Configuring backup storage options
You can configure additional storage-related options for your primary and secondary backup storage hosts.
Procedure
To configure backup storage options for your registered disks, complete the following steps:
-
In the navigation pane, click System Configuration
,
.
The Disk Storage table lists the hostname of primary and secondary sites with the version and the capacity usage.
-
In the Disk Storage pane, click the settings icon
that is associated with the disk that
you want to update.
-
Select from the storage options as shown.
Enable Compression: Select this option to compress each incoming block of data by using a compression algorithm before the data is written to the storage pool. Compression consumes a moderate amount of additional CPU resources.
Enable Deduplication: Select this option so that each incoming block of data is hashed and compared against existing blocks in the storage pool. If compression is enabled, the data is compared after it is compressed. Duplicate blocks are skipped instead of being written to the pool. Deduplication is deselected by default because it consumes a large amount of memory resources (proportional to the amount of data in the pool) to maintain the deduplication table of block hashes.
Encryption Enabled: This option displays the encryption status of the primary or secondary backup storage host. Encryption can be enabled only during vSnap initialization. This option cannot be changed in this pane.
