Version 0.23.0
Read "doc/upgrade_to_v0.23.0.md" if updating from btrbk-v0.22.0.
Please read the updated description of the "run" command in btrbk(1),
as well as the "RETENTION POLICY" section in btrbk.conf(5) for a
detailed description of the new functionality.
man doc/btrbk.1
man doc/btrbk.conf.5
After updating your configuration, make sure no important backups get
deleted before doing the real run and run:
btrbk --print-schedule dryrun
ChangeLog:
* INCOMPATIBLE CONFIGURATION:
* Please read "doc/upgrade_to_v0.23.0.md" for details on updating
the configuration file (/etc/btrbk/btrbk.conf).
* Dropped "btrfs_progs_compat" option. Need btrfs-progs >= v3.18.
* Removed "resume_missing" configuration option.
* Create backups only if needed to satisfy retention policy.
* Preserve FIRST backup of hour/day/week/month instead of LAST.
* Replaced "{snapshot,target}_preserve_{daily,weekly,monthly}"
configuration options with "{snapshot,target}_preserve_min" and
"{snapshot,target}_preserve NNh NNd NNw NNm NNy" options.
* Added hourly/yearly retention policies (close: #36, #69).
* Allow regular directories for send-receive targets (close: #77).
* Allow wildcards in subvolume section (close: #71).
* Propagate targets defined in "volume" or "root" context to all
"subvolume" sections (close: #78).
* Added "archive" command (close: #79).
* Changed output format of "origin" command, add table formats.
* Added configuration option "rate_limit" (close: #72).
* Added new timestamp_format "long-iso", having a timezone postfix.
* Added "--print-schedule" command line option.
* Detect interrupted transfers of raw targets (close: #75).
* Always read "readonly" flag (additional call to btrfs-progs).
* Warn on receive targets at unexpected location (instead of abort).
* On incremental send/receive, use all snapshots sharing same
parent_uuid as candidates for "-p <parent>" instead of only older
snapshots. As last resort, use subvolumes in snapshot_dir matching
btrbk file name scheme as candidates (which allows incremental
backups after the parent vanished, e.g. after backup restore).
* Use perl built-in Time::Local instead of Date::Calc.
* Improvements of internal data structures.

btrbk does not detect interrupted transfers of raw targets (other than filesize==0).
While btrbk is not able to check the integrity of raw targets (as there is no tool that does only checks on a send-stream without writing it into a subvolume), btrbk should at least detect interrupted transfers.
A simple way to achieve this is to write to
xxx.btrfs.part, and only move it toxxx.btrfson success. This would also allowbtrfs cleanto identify and delete partial transfers, as well asbtrfs list backupsto mark them as "incomplete".The text was updated successfully, but these errors were encountered:
