Virtual tape drive compression
VTL’s compression saves disk space by compressing files so that more data can be
stored by a virtual tape drive. The increase in capacity is directly related to the
compressibility of the data being backed up. If you can compress the data being
backed up by a factor of up to 2:1, you can store up to twice as much information on
the virtual tape. Disk compression can vary depending upon the dataset; certain file
types (ZIP, PDF, GIF, RAR, etc.) are already compressed and cannot be compressed
further.
