| How to inspect your backups |
Backup progress
By default, borgmatic runs proceed silently except in the case of errors. But if you'd like to to get additional information about the progress of the backup as it proceeds, use the verbosity option:
borgmatic --verbosity 1
This lists the files that borgmatic is archiving, which are those that are new or changed since the last backup.
Or, for even more progress and debug spew:
borgmatic --verbosity 2
Existing backups
Borgmatic provides convenient flags for Borg's list and info functionality:
borgmatic --list
borgmatic --info
Logging
By default, borgmatic logs to a local syslog-compatible daemon if one is
present. You can customize the log level used for syslog logging with the
--syslog-verbosity flag, and this is independent from the console logging
--verbosity flag described above. For instance, to disable syslog logging
except for errors:
borgmatic --syslog-verbosity 0
Or to increase syslog logging to include debug spew:
borgmatic --syslog-verbosity 2
systemd journal
If your local syslog daemon is systemd's journal, be aware that journald by
default throttles the rate at which a particular program can log. So you may
need to change the journald rate
limit
in /etc/systemd/journald.conf if you're finding that borgmatic journald logs
are missing.
Note that the sample borgmatic systemd service file already has this rate limit disabled.
Scripting borgmatic
To consume the output of borgmatic in other software, you can include an
optional --json flag with --create, --list, or --info to get the
output formatted as JSON.
Note that when you specify the --json flag, Borg's other non-JSON output is
suppressed so as not to interfere with the captured JSON. Also note that JSON
output only shows up at the console, and not in syslog.
