Description
This quota is for the amount of data a client sends to the device before
deduplication. If the quota is enabled and the quota limit is reached, backups will
fail to prevent the quota from being exceeded. The quota allows you to provide a
service to back up a particular amount of client data. For example, set this quota
when you charge clients per TB of user data protected.
NOTE: If you require capacity management, HPE recommends configuring
backup applications with quotas to reroute to another device or to postpone
backups to prevent backups from failing unexpectedly.
When a StoreOnce Catalyst store reaches its quota, the status of the StoreOnce
Catalyst store changes to "Online - Critical." The StoreOnce Catalyst Status
changes to "Fault." You can restore from that store but new backups will fail.
When the quota is no longer met, either by increasing the quota or by expiring
backups, the StoreOnce Catalyst store status and the overall StoreOnce Catalyst
status return to the "Running" state.
The logical data size of a StoreOnce Catalyst item is updated at every 1 GB of
physical data stored or when a StoreOnce Catalyst item is closed. In backups with
high deduplication ratios, it is possible for a logical data size quota to be exceeded
before the store prevents further backups. The physical data size quota, which
updates more frequently, is not affected. For example, if a logical data quota size
is set to 1 TB and the backup being performed has a deduplication ratio of 10:1, it
is possible that the logical data size quota will be exceeded by 10 GB.
Using this feature in conjunction with Client-Permissions to control client access to
the StoreOnce Catalyst store allows you to effectively define how much space a
particular client is allowed to use on the StoreOnce System. With many clients
using the same system, you can control how much disk space is available to
individual clients.
Check this box to enable data encryption. Encryption cannot be enabled after a
store is created; it must be enabled at store creation. Also, encryption cannot be
disabled once it has been set for a store. If enabled, encryption will be performed
prior to writing data to disk for this store.
For a Federated store: Store Encryption must be enabled (if licensed) or disabled
on all service sets in the team.
Once the library is created and the correct license is applied, the Secure Erase
Mode box appears on the Catalyst Store Details tab. The selection box defaults
to None, meaning Secure Erase is disabled. To enable Secure Erase, select the
preferred number of Overwrite Passes (1, 3, 5, or 7). If enabled, this feature allows
you to securely erase confidential data that may have unintentionally been backed
up as part of a regular backup job. See Security features on page 199 and
License management on page 188 for more information. On Cloud Bank stores,
Secure Erase Mode is disabled and not supported.
Checked if the store is Federated (configured at the time of store creation).
The number of members (service sets) in the Federation. This only displays if a
Federated store is selected.
