Hello! I have a question about slow restore speed of virtual machine.
Backup speed of 8 VM (parallel) is about 900...950 GBytes per hour
Restore speed of one VM on VMFS through SAN is only 75...80 GBytes per hour.
A similar rate of restore observed when restoring VM to the physical backup host (HP Data Protector 7: "Destination" --> "Restore to Directory")
Why restore speed so slow and how to increase it?
VMware vSphere 5.0 Update 2 Enterprise (ESXi Build is 914586)
12 hosts (HP ProLiant BL460c G7/Gen8)
VAAI Supported and Active
10 VMFS LUNs, 2 TBytes each, Round Robin Multipathing
HP P6550 EVA with latest firmware (11001100)
FibreChannel, 4 Gbit/sec
HP MSL4048, LTO-5
HP Data Protector 7.0 Update 1 + Latest Patches
Physical Backup Host, Transport Method - SAN, LUNs in backup host disk management are "Online"
What is the speed of only one backup ? because when i see your stats you have 900GB/H for 8 VMs, So basically , one VM is around 100GB/H.
A restauration is always more slower that a backup job. So maybe your restore isn't really slower that it.
Otherwise, do you perform a backup and a restore in the same way? Backup and restore in LAN Free for example
