Storage Settings
To specify storage settings for the Veeam Agent backup job managed by the backup server:
- Click Advanced at the Storage step of the wizard.
- Click the Storage tab.
- From the Compression level list, select a compression level for the backup: None, Dedupe-friendly, Optimal, High or Extreme. To learn more about the compression levels, see the Data Compression section in the Veeam Agent for Microsoft Windows User Guide.
- In the Storage optimization section, select what type of backup target you plan to use. Depending on the chosen storage type, Veeam Agent for Linux will use data blocks of different size to optimize the size of backup files and job performance: 4 MB, 1 MB, 512 KB or 256 KB.
|
If you change the storage optimization settings for the backup job, new settings will not have any effect on previously created files in the chain. They will be applied to new files created after the settings were changed. To apply new storage optimization settings in backup jobs, you must create an active full backup after you change storage optimization settings. Veeam Backup & Replication will use the new block size for the active full backup and subsequent backup files in the backup chain. To learn about the active full backup, see Performing Active Full Backup. |
- To encrypt the content of backup files, select the Enable backup file encryption check box. In the Password field, select a password that you want to use for encryption. If you have not created the password beforehand, click Add or use the Manage passwords link to specify a new password. For more information, see the Password Manager section in the Veeam Backup & Replication User Guide.
If the backup server is not connected to Veeam Backup Enterprise Manager, you will not be able to restore data from encrypted backups in case you lose the password. Veeam Backup & Replication will display a warning about it: Loss protection disabled. For more information, see the Decrypting Data Without Password section in the Veeam Backup & Replication User Guide.
You can select a Key Management System (KMS) server in the Password field. The KMS server must be added to Veeam Backup & Replication in advance. If you choose to use KMS keys for backup file encryption at this step of the wizard, Veeam Backup & Replication immediately starts communication with the KMS server to retrieve the encryption keys. To learn more, see the Key Management System Keys section in the Veeam Backup & Replication User Guide.

Consider the following:
|
If you plan to encrypt the content of backup files, consider the following limitations:
- If you enable encryption for an existing Veeam Agent backup, during the next job session Veeam Agent for Linux will create a full backup file. The created full backup file and subsequent incremental backup files in the backup chain will be encrypted with the specified password.
- Encryption is not retroactive. If you enable encryption for an existing backup job, Veeam Agent for Linux will encrypt the backup chain starting from the next restore point created with this job.
