备份复制窗口
A backup copy window is a period of time when a backup copy job is allowed to transport data between source and target repositories.
By default, the backup copy window is configured to allow data transfer at any time. If you do not want the backup copy job to overlap the production hours, you can reduce the backup copy window and specify "prohibited" hours.
During the prohibited hours Veeam Backup & Replication cannot transfer data between source and target repositories. Other aspects of how Veeam Backup & Replication behaves during the prohibited hours and backup copy window depend on the selected backup copy mode. For more information, see Backup Copy Window and Prohibited Hours in Immediate Copy Mode and Backup Copy Window and Prohibited Hours in Periodic Copy Mode.
Note |
During the prohibited hours, Veeam Backup & Replication stops only data transferring operations. Transformation processes in the target repository are still performed. For more information, see Transformation Processes. |
Backup Copy Window and Prohibited Hours in Immediate Copy Mode
When the prohibited hours start, Veeam Backup & Replication stops backup copy job sessions during which data transfer was not finished and assigns Failed to the session statuses. During the prohibited hours, Veeam Backup & Replication does not start new backup copy job sessions.
When the backup copy window starts, Veeam Backup & Replication transfers all restore points that were not transferred and creates as many incremental backup files as were omitted.
Backup Copy Window and Prohibited Hours in Periodic Copy Mode
How Veeam Backup & Replication behaves during the prohibited hours and backup copy window depend on the length of the backup copy interval:
- If the backup copy interval is longer than the duration of the prohibited hours, Veeam Backup & Replication puts backup copy job sessions to the Idle state and postpones data transfer operations. When the backup copy window starts, Veeam Backup & Replication renews data transfer.
- If the backup copy interval is shorter than the duration of the prohibited hours, Veeam Backup & Replication finishes all backup copy job sessions and assigns Failed to the session statuses. During the first backup copy interval on the backup copy window, Veeam Backup & Replication aggregates all data changes between the latest restore point on the target backup repository and latest restore point in the source backup repository. Then, Veeam Backup & Replication transfers these changes to the target repository and writes them into one restore point.
