Backup with two external drives

[SebGG]

I have a problem, but maybe its just an misunderstanding of how the backup process works...

i have two drives for backup
i want to use one for the main backup and the the other one for a backup lets say every month
i thought thats its possible two change in the backup configuration tab between the two drives
but when in change the configuration from the main to the second drive, then make a fresh backup to thie second drive and after that change the configuration back to the main drive, the main drive runs out of space.
is this not possible? Because i thought that the backup process recognize that there are old backups on the main drive and it starts from there and not from new?

Hi, has anyone a hint or solution for me? Thanks

Personally I would not change backup configs in this way.
I would leave the backup going to the the primary drive.
Then I would use something like rclone and a cron job to copy selected backups off the primary drive to the secondary drive.

I assume you are using rsync ? The "state" is stored on Cloudron server itself and not in the external disk. This is the reason you are seeing a fresh backup being made when you change the disk. As @timconsidine said, I would not change the backup configs this way. It's not really designed to be used the way you are expecting (but we have something like in our roadmap for 8.0).

What I would do is to leave one disk in place all the time. Then, have another script in place which copies over backups from this one disk to another disk in your own schedule. Maybe just set up some crob job on the server for this?
