Title:  How You Can Manage Data which is staged When the Database Fails?

Description:

When you use the Disk to Disk to TapeOption to back up data, the information about the backup jobs, sessions, staging policies, and so on is stored in the CA ARCserve Backup database. If the database fails, and you need to recover the CA ARCserve Backup database which holds the staging policies for the data residing on the staging device (for example, a file system device or a library). The staging policy specifies the time limit to copy the data to the final destination media and when to purge the data from the staging device.
If the database fails:

  • CA ARCserve Backup cannot copy (migrate) the data on staging device to its final destination media.
  • CA ARCserve Backup cannot purge data from a file system device (FSD) to reclaim disk space. As a result, future backup jobs will probably fail due to an insufficient amount free disk space on the staging device.

Solution:

If the database fails and if you do not have a copy of the database for database recovery, you can use the tapecopy command line utility to copy all the backup data from the staging device to final destination media. (When you use this approach, media rotation rules, such as Friday tape or Monday tape may not be adhered to.) Then, you can use the -purge option from the Device Manager command line utility (ca_devmgr) to delete the data from the FSD and reclaim disk space.
