Dell PowerVault DL2000 - Manual (Page 40)

3 Set the following defaults as appropriate:
Type the maximum number of backup sets
to write to a virtual disk. The maximum Maximum number of backup sets per file
number can be from one to 8192. The
default 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.
Type the maximum size for each file that
this virtual disk contains. Select either MB Maximum size for files
or GB as the unit of size. The file size can
be from one MB to 4096 GB. The default
size is four GB.
If you create small but numerous files,
performance may be slow since the
computer must still process each file.
However, if you create large files, file
system limitations can cause memory
allocation issues or network issues. These
issues can be a problem if you store files
across a network.
Type the number of concurrent operations
that you want to allow to this virtual disk.
This number can be from one to 16. Allow x concurrent jobs
Type the low disk space threshold at
which you want Backup Exec to send the Threshold 1
first of three alerts. The default is 75%,
which is a percentage of the total available
disk space on this virtual disk. You can
change the default, and you can change
the amount of space from a percentage to
megabytes or gigabytes.
