Backup too slow #1786

Open bassman56 opened 1 year ago

bassman56 commented 1 year ago

Description

The current daily backup now takes several hours to complete. The nextcloud is in maintenance mode all the time and not accessible. Why not create a snapshot (I use btrfs) and backup the snapshot instead? then we can go out of maintenance mode within a few seconds?

Example

# no change in interface. maybe an additional indicator whether backup is running in the background or not.

Backup seems to work normally for me, do you have data included in your backup and where do you store your backups (backup location)?

Hi,

I put all data into the backup, so the backup has about 350GB. The backup goes to a locally connected USB drive, capable of 50..100Mb/s So the whole backup blocks the nextcloud for about 2 hours in maintenance mode, with tendency to increase with more data on the nextcloud in the future.

My question: can you change the backup procedure to first make a snapshot (my data is on btrfs), then go out of maintenance and do the backup of the snapshot in the background?

Best Regards Christian

You can nc-snapshot-sync to the other HDD and do the backup to that path and exclude data. I think nc-snapshot-sync does not use maintainance mode, should not make sense anyway...
