These data deduplication capabilities are available in the Backup Exec 15 Deduplication Option. Storage Efficiencies through Data Deduplication Backup Exec 15 includes advanced data deduplication technology that allows companies to dramatically reduce the amount of storage required for backups, and to more efficiently centralize backup data from multiple sites for assured disaster recovery. This additional layer of backup storage must be implemented wherever backups occur, including central data centers and remote offices. In order to maintain backups of critical data assets, additional secondary storage resources are required.

This is completely separate from the backup jobs that where run.TECHNICAL BRIEF: BACKUP EXEC 15: DEDUPLICATION OPTION. When you do a backup of a Dedupe folder to tape it will send over the segments to the tape. Dedupe only contains the segments that make up a file and the changes to that file.ī. For example, we B2D (with dedup) daily M-F, when I finally do the D2T portion, what might the size look like:Ī. So my question is what happens at rehydration of many backups. If you are backing up to Dedupe, you will not see the different versions on tape as the differnces are stored as segments, and the way the segments are put together will define the resulting output of the file/version you are trying to restoreġ. If you are backing up to disk (Not Dedup) then yes the different versions of a file will get duplicated to tapeī. Also, since backup-to-disk, might have several backups or versions of files, does this get reflected in the backup-to-tape?Ī.
You will have to duplicate to a dedupe folder then restore from thereģ. No you cannot restore directly from tape. Meaning, if I completely lossed the disk with the dedup'd data, that I can perform a restore directly from tape? Or does it have to be restored to disk first?Ī.

Yes, you do have a full copy of each server.Ģ. does this mean I have a full backup of each server on tape thenĪ. Let me go back and answer some of the questions directly, want to make sure I'm providing you an answer and I haven't missed any of your questions:ġ.
