Reference Guide

The type of disk group that the virtual
disk is on.
Backup Exec creates only physical disk
groups with a disk classification of Stripe
with parity (RAID 5). If another disk
classification appears, the disk group was
created with an application other than
the Storage Provisioning Option.
Disk classification
Type the maximum size for each file that
is contained on this virtual disk. Select
either MB or GB. The file size can be from
one MB to 4096 GB. The default is four
GB.
If you create small but numerous files,
performance may slow since the
computer must still process each file.
However, if you create large files, file
system limitations can cause memory
allocation problems or network issues.
These issues can be a problem if you store
files across a network.
Maximum file size
Type the maximum number of backup
sets to write to each virtual disk file. The
maximum number can range from one to
8192. The default number is 100.
If you specify fewer rather than more
backup sets in a file, Backup Exec may be
able to reclaim disk space faster. For
example, you specify 100 backup sets per
file. Backup Exec cannot reclaim any disk
space until the overwrite protection
period expires for all of the backup sets.
If you specify one backup set per file,
Backup Exec can reclaim disk space as
soon as the overwrite protection period
expires for that set.
Maximum number of backup sets per file
Type the number of concurrent
operations that you want to allow to this
virtual disk. This number can range from
one to 16. The default number is one.
