check_borg

Check borg repository for date of latest archive.

Usable with nagios, icinga2 or any other nagios-fork.

Usage

./check_borg [ -C CONF ] [ -R <borg-repo-url> ] [ -P <borg-archivename-prefix> ] [ -c <date> ] [ -w <date> ]

<date> can be any valid format parsable by the date-command. So last day or 12 hours ago would be valid dates.

-R can be omitted, when BORG_REPO is set in the environment.

CONF is a file, which will get sourced. It can export variables like BORG_PASSPHRASE and BORG_REPO. You can separate with this file your borg specific secrets from the icinga2 configuration.

Non-standard executable paths

• If your borg executable is not installed in your $PATH or is not called borg, you can define the environment variable BORG to point to the correct command.
• If the GNU date executable is not installed as date, you can set the environment variable DATE to point to the correct date command.

Passwords

Export BORG_PASSPHRASE.

Requirements

• GNU's version of date.
• borgbackup

Warnings

• Be sure about the implications, when monitoring a repository secured with a passphrase.
• I don't know how to exclude checkpoints in borg list in combination with --format='{time}{NUL}'.
