Just finishing setting up restore and backup via san mode. Had some issues with restore, because of lun's were write protected on my proxy server, which is windows server 2012R2, because of default san policy.
Anyway, the restore of an entire VM with only 1 restore point, was slow, around 77 MB / sec. Tried Hotadd, which was faster, around 90 MB / sec.
Here is the really weird part. Server is 2012R2 running storage spaces, 12 disk presented as jbod without raid controller, SATA 7,2K Mirror with deduplication. CPU is xeon something with 4 cores, and 32 GB memory. Now, i am copying a file internally on the server, from the V: drive (for veeam
) to the C drive, which is a SSD disk (in mirror on another controller)
Copying a VBK file from the backupupjob folder called "DirectSan_test_Hostingtest" to the C: drive, i get a speed rating around 30-130 / sec. (size is around 30GB) Copying some VIB files from other folders around 17 GB in size, i get speed around 500-700 MB pr. second which is as expected. And some of the other VIB files from some of the other backup jobs are REALLY slow just copying internally from V: to C: and some are extremely fast.
Volume is NTFS, formatted in 64 KB cluster size, and formatted with the option for large drives.
This does not make any sense to me, is something fragmented, and maybe some of the chunks are placed randomly on the volume, and maybe some are aligned up nicely?
Settings in veeam for storage is local target, and optimal compression.
In veeam, i am not using the option for "Align backup file datablocks"
