为备份复制作业创建种子

Backup copy jobs have limitations for backups that can be used as seeds. The limitations are listed in the Map Backup File section.

To overcome these limitations, you can create a seed using a secondary backup copy job. To create a seed for the primary backup copy job, do the following:

1. Create a backup copy job. Add machines or backups whose restore points you want to copy to this backup copy job. Target the backup copy job to some backup repository on the source side. This backup repository will be used as an intermediate one.
2. Run the backup copy job to create a full backup file (VBK) in the intermediate backup repository.
3. Transfer the created VBK file and VBM file from the intermediate backup repository to the target backup repository.
4. Perform repository rescan to populate the target backup repository.

If the initial backup file was encrypted, you must enter a password to unlock the full backup file. Otherwise, Veeam Backup & Replication will not display the full backup file in the list of backups in the backup repository. For more information, see Importing Encrypted Backups.

5. Remap the backup copy job to the full backup file that you have created and transferred to the target backup repository.
6. Click Sync Now to start the backup copy.

As a result, Veeam Backup & Replication will use the full backup file as a seed. When a new restore point for the machine is available in the source backup repository, Veeam Backup & Replication will copy the restore point to the target backup repository and store it next to the full backup seed.

Specifying Backup Copy Interval for Periodic Copy Mode

When you configure a backup copy job, make sure that its backup copy interval covers the whole chain of restore points in the backup repository from which you plan to copy backups. The length of the backup copy interval has an impact on the algorithm of restore point selection. Veeam Backup & Replication copies only restore points that match the following criterion:

That is, if you have a backup chain whose earliest restore point is 1 week old, you need to set the backup copy interval to 1 week. If you set the backup copy interval to a smaller time interval, for example, 1 day, all restore points that are older than 1 day will fall out of the search scope, and Veeam Backup & Replication will not transfer such restore points.
