How do you back up Nextcloud, installed as a snap, using the Backup app?

Selfhosted@lemmy.world – 20 points – 1 years ago

I have Nextcloud installed as a snap. I would like to back it up to a folder on a separate drive within the server. Nextcloud appears to have an official backup app, which I have installed on the Nextcloud instance.

Is it possible to connect a folder on a separate drive to Nextcloud running as a snap? What permissions should such a folder have?

I use nextcloud.export which comes with the snap (https://github.com/nextcloud-snap/nextcloud-snap/wiki/How-to-backup-your-instance), but the backup app looks nicer.

I have a weekly crontab that does...

...nextcloud.export -abc (everything except the data)
...a backintime snapshot of the raw data folder.

I'm not fully happy with this yet though.

The nextcloud.export -abc command makes a full export of the config, database and apps. So in contrast to backintime, which rebuilds each snapshot only in terms of the files that changed since the previous snapshot, I have a full-blown new backup of config, database and apps every week.
I put the nextcloud instance in maintenance mode while running both commands, so the config, database and apps should fit the snapshot of the raw data. But it still feels tricky. I would prefer to have just have one full "file-change-based" weekly (or daily?) snapshot of e.g. a VM. That's why I'm looking at this: https://docs.hanssonit.se/s/W6fMouPiqQz3_Mog/virtual-machines-vm/d/W6fMquPiqQz3_Moi/nextcloud-vm
