WSE 2016 - Server Backup - Volume Size Restrictions

B

Bunzena

Hi. Looking for some advice on what to do.

Have just migrated from WHS 2011 to WSE 2016 on an HPE GEN10 Microserver. We've installed a RAID controller with 4 x 8TB WD Reds in RAID 5 format.

So have a single drive pool of 21.8TB divided into two volumes [C: and D:]. The C drive has the OS - the D drive has the server folders and and shares. The C drive is 56 GB - the D drive 21.7 TB.

We've just set-up a back-up to an external RAID drive [RAID 1] to backup the entire server.

We're getting an error message for that backup - telling us that it only partially completes. The C drive backs up okay - but not the D drive. The message is that it cannot backup "volumes of more than 16TB".

[Actual message is "Volumes larger than 1677216 megabytes cannot be protected"]

There's not a lot online that we can find covering this. One solution would be to partition the D drive into two smaller volumes [perhaps one of 15 TB and one of c.6.8 TB]. But we're backing up a lot of data - so really would like to keep that single large volume - as we'll probably need it within the next 12 months.

Any thoughts on what we could do?
