ACRONIS Backup & Recovery 10 Advanced Server Virtual Edition User Manual page 134

Specify a local folder on the storage server to create a vault-specific database. This database
will store the metadata required for cataloguing the archives and performing deduplication.
Deduplication
[Optional] Select whether to enable archive deduplication in the vault. Deduplication
minimizes storage space taken by the archives and backup traffic. It reduces the size of
archives in the vault by eliminating redundant data such as duplicate files or disk blocks.
Deduplication is not possible on tape devices.
To learn more about how deduplication works, see the Deduplication (p. 72) section.
Compression
[Optional] Select whether to compress the deduplication data store. This setting is available
only if deduplication is enabled.
Encryption (p. 135)
[Optional] Select whether to protect the vault with encryption. Anything written to the vault
will be encrypted and anything read from it will be decrypted transparently by the storage
node, using a vault-specific encryption key stored on the storage node.
After you have performed all the required steps, click OK to commit creating the managed vault.
Vault path
To specify the path where the managed vault will be created
1. Enter the full path to the folder in the Path field or select the desired folder in the folders tree.
Managed vaults can be organized:

on the hard drives local to the storage node

on a network share

on a Storage Area Network (SAN)
 on a Network Attached Storage (NAS)
 on a tape library locally attached to the storage node.
To create a new folder for the vault in the selected location, click
2. Click OK.
A vault can be created in an empty folder only.
We do not recommend creating a deduplicating managed vault on a FAT32 volume. The reason is that such
vault stores all deduplicated items in two potentially large files. Because the maximum file size in the FAT file
systems is limited to 4 GB, the storage node may stop working when this limit is reached.
The folder permissions must allow the user account under which the storage node's service is running (by
default, ASN User) to write to the folder. When assigning permissions, specify the user account explicitly (not
just Everyone).
Vault database path
To specify the path where the vault's database will be created
1. In the Local folders of the storage node, select the desired folder or enter the full path to the
folder in the Path field.
To create a new folder for the database, click
2. Click OK.
When choosing a folder for the vault's database, follow these considerations:
