When using a deduplicating backup program (Borg, Restic, etc), using gzip is counter-productive because small changes in the input data stream can lead to much larger changes in the compressed data to backup.
As an alternative, some programs advise that you can use
gzip --rsyncable
, but uncompressed data is typically still preferred as it has a better chance of matching up with the existing chunks from prior backups.I propose that we update the docs to make Borg more space efficient as Immich will often have small daily changes to the database.
Also fixed some unquoted vars
