Central catalog and backup spanning multiple disks

Hi,

I am a happy user of restic for a couple of years now, thanks for the great tool. Recently, I thought about the problem that my NAS data will soon not fit onto a single 16TB USB HDD any more. Considering the current storage prices and the fact that I have a couple of 4TB and 1 TB drives from past times, I thought about splitting backups.

Is there an existing solution like a central catalog tool which allows to search for files and than points me to a drive I need to mount? Basically, splitting the catalog from the actual backup.

For the backup process, ideally I would just mount a disk with some remaining space and the new files would go there.

I think I could build something with rclone and union mounts, but that would require to mount all disks concurrently, which I don’t really want. Also, I don’t want to loose all data if a single drive fails.

Last but not least, I need to integrity check repos from time to time, but if it would be just a restic repo, that might be the easiest task.

I appreciate all ideas :slight_smile:
