Backup sets
A backup set is a collection of the data that you back up from a single source of content. A single source of content can be a server or a Microsoft Exchange data set, for example. If you select multiple sources of content, Backup Exec creates multiple backup sets. When you run a backup job, Backup Exec creates the backup sets and writes them on storage. To restore data, you select the backup sets that contain the data that you want to restore.
Backup Exec keeps the backup sets that are stored on disk storage and disk cartridge media for as long as you specify in the backup job properties. By default, the amount of time that backup sets are stored is based on the type of backup job and its schedule.
For example, you can specify to keep the backup sets from a full backup for two weeks on a disk-based storage device. After two weeks, the backup sets expire and Backup Exec uses the data lifecycle management feature to delete the backup sets and reclaim that disk space. If you later create an incremental backup job, Backup Exec keeps the full backup sets for two weeks, plus the amount of time that it keeps the incremental backup sets. If you keep the incremental backup sets for four weeks, then Backup Exec keeps the full backup sets for six weeks. The data from a full backup job is kept as long as the data from its associated incremental backup jobs. Backup Exec does not reclaim the disk space for backup sets from a job that depends on another job until the data retention expires for all of the associated jobs. Even if the backup set is displayed as expired, the data is available until all dependent backup sets expire as well.
Backup Exec manages the retention of backup sets differently depending on the type of storage to which you back up the data.
Table: Storage types and backup set retention
Type of storage | Backup data retention |
---|---|
Disk storage, disk cartridge devices, deduplication disk storage, storage arrays, cloud storage, and virtual disks | Backup Exec uses data lifecycle management to automatically delete expired backup sets from disk-based storage. By default, Backup Exec keeps the most recent backup sets that are necessary to restore any backed-up component of a server, even if the backup sets expire. Even if the backup set is displayed as expired, the data is available until all dependent backup sets expire as well. For disk-based storage and any disk cartridges that you reattach to the Backup Exec server after a specified number of days, you can prevent Backup Exec from reclaiming that disk space. A global setting limits Backup Exec to read-only operations on disk-based storage or a disk cartridge if it has been detached for a specified number of days. You can also limit Backup Exec to read-only operations per disk storage or disk cartridge by enabling the setting on the device properties. See How data lifecycle management (DLM) deletes expired backup sets on disk-based storage. See How to restore data from a reattached or reinserted disk-based storage device. |
Tape cartridge media | Backup Exec uses the Advanced Device and Media Management (ADAMM) feature to manage data retention on tape cartridge media. ADAMM expires the backup sets that are stored on media according to a set of rules that you apply to the media. Backup sets are not automatically deleted from tape cartridge media, but they can be overwritten, depending on the rules that you specify. The set of rules that manages tape cartridge media is called a media set. You create media sets that specify append periods, overwrite protection periods, and vaulting periods. |
You can perform the following actions on backup sets that are on disk-based storage:
Change the expiration date of backup sets to keep them longer or expire them immediately.
Extend the amount of time that you keep backup sets by retaining them.
Release any backup sets that are retained to let them expire automatically.
For all backup sets, including those on tape cartridge media, you can perform the following actions:
Catalog backup sets so that you can view the data that is contained in the backup sets and search for files to restore.
View the contents of backup sets and browse the backed up data that is contained in them.
View the system properties and job properties of backup sets.
