6.1.3 Column values
The GetVaultsStatistics function returns a table that contains the following columns:
 Date – The point in time for which the statistics are presented
 FreeSpace – The amount of free space in the managed vault—normally, the amount of free space
on the device that stores the managed vault
 OccupiedSpace – The space occupied by all archives that are stored in the managed vault, plus
the size of the vault database and—for deduplicated vaults—the size of the deduplication data
store
 NumberOfArchives – The number of archives that are stored in the managed vault
 NumberOfBackups – The total number of backups that are contained within the archives in the
managed vault
The following four columns contain information about the size of the data in the archives, in
bytes. It is calculated based on the archive sizes shown in the ArchivesAndBackups view (p. 15).
 OriginalDataSize – The sum of the values in the ArchiveOriginalDataSize column for all archives
that are stored in the managed vault
 ArchiveDataSize – The sum of the values in the ArchiveBackedUpDataSize column for all archives
that are stored in the managed vault
 UniqueDataSize – The sum of the values in the ArchiveUniqueDataSize column for all archives
that are stored in the managed vault. For a non-deduplicated vault, the value in this column is
NULL.
 DeduplicatedArchiveSize – The amount of data in the archives that was removed as a result of
deduplication. For a non-deduplicated vault, the value in this column is 0. For a deduplicated
vault, the value in this column is the value in ArchiveDataSize minus the value in UniqueDataSize.
The following four columns contain information about data ratios for the contents of the
managed vault. Smaller ratios mean higher storage efficiency.
These ratios are calculated based on the sizes shown in the previous four columns.
 TotalRatio – The value in OccupiedSpace divided by the value in OriginalDataSize. This ratio
shows the space actually occupied by the archives as compared with the overall size of the sets of
data that can be recovered from these archives. For an example on original data size, see Original
data size (p. 17).
 BackedUpDataRatio – The value in ArchiveDataSize divided by the value in OriginalDataSize. This
ratio shows how the use of incremental and differential backups has reduced the space needed
to store the sets of data in the archives.
 DeduplicationRatio – The value in UniqueDataSize divided by the value in ArchiveDataSize. This
ratio shows how deduplication alone has reduced the space needed for the archives. For a non-
deduplicated vault, the value in this column is NULL.
 CompressionRatio – The value in OccupiedSpace divided by the value in ArchiveDataSize. This
ratio shows how deduplication (for deduplicated vaults) and archive compression have reduced
the space needed for the archives.
 VaultName – The name of the managed vault
 VaultID – The unique identifier of the managed vault
 StorageNodeName – The name of the computer on which the storage node that manages the
vault is installed
 StorageURI – The same as the StoragePath column of the Vaults view
 IsEncrypted – Equals 1 if the managed vault is encrypted; otherwise, equals 0
