Currently, option arguments are only completed after =. For example:
$ btrbk --loglevel=<TAB>
debug error info trace warn
$ btrbk --loglevel <TAB>
archive diff extents ls prune run
stats clean dryrun list origin resume
snapshot usage
This commit makes it so that both option styles are recognized:
$ btrbk --loglevel=<TAB>
debug error info trace warn
$ btrbk --loglevel <TAB>
debug error info trace warn
This was the intention all along, but it was implemented incorrectly.
Add configurable prefix for each line of command output. Seems wrong,
but outsmarts the mail clients.
The problem is that some (most?) mail clients outsmart the specs and
replace text/plain mails by quotations, emoticons, emphasis, ...
The only "correct" solution is to disable these features in the mail
client.
Acceptable workaround for #376.
- If rsync is enabled, show number of created/deleted/transferred
files in mail subject.
- Add options to show summary and/or detail message in mail body.
- Add option to skip btrbk if no files were transferred via rsync.
- Add option to call sync(1) prior to running btrbk.
- Add option to skip btrbk execution if no files were transferred.
Using `WantedBy=multi-user.target` makes boot wait for btrbk.service
before it's considered "finished". This can be checked by running
`systemd-analyze` or checking the system log using `journalctl`.
Timers should use the "timers.target" target, see systemd.special(7).
btrbk <= 0.27.2 does not print "target_rsh" and "target_type" when
called with --format=raw, see $table_formats{resolved}. This is fixed
in 0.28.0.
Hardcoding target_type=send-receive is not so bad, as for raw targets
btrbk-verify complains first with:
btrbk-verify: missing required variable "target_rsh" in btrbk --format=raw line
So we should not run rsync (which is not really a problem, rsync just
fails with "not a directory").
Compare files and attributes by checksum, using rsync(1) in dry-run
mode with all preserve options enabled.
Resolves snapshot/backup pairs by evaluating the output of
"btrbk list latest [filter...]".
Restrictions:
- ".d..t...... ./" lines are ignored by default:
Root folder timestamp always differ.
- "cd+++++++++ .*" lines are ignored by default:
Nested subvolumes appear as new empty directories.
- btrbk raw targets are skipped
- rsync needs root in most cases (see --ssh-* options)
When used without --inplace, rsync creates a new copy of the file and
moves it into place when it is complete, having the effect that btrfs
creates a new extent for the WHOLE file. With --inplace however, rsync
writes the updated data directly to the destination file, having the
effect that btrfs creates a new extent only for the differing part of
the file.
