Can the backup folder be split at some level and the files still be useful?
-
I installed UNRAID on an older server and I'm using it as an NFS remote. I'm new to UNRAID and XCP. I noticed that when configuring the backup share I can tell it to keep whole folders together or allow them to be divided across drives based on the second, third, etc. folder depth.
I'm wondering at what level I can divide it and have the backups still be useful if drive failures caused me to lose drives. Not that I plan to lose drives but one thing I think is cool about UNRAID is that you can lose the array but still retain data on the drives that didn't fail. I just don't want to be left with files that aren't useful anyway.
Individual drives in the array aren't likely to work very long for retaining backup history because this server is limited to 2TB physical drives. I was thinking if the backup could be divided up so individual VM backup files are kept together but different VM backups might be on different drives in the array, then that would help spread the load. I worry that just having those files without the metadata in the parent folders might not be enough to actually perform a restore.

Under the xo-vm-backups directory is a series of directories named with UUID's that contain everything that belongs to a particular VM's backup. As long as you keep each directory and all the contents nested within it you will be able to restore that VM.

@lawrencesystems Excellent, that's what I was hoping to confirm.
