VMware Data Recovery Backup Speed

Hello all,

I would like to know why it takes between 3-5hrs for VMware Data Recovery to backup a VM with a 40GB .vmdk?

Here is the VMware Data Recovery setup:

3 x ESXi 4 Update 1 hosts

1 x IBM DS3400 Fiber Channel SAN (8-disks RAID-10 array for VMFS)

1 x vCenter 4 (physical server)

1 x Buffalo Linkstation Quad (NAS)


using CIFS share with 3.9TB mounted to the VMware Data Recovery VM/backup server

I use a custom backup retention policy to preserve at least "2" most recent backups, as well as the most recent backup from each of the last.

I believe VMware Data Recovery will do INCREMENTAL with De-Duplication, so shouldn't the backup go much quicker since it is incremental or does de-dup slows it down?

Any advice on how I can speed up the backup process will be much appreciated.

With this configuration, my only guess is the CIFS share. Try not making it bigger than 500GB (as per VDR documentation). The de-duplication process usually uses a lot of resources on the VDR VM, so you can also try to increase the CPU number/memory for it and/or make a good CPU/memory reservation.
