Thanks for the suggestion. As zstd is not standard on all operating systems, this is not operating system-independent. So a restore is possible as we use our docker but the backup file itself is not open-able on every system.

I strongly vote against any compression in backup creation. The user can compress backups afterward and store them compressed. I do a compressed upload every night for example. But this is total in user hand.

This also makes the command more error-prone, especially because of the spaces. An old backup cannot be restored with the command, etc.

ok, fine - would you consider a new page in "Guides" on how to backup (eg. daily) with a small backup script, compression options and crontab or is what we have enough?
