btrfs-sxbackup ************** Btrfs snapshot backup utility * Push/pull support via SSH * Retention * Email notifications * Compression of transferred data * Syslog logging System dependencies =================== Required -------- The following packages have to be available on both source and destination * bash * btrfs-progs The system executing btrfs-backup requires * python3 Optional -------- * ssh (for remote push/pull, not required for local operation) * bash has to be set as the default remote shell for the user running the backup * lzop (for compression support if desired) * pv (provides progress indication if installed) * sendmail (for email notifications if desired) Installation ============ .. code :: pip3 install btrfs-sxbackup Setup ===== * when using ssh, public/private key authentication should be set up Known limitations ================= * the destination filesystem has to be mounted without the subvol option, otherwise an error will occur on btrfs receive prompting you to remount with fs tree * some commands (like *update*) may not be available for backup jobs created with older versions of btrfs-sxbackup. in this case backup jobs can be recreated using *destroy* and *init*. existing snapshots will be kept as long as *destroy* is **not** invoked with *--purge*. Usage examples ============== Initialize ---------- Initialize a backup job pulling snapshots of subvolume **/** on remote host **myhost.org** to local subvolume **/backup/myhost** .. code :: btrfs-sxbackup init ssh://root@myhost.org:/ /backup/myhost Initialize a backup job pushing snapshots of local subvolume **/** to remote subvolume **/backup/myhost** on host **mybackupserver.org** .. code :: btrfs-sxbackup init / ssh://root@mybackupserver.org:/backup/myhost Run --- Run a backup job .. code :: btrfs-sxbackup run /backup/myhost Cron ---- Cronjob performing a pull backup job .. code :: # /etc/cron.d/btrfs-sxbackup PATH="/usr/sbin:/usr/bin:/sbin:/bin" 30 2 * * * root btrfs-sxbackup run /backup/myhost Synopsis and options ==================== .. code :: usage: btrfs-sxbackup [-h] [-q] [--version] [-v] {init,destroy,update,run,info,transfer} ... positional arguments: {init,destroy,update,run,info,transfer} init initialize backup job destroy destroy backup job update update backup job run run backup job info backup job info purge purge backups according to retention expressions transfer transfer snapshot optional arguments: -h, --help show this help message and exit -q, --quiet do not log to stdout --version show program's version number and exit -v can be specified multiple times to increase verbosity init ---- .. code :: usage: btrfs-sxbackup init [-h] [-sr SOURCE_RETENTION] [-dr DESTINATION_RETENTION] [-c] source-subvolume destination-subvolume positional arguments: source-subvolume source subvolume to backup. local path or ssh url destination-subvolume destination subvolume receiving backup snapshots. local path or ssh url optional arguments: -h, --help show this help message and exit -sr SOURCE_RETENTION, --source-retention SOURCE_RETENTION expression defining which source snapshots to retain/cleanup. can be a static number (of backups) or more complex expression like "1d:4/d, 1w:daily, 2m:none" literally translating to: "1 day from now keep 4 backups a day, 1 week from now keep daily backups, 2 months from now keep none" -dr DESTINATION_RETENTION, --destination-retention DESTINATION_RETENTION expression defining which destination snapshots to retain/cleanup. can be a static number (of backups) or more complex expression (see --source-retention argument) -c, --compress enables compression during transmission.

Requires lzop to be installed on both source and destination Changelog ========= 0.6.10 ------ * FIXED username should be checked for `None` when building ssh url 0.6.9 ----- * RESOLVED #32 regression, always transferring full snapshots 0.6.8 ----- * RESOLVED #31 Error when destination has no snapshots 0.6.7 ----- * FIXED #30: full snapshot warning breaks local jobs (having no destination) * RESOLVED #29: can't destroy when destination unavailable 0.6.6 ----- * ADDED support for retain timespan multiplier (eg. '1/4m' -> keep 1 in 4 months) and yearly timespan literal ('y'), resolving #28 0.6.5 ----- * RESOLVED #18, improved error output 0.6.4 ----- * ADDED support for falling back to transferring full snapshot if latest snapshot (timestamp) does not match on source/destination 0.6.3 ----- * FIXED exception during exception handling in main method 0.6.2 ----- * FIXED pip installation may fail with bdist/wheel 0.6.1 ----- * README update 0.6.0 ----- * ADDED support for purge command 0.5.9 ----- * ADDED license headers to all source files, no functional changes 0.5.8 ----- * FIXED job won't run due to inconsistent datetime comparison (offset-naive/aware) 0.5.7 ----- * ADDED local timestamps to info, resolving #14 0.5.6 ----- * Fixed #13 "update" command always activates compression, regardless of -c 0.5.5 ----- * Fixed retention breakage which could occur when first/earliest expression kept 1 backup per interval 0.5.4 ----- * Python 3.3 compatibility fixes * Added proper support for relative paths passed to init 0.5.0 ----- * New command line interface * Source container subvolume path is now **.sxbackup** relative to the source subvolume and cannot be customized anylonger * Backups created with older versions are still supported. If you customized the source container subvolume, this will still work, but it's recommended to rename it to the new default (**.sxbackup**) and update source and destination configuration files (.btrfs-sxbackup) accordingly
