Viewing space savings

You can monitor the space savings for each DSU using the snapvault status –b command.

Step

To see how much space is saved, enter the following command in the console of the secondary storage system: snapvault status -b

The amount of time it takes for the snapvault status -b operation to complete depends on how many backups were created on the volumes; therefore, the operation might take a long time to complete.

Examples

The following is a sample output of the snapvault status -b command:

filer1> snapvault status -b

Snapvault secondary is ON.
Volume       actual   used   saved   %saved  ratio
------       ------   ----   -----   ------  -----
subvol3_dst  50403MB  3525MB 46877MB  93%    14.29:1

To abort the snapvault status -b operation at any time, enter the following command:Cntl+C

The result of the snapvault status -b command is a list of volumes that contain NetBackup client data and information about space savings. The following list describes the information displayed by the snapvault status -b command:

actual—Total disk space used on the volume by all of the tar files sent from the NetBackup application. This value represents the tar image files only and does not include any of the internal metafiles that might be associated with the backups.
used—Total space used on the volume by the active file system and Snapshot copies. This value is equivalent to the sum of the values returned by the df command for space used by the active file system and the Snapshot copy.
saved—Total space saved on the volume. This is equivalent to the actual value minus the used value. In the case when the actual value is less than the used value, this field is 0.
%saved—Percentage of storage saved. In the case where there is no space savings, this field is 0.
ratio—Ratio of shared block data to unshared block data. When there are no space savings, this field is 1:1.
