Frequently we get asked how to implement a backup strategy that you have used to employ with your old backup product. The requirements (which you are used to):
How can this be achieved? Create the following backup plan:
Backup Plan > Additional Options > Volume Use: Use new media Backup Plan > Additional Options > Retail data for: 10 days In the media pools used, the following option must be set: Media Pool > Additional Option > Recycle policy: When expiration date is reached Create two media pools, one for the Full backup and one for the Incrementals. By employing a separate media pool for the full backups, it is easier to distinguish the full from the incremental tapes and it also allows you more flexibility in replacing the tapes in the library. By using a separate full backup pool, you can replace the full backup tape(s) against the other set at any time during the week, e.g. on Mondays, without having to worry about them being overwritten by the incremental run. With a single pool for both full and incremental backup, you would need to replace the tapes on the day before the full backup. By configuring the plan this way, you will remove the tape last written with the increment every day and replace it with another one. This means, you need a total of 5 tapes (assuming your increment fits on one tape) in the Incremental pool. To easily identify the last written incremental tape we suggest the following handling:
In case of an upcoming holiday, place as many incremental tapes as are required into the library, to cover the duration of the holiday. Please also see the following white paper on progressive backups: http://support.archiware.com/support/download/ProgressiveBackup.pdf | |
