Hi,
I have be 2010 R3 SP4 installed in a Windows 2008R2.
My file server is vm esxi 5.5 windows 2012 with deduplication enabled to save space in disk. I use this feature on windows because I don't have license for dedup with be.
My disk for file server have 900GB and deduplication has a rate of 38%, saving 535GB. This disk is a RDM disk in equallogic storage.
The problem is that backup is so slow. A full backup started on friday night and today(monday) don't finished.
I did several tests:
SERVER01 old file server windows 2008R2 Folder with 35GB finished in 0:49:33 997.00 MB/min
SERVER02 current file server windows 2012 Folder deduplicated with 35BG finished in 1:26:50 460.00 MB/min
Backup to Disk
SERVER01 old file server windows 2008R2 Folder with 35GB finished 1:13:55 677.00 MB/min
SERVER02 current file server windows 2012 Folder deduplicated with 35BG finished 1:52:00 420.00 MB/min
SERVER02 add new disk with 100GB RDM without dedup enable. Folder with 35GB finished 0:48:20 1.058.00 MB/min
The folder used is the same to all tests. Looking the tests the problem should be in backup dedup files.
Are any configuration necessary to optimize backup of dedup files?
Does BE 2010 R3 SP4 support windows 2012 dedup file?
