备份作业加密

Encryption for a backup job is configured in the advanced job settings. You should enable the encryption option and specify a password to protect data in backup files produced by the backup job.

The backup job processing with encryption enabled includes the following steps:

1. You enable encryption for a backup job and specify a password.
2. Veeam Backup & Replication generates the necessary keys to protect backup data.
3. Veeam Backup & Replication encrypts data blocks in the backup proxy, either the dedicated or default one, and transfers them to the backup repository already encrypted.
4. On the backup repository, encrypted data blocks are stored to a resulting backup file.

Restore of an encrypted backup file includes the following steps:

1. You import a backup file and define a password to decrypt the backup file. If the password has changed once or several times, you need to specify the password in the following manner:

• If you select a metadata file (VBM) for import, you must specify the latest password that was used to encrypt files in the backup chain.
• If you select a full backup file (VBK) for import, you must specify the whole set of passwords that were used to encrypt files in the backup chain.

2. Veeam Backup & Replication uses the provided passwords to generate user keys and unlock the subsequent keys for backup file decryption.
3. Veeam Backup & Replication retrieves data blocks from the backup file, sends them to the source side and decrypts them on the backup proxy, either the dedicated or default one.
