Updating catalogs symantec backup exec
Depending upon various factors, you might find that your catalogs folder grows very large.
It's not unusual for it to grow to several gigabytes.
Before reading on, you may wish to read What are catalogs?
The first factor is probably something that you don't want to change just to reduce your catalog size.
How long you wish to retain the catalogs for is something you can change, depending upon your requirements.
To reduce the size of your catalogs, you can reduce the truncate period and the removal period. Bear in mind that as you decrease these, you increase the likelihood of having to catalog a tape before you can restore from it.
Students also learn how to configure and work with various Backup Exec Agents, which protect applications like Microsoft Exchange, Microsoft Share Point, and Microsoft SQL.
The course also covers the Virtual Environment Agents and the Deduplication Option.
Backup Exec is supposed to clear (prune) expired data on a regular basis but the process can mess up more often than not.
The end result is you can run out of space on your media even though your jobs are set to “overwrite” older media.
The biggest cause of this kind of problem is inconsistent results with full backups.
Backup Exec will NOT delete old data sets, even if they are expired, if more recent full backups have not been successful nor will it let you overwrite those media sets.
