagrant file
+ adjust requirements during package build
+ put dist files into separate directories
Version 1.9.37
---------
* Update README: add example how to convert qcow images to the required
format to support all backup features.
Version 1.9.36
---------
* Fail with better understandable error message if libvirt version requires
the virtual machine configuration to be adjusted for backup to work.
Version 1.9.35
---------
* Fix some pylint warnings, add ignores.
Version 1.9.34
---------
* Update README
Version 1.9.33
---------
* Update README
Version 1.9.32
---------
* Fix TypeError during backup of transient virtual machines: do not pass
flags to checkpointCreateXML as list. (#122)
* Add simple test for transient virtual machine handling.
Version 1.9.31
---------
* setup.cfg: fix obsolete description-file warning

+ fail correctly if backup to stdout is attempted
+ override --raw option during attempted incremental or differential backup:
backup modes will only be attempted for disks supporting the required
features.
* If no disks suitable for backup are detected or backup fails, save at least
virtual machine configuration and related kernel/uefi files (#93)
Version 1.9.12

to have saner logging information.
Version 1.9.11
---------
* Log traceback for unknown exceptions for easier analysis of issues. (#92)

---------
* Update README
* Code cleanup, use shorter class names, change some error handling.
* virtnbdrestore: in case option -D is passed, set option to adjust virtual
machine config automatically.
* virtnbdbackup: amount of ports used for offline backup depends on how many
workers are used, not how much disks are attached, log correct port range use
during offline backup.
Development:
* Github workflow now saves all files created by testsuite for better
analysis, extend some testcases.
Version 1.9.6
---------
* virtnbdrestore: add detection for disks with volume notation, reset
type to file during restore so virtual machine config is adjusted to
new restore paths. (#81)

Version 1.9.4
---------
* Code cleanup: more type annotations, correctly catch ssh exceptions.
* Better logging information in case of remote backup
* Remote backup of offline virtual machines with multiple disks may fail:
(#82) port used by remote NBD Service must be unique. Also report used
ports in logfile.
Version 1.9.3
---------
* Move function call for backing up qemu disk information outside worker
threads: should fix occasional "Fatal Python error: _enter_buffered_busy"
error during backup.
Version 1.9.2
---------
* Return function if gathering qemu disk info fails for some reason.
* If remote backup is saved to local zip file, backup may fail because
absolute path to additional loader/nvram files is wrong.
* Fix naming if copy backup is saved to zip file output: dont append
checkpoint information to created files.
Version 1.9.1
---------
* Code cleanup: fix pylint warning, remove obsolete p.wait() calls with
hardcoded time limit, start adding type annotations, reworked imports.
* Fix disk detection with volume notation. (#81)
* Backup and restore qcow image related settings: during backup
qemu-img info is called on qcow based image devices and qcow specific options
are stored as json dump. If information is existent, on restore the
original settings of the qcow image (such as cluster size or other options)
are now applied during image creation. (#80)
* Fix some race conditions during restore of multiple disks and sequences: NBD
connection handle was not closed, following qemu-nbd calls would fail due
to locked files or already in use tcp ports.
Development:
* Change github workflows: now use ubuntu 22.04 and add test for remote
backup via localhost.
Version 1.9
---------
* Update README
* Make --compress option configurable, it is now possible to set
compression level (--compress=X) (#77)

Version 0.89
---------
* virtnbdrestore: check if additional boot files such as nvram/kernel images
exist and if not, restore them to the original path instead of just warning
the user about manual steps being required.
Version 0.88
---------
* virtnbdrestore: Allow restore into non-empty directories, so one can
restore the disk files into an existing libvirt managed volume directory.
If the restore target path is an libvirt managed pool, refresh the
pool contents. (#67)

instead of running into "Cannot acquire state change lock" timeout exception.
Version 0.76
---------
* virtnbdbackup:
+ Change some log messages: more detailed report on skipped devices during backup.
+ Add option --freeze-mountpoint: during backup, only filesystems of
specified mountpoints are freezed and thawed. (#60)

Version 0.69
---------
* Code cleanup
* virtnbdbackup: exit early if removing checkpoints fails during full
backup.
* virtnbdrestore: do not write zeroes during restore of image, as the
resulting zeroed regions are then reported as being "data": this would result
in further backups of the virtual machine to be thick provisioned, as even
zeroed regions are saved. (#56)
* virtnbdrestore: dont adjust vm config if option -c is missing.
* virtnbdrestore: now removes existent backing stores if adjust setting is
enabled: usually the case if virtual machine operated on snapshot during
backup.

backups on the same system concurrently.
* virtnbdmap: better error handling if nbdkit process fails to start.
* Update README
Version 0.62
---------
* Add script to create virtualenv with required dependencies.
* virtnbdmap now supports mounting of full->incremental (or differential)
chains: the current approach is to use the nbdkit COW (copy on write) filter
to replay the data blocks against the mapped nbd device.
Version 0.61
---------
* Add vagrant scripts
* Print libvirt library version.
* Disable xml based check if incremental backup capability is enabled for
libvirt versions > 8002000: feature is enabled by default. (#4)
Version 0.60
---------
* Add python3-dataclasses to RPM dependencies.
* Update README
Version 0.59
---------
* Add epilog to help output with some example commands
* Update README
Version 0.58

Version 0.56
---------
* Fix for Issue (#40): redefining checkpoints fails
Version 0.55
---------
* Correct some wrongly caught exceptions
* Update README
Version 0.54
---------
* (#38) Backup virtual machines loader bios and nvram if defined, provide
notice to user during restore that files must be copied manually.
* virtnbdrestore: Fixes for --until option:
+ would not stop processing further files since --sequence option was introduced
+ would stop before actually processing specified checkpoint, now function
stops after restoring data of checkpoint to be reached.
+ extend tests
* Update README
Version 0.53
---------
* Cleanup codebase
* Fix differential backup for offline domains: apply same logic as during
incremental backup.
Version 0.52
---------
* Update help regarding --qemu option: works with diff/inc now too
* Group possible options in help output
* Introduce more exceptions, cleanup codebase.
Version 0.51
---------
* Cleanup codebase, no functional changes.
Version 0.50
---------
* Fix sequence restore: function returned too early.
* Parameter for --sequence option does not require absolute path anymore.
Version 0.49
---------
* virtnbdrestore now support restoring a manual sequence of data files
passed by the --sequence option.
Version 0.48
---------
* Internal code changes: start using proper exceptions if stream format
is not parseable
* virtnbdbrestore: add --sequence option, allows to specify a comma separated
list of backup files whose information should be dumped. Next step is to
implement restore of a specified sequence.
Version 0.47
---------
* Fix issue #37: If an backup directory contains multiple differential
or incremental backups, its not possible to use the --until option for
point in time restore, because the differential backups defaulted to
the first checkpoint name in the metadata header. Recover would
stop too early in such cases..
Now the checkpoint name in the metadata header contains the same timestamp as
the target files, which make it possible to use the --until option too.
Version 0.46
---------
* Add changelog file
Version 0.45
---------
* Adds differential backup option: backup option -l diff now saves the
delta since the last incremental or full backup. Option -q now uses
nbdinfo instead of qemu-img map, which supports reading specific bitmap
information: now option -q can be used during incremental/differential backup
too,which might be good for debugging issues.
* If incremental backup for offline Domain is attempted, backup would save all
data, not just dirty extents: now saves only dirty extents.
* Extends the testsuite with tests for the implemented new features
* Fixes various pylint warnings, better error handling in some situations.
* Update documentation and executable dependencies for the debian package build.
**Full Changelog**: https://github.com/abbbi/virtnbdbackup/compare/v0.44...v0.45
Version 0.44
---------
Ensure checkpoint chain consistency:
As discussed during issue #33, the "parent" option to a checkpoint
created is readonly currently. Thus, virtnbdbackup can not force
an parent checkpoint during creation of the actual checkpoints.
This means we cannot ensure that the complete checkpoint chain
we are based on for the current incremental backup is entirely
created by us, like so:
> virsh checkpoint-list vm1 --tree
> virtnbdbackup.0 r
> |
> +- virtnbdbackup.1
> |
> +- virtnbdbackup.2
> |
> +- not-our-checkpoint
The delta for "not our checkpoint" would never be saved because
we dont know about this checkpoint.
Now virtnbdbackup checks for checkpoints which might have been
created by users or third party applications and exits with
error if incremental or full backup is attempted.
**Full Changelog**: https://github.com/abbbi/virtnbdbackup/compare/v0.43...v0.44
Version 0.43
---------
Remove --checkpoint option: has never behaved the way it should. The parent
option to a checkpoint XML definition is, according to the documentation read
only. So currently its not supported to force a specific checkpoint using this
option.
**Full Changelog**: https://github.com/abbbi/virtnbdbackup/compare/v0.42...v0.43
Version 0.42
---------
* Fixes some pylint/flake8 warnings.
**Full Changelog**: https://github.com/abbbi/virtnbdbackup/compare/v0.41...v0.42
Version 0.41
---------
Minor code changes regards checkpoint handling, fix some pylint warnings.
**Full Changelog**: https://github.com/abbbi/virtnbdbackup/compare/v0.40...v0.41
Version 0.40
---------
Introduce custom handler for logging facility to track number of warnings
during backup operation.
Recent changes introduce a new logging facility handler that counts the number
of warnings during backup (for example if qemu agent is not
reachable etc..)
If option "--strict" is set during backup, the exit code will now set to
2.
This allows calling applications or scripts to have a more detailed
error handling in regards to warnings and/or errors.
**Full Changelog**: https://github.com/abbbi/virtnbdbackup/compare/v0.39...v0.40
Version 0.39
---------
Adds full support for offline domains:
* Allows for incremental backup of offline domains: changed data for last
checkpoint will be saved until a new checkpoint is created. * Adds proper
error handling for cases where starting the NBD server for offline domains
causes error
**Full Changelog**: https://github.com/abbbi/virtnbdbackup/compare/v0.38...v0.39
Version 0.38
---------
Add support for backup of shutdown domains (#27)
Usually virtnbdbackup makes most sense while operating
on running domains. Only if a virtual domain is running,
checkpoints can be defined via libvirt API and the
required backup operations can be executed. The qemu
Process will then start the NBD backend in order to
receive the backup data.
With the recent changes, virtnbdbackup now detects
if the backup source is offline and then:
* Forces the backup mode to "copy": no full or
incremental backup supported because we can't create
an checkpoint via libvirt API. Copy type backup
is like a full backup just without checkpoint.
* Forces the amount of workers to 1
* Starts an NBD Process via qemu-nbd for each disk, operating
directly on the Virtual Disk files as detected from the VM
configuration.
* Queries required extents and data from the NBD
Service and saves it accordingly.
