Support Knowledge base How and when to reclaim space from within a Deduplication Storage or Deduplication enabled cloud storage in Backup Exec. Article: Last Published: Ratings: 6 Product s : Backup Exec. At 95 percent it is recommended to stop the Backup and first reclaim some space Step 3 - Review the Catalog Logical Size section as well in the above command output. To check the status of the command that was run two times use the following command : crcontrol.
Step 4 - Rerun the crcontrol. Related Knowledge Base Articles Backup Some expired backup sets are not being deleted after the expiration date or unable to overwrite or delete the last backup set.

This is due to the fact that Backup Exec cannot read the content of the data stream sent by these systems and therefore cannot split it into chunks. If the chunk is already present in the deduplication storage on the backup server, the source agent drops the packet and only a pointer is created on the backup server. So only unique packets are sent over the network. Since this game of questions and answers takes a while, the first run of a backup job may be quite lengthy.
During subsequent runs of the same backup job, the backup server sends the remote agent a blob of information, containing the answers of all questions he asked during the last run. This means that from the second run on, the amount of data sent over the network is massively reduced, resulting in less need of bandwidth and smaller backup windows. Nevertheless, as in so many things in IT, this technology also has a downside: The source server has to meet some technical requirements:.
Among other things, this technology enables the Backup Exec server to control and monitor the deduplication process on the appliance. When using Backup Exec together with a OST appliance, the appliance does the deduplication work and just reports to the backup server, so Backup Exec can keep its catalogs and database entries up to date.
Another one is the huge performance these appliances deliver during backups as well as during restores. The most important disadvantage however is the fact, that Backup Exec handles OST appliances similar to tape devices. This means that GRT restores cannot be done directly but rather require a staging process and therefore enough local disk space on the backup server to restore the whole container file.
The process of copying or duplicating data from one deduplication storage to another one, is named Optimized Duplication. BEDAT is designed to be as simple and as easy to use as possible.
It is a wizard-driven utility that does not require any specific IT expertise to use successfully. However, a PartnerNet account is required in order to access and download the tool. It supports estimating deduplication results for file system data, Exchange data, and SQL data. You must be a registered user to add a comment. If you've already registered, sign in.
