Backup Job Schedules and Rotations

You can configure your backup job to use a custom schedule, synthetic schedule, or a rotation scheme by using the Arcserve Backup template schemes or by specifying your own rotation parameters. You can also specify a repeat method and the following backup methods for each backup:

• Full (Keep Archive Bit)--Performed each time the job is repeated and keeps the archive bit.
• Full (Clear Archive Bit)--Performed each time the job is repeated and clears the archive bit.
• Incremental backup--Backs up only those files whose archive bits have been set since the last full or incremental backup was performed. After each backup, archive bits are reset so that they are not backed up during the next incremental backup job.
• Differential backup--Backs up only those files whose archive bits have been set since the last full backup was performed. Because differential backup jobs do not clear a file’s archive bit, the files that were backed up in the last differential job are backed up again. It takes longer to process backup jobs using this method. However, this strategy requires only two sets of media to restore a differential backup; the full media set, and the differential media set. In the case of an incremental backup, you require the full media set and every incremental set until the latest set. For a synthetic full backup job, if the agent supports synthetic full backups, the differential backup job is converted to an incremental backup job.

  Note: The above-described backup methods do not apply to the Linux Client Agent.
