64-bit operating system
The storage node must be installed in a 64-bit operating system. The machine with the storage node
should not run applications that require much system resources; for example, Database
Management Systems (DBMS) or Enterprise Resource Planning (ERP) systems.
Multi-core processor with at least 2.5 GHz clock rate
We recommend that you use a processor with the number of cores not less than 4 and the clock rate
not less than 2.5 GHz.
Sufficient free space in the vault
Indexing of a backup requires as much free space as the backed-up data occupies immediately after
saving it to the vault. Without a compression or deduplication at source, this value is equal to the size
of the original data backed up during the given backup operation.
High-speed LAN
1-Gbit LAN is recommended. It will allow the software to perform 5-6 backups with deduplication in
parallel, and the speed will not reduce considerably.
Back up a typical machine before backing up several machines with similar contents
When backing up several machines with similar contents, it is recommended that you back up one
machine first and wait until the end of the backed-up data indexing. After that, the other machines
will be backed up faster owing to the efficient deduplication. Because the first machine's backup has
been indexed, most of the data is already in the deduplication data store.
Back up different machines at different times
If you back up a large number of machines, spread out the backup operations over time. To do this,
create several backup plans with various schedules.
Use fast cataloging
Indexing of a backup starts after its cataloging has been completed. To reduce the overall time
required for backup processing, switch automatic cataloging (p. 109) to the fast mode. You can start
full cataloging manually outside of the backup window.
Configure alert notifications
It is recommended that you configure the "Vaults" alert notification (p. 397) in the management
server options. This can help you to promptly react in out-of-order situations. For example, a timely
reaction to a "There is a vault with low free space" alert can prevent an error when next backing up
to the vault.
7.5.7.5 Deduplication restrictions
Common restrictions
Deduplication cannot be performed if you protected the archive with a password. Data blocks of
password-protected archives are stored in the backups as they would be in a non-deduplicating
vault.
If you want to protect an archive while still allowing it to be deduplicated, leave the archive
non-password-protected and encrypt the deduplicating vault itself with a password. You can do this
when creating the vault.
