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
