I want to be able to back up the contents of my Big Array, to as many removable smaller hard disks as necessary, and only backup the changes each time.  I know I can do this in windows very easily, but was hoping there was a local or plugin solution already available, before I go down the WinVM or networking route.

 

Anyone have any thoughts and/or experience doing this?

I group four 6TB disks ( 24TB RAID0 ) to backup three of 8TB array disks, in same way, two 3TB disks to backup a 6TB disk.

 

I name those pools in 145 678 which corresponding to the 8TB disks no. All disks manage under Unraid and sync in local. That means spare minimum 4 bays for backup purpose, then swap in out different disk set(s).

What are you doing in terms of removing them after you make your backup?

Those slot were spare for array disk expansion.

So here's what I'm doing for the bulk storage backup:

• Bought a 20 pack of 4TB SAS disks (2 died in testing, but that's not really important. )
• Built a VM to run Windows 7 Embedded (because 8GB vDisk only has 3.5GB used) to run RoboCopy.
• Hot swap the disk into the machine, passthrough mount the disk to the VM, format as GBT NTFS.
• Run the RoboCopy script(s) against Cube's network share(s), predominantly clearing the Archive flag as it goes along.
• So far it appears to be doing what I want. It's a little "messy" in that it'll keep searching the entire share for files until it fills every bit of space on the disk, so near the end of the run it'll pick up a bunch of tiny files all over the place, but It's getting everything.
• Recovery would be a simple mount and copy back to the appropriate share(s).
