Is there a drive size limitation with Backup Exec System Recovery (BESR) or Symantec System Recovery (SSR)?


Attempting to create a backup through an installed instance of Backup Exec System Recovery (BESR) / Symantec System Recovery (SSR) or, depending upon the product version, through the System Recovery Disk (SRD) will fail on either enumerating the client's drives or at 1% during a backup attempt by hanging if one or more of the drives are greater than sixteen terabytes (i.e. 16TB) in capacity.

Removing any drive(s) greater than 16 TB allows any remaining drives less than 16 TB to enumerate and backup successfully. Partitioning the > 16TB drive into partitions less than 16TB prior does not resolve this issue.


Currently BESR 8.0x through SSR 2013 does not support drives larger than 16 TB in size. 


Removing any drive(s) greater than 16 TB will resolve this issue.
