Is there any way to set up a share which will duplicate anything copied to it across multiple disks?

 

eg my photo collection is relatively small but very valuable to my family. I'd like to have the entire library on more than one disk, just in case of drive failure.

 

I don't mind doing it manually if necessary, but I don't want multiple top level shares called 'photos' for instance. Don't mind copying via disk shares directly

To my knowledge. No.

By default the server keeps parity to rebuild the lost disk.

 

If you wanted to manually copy your photos to two drives, it should be easy.

You can create a share called "photos" for example. You then assign "photos" to use disk1 (or more drives).

 

You could then create a second share called "photo backups". You would then assign "photo backups" to use a different drive(s),  say disk3 for example.

 

At this point you either can manually copy files to each share or automate it someway.

Ill guess the unraid expertets will to schedule an rsync from "photos" to "photos backup" to run every night or every few hours if it puts you at ease.

ok, thanks.

 

I have my backup drive set up to be disk 3 only, and my 'mixed media' (photos/music/home movies) to be disk 4, so that gives me effectively an extra level of failure survival. some of those are top level shares, some are just within a folder.

 

it would be good to have an unraid internal process that could sync those folders to my backup drive.

 

I'll have to look into rsync or similar. Or I can just interweave my chronosync backups to backup to 'photos' share on mon/wed/fri, and then backup the same job to 'backups/photos' on tues/thur. It'll be incremental so not too much overhead.

As I said. I'm not 100% sure how to do it. But it should work.

Create crontab to do an rsync on a schedule. Have it rsync  /mnt/user/photos with /mnt/user/photoBackup

 

The space might create an issue. I belive You will have to create the line in the go script to recreate the crontab.

 

I'd love to find this out myself. I'll be doing something similar with 2 unraid servers.
