Are there any details regarding the improvements to the Deduplication Engine from Backup Exec 15 to Backup Exec 20? the statement "Backup Exec users can get improved speed, scale, and stability while backing up to the Backup Exec deduplication folder." from the BE 20.1 release notes is pretty vague. Is there any published data on the improvements?
Since upgrading to v20 I am seeing no deduplication improvements whatsoever, over the previous v15 system we had.
All I am seeing now is a server that has gone to 24/7 high utilisation, just doing a never ending task of checking the deduplication store, only pausing this when backup jobs run.
Improved compression ratios - No.
Higher throughput for backup, verification, cataloguing, duplication to tape jobs - No.
Improved deduplication store maintenance - No.
This was an in place upgrade, so the hardware has not changed. The hardware is a HPE Proliant DL180 G6 2 x E5540 quad core @ 2.53GHz, 24GB RAM, Win2K8 with a 12 disk SATA DAS through a Smart Array P411 array controller. It's managing a 6.4TB deduplication store (about 50TB of undeduplicated data). I know this hardware is old but it is getting no improvements where you state it will, with the new software.
