Storage Settings

To specify storage settings for the backup policy:

  1. Click Advanced at one of the following steps of the wizard:
  • Storage — if you have selected to save backup files in a Veeam backup repository or cloud repository.
  • Local Storage — if you have selected to save backup files in a local storage of a Veeam Agent computer.
  • Shared Folder — if you have selected to save backup files in a network shared folder.
  1. Click the Storage tab.
  2. 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 Linux User Guide.
  3. In the Storage optimization section, select what size of data blocks you plan to use: 4 MB, 1 MB, 512 KB, 256 KB. Veeam Agent for Microsoft Windows will use data blocks of the chosen size to optimize the size of backup files and job performance.

Storage SettingsNOTE

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.

  1. 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. For more information, see the Decrypting Data Without Password section in the Veeam Backup & Replication User Guide.

Storage SettingsNOTE

Consider the following:

  • You must encrypt the backup job if you want to back up data to the Veeam Data Vault storage.
  • You cannot use Key Management System (KMS) keys for data encryption with a Veeam Agent backup policy. To be able to use KMS keys, create a backup job managed by the backup server.

To learn more about KMS keys, see the Key Management System Keys section in the Veeam Backup & Replication User Guide.

Data Encryption Limitations

If you plan to encrypt the content of backup files, consider the following limitations:

For backup policies targeted at a Veeam backup repository, all data encryption operations are performed in Veeam Backup & Replication. Encryption settings are passed to a Veeam Agent computer only in case this computer is added to a backup policy targeted at a local drive of a protected computer, at an SMB network shared folder, or at a cloud repository. Veeam Backup & Replication passes encryption settings when applying the backup policy to a protected computer.

This scenario differs from the same scenario in earlier versions of Veeam Backup & Replication where all backups created for Veeam Agent computers in the backup policy could be accessed from any computer in the backup policy without providing a password.
