restoring vmware servers to different datastore VMFS version and block size

Daryl,

good question which i would also like to know the answer..

i would perfer to test it and see how it works... also we can check with VMware experts if the restore works for Different version and and block size.

if it works when vmware do it from their local backup... mostly it do also work from netbackup.. worth testing...

the source is  8mb block Size vmfs 3.46 and we can only restore so far to that

i have tried restoring to 1MB block size vmfs 5.54 and it fails before it starts writing

the LUNS that are 1MB block size vmfs 5.54  are presented to the media server (backup/restore host)

hi, Daryl Gawn

Could you please provide further info regarding your environment?

Which version of NBU, vCenter, ESX server?

Which transport mode do you use during full VM backup and restore?

 

I setup an envrionment similiar to yours and it can restore normally.

vCenter: 5.1 | ESXi 5.1, VMFS 3.58(SAN storage), VMFS 5.58(SAN storage) |

NBU: 7.6.0.2, separate master/media/client, nbd mode for backup and restore

Thanks

 

hi Walker Yang

i managed to restore to another datastore that is 1MB block size vmfs 5.54  , i suspect something isnt right with the original 1MB block size vmfs 5.54  datastore i was using

so it is working ok

i would still like to know if there are any technotes or combatibility tables on this topic though

 

You say the source was '8mb block Size vmfs 3.46 ' - but what version of ESX/patch level was it running?

 

This is worth knowing, but may be unrelated:

Page 15 of the NetBackup VMware compatibility doc:
http://www.symantec.com/business/support/index?page=content&id=TECH64542
...says that v7.6.0.2 (and v7.6.0.1 with EEB EEB3318872) was built with VDDK 5.5.

The VDDK 5.5 Release Notes:
https://www.vmware.com/support/developer/vddk/vddk-550-releasenotes.html
...doesn't list support for anything below vSphere v5.0U3.
