Since 2016, I’ve had a fileserver mostly just for backups. System is on 1 drive, RAID6 for files, and semi-annual cold backup.
I was playing with Photoprism, and their docs say “we recommend placing the storage folder on a local SSD drive for best performance.” In this case, the storage folder holds basically everything but the pictures themselves such as the database files.
Up until now, if I lost any database files, it was just a matter of rebuilding them by re-indexing my photos or whatever, but I’m looking for something more robust since I’ll have some friends/family using Pixelfed, Matrix, etc.
So my question is: Is it a valid strategy to keep database files on the SSD with some kind of nightly backup to RAID, or should I just store the whole lot on the RAID from the get go? Or does it even matter if all of these databases can fit in RAM anyway?
edit: I’m just now learning of ZFS caching which might be my answer.
I’ve heard that too. Hmm.
Up until recently, the server mostly hosted a photo library and media library that didn’t tend to change very often. So a hdd in a fireproof save updated once a year was enough for me.
I guess I’ll have to come up with a better solution. What would you recommend for automatic backups? I’m trying to avoid 3rd party services.
I’ve switched to restic for my backups and have been very happy with it. Very fast, encrypted and snapshot history.
