Hello,

I just setup GhettoVCB to backup our 2 VM's to a Synology Diskstation NAS using NFS.  The backup kicks off fine, and usually fails around 50-60% then goes to the next VM, and does the same thing.  I'm testing this at night when no other backups are ran and no users are in the office.  I've read that you can modify the NFS settings on the NAS to help, but I do not see any advanced settings on this NAS, just enable.

can you test copy the VM when off to the NAS, does it fail?

Test with Jumbo Frames enabled.

Jumbo frames enabled on the VM or on the NAS?

ESXi, network and NAS, failing at 50-60% would indicate a copy operation failure to NAS.

enable jumbo frames, test your NAS can handle the copy, change the datastore name to local datastore to eliminate network copy issue.

What do you mean by changing the data store name to local data store?  The NAS is already configured as a datastore on Esxi.

use a local datastore for the backup, and test

Backup to local data store was successful...I enabled Jumbo frames (4000) on the NAS, but it still failed.

so the issue lies with your NAS datastore, or network connection connection between ESXi server and NAS, or write speed of NAS. GhettoVCB scripts are working successfully.

Jumbo Frames are usually 9000 mtu, and must be enabled on NAS, network switches and ESXi server.

The switch is not a managed switch, so I probably won't be able to enable jumbo frames on the switch.  Do you think a USB attached drive would eliminate some of these issues?

USB could possible solve this issue, although slow in our experience.

a dumb switch is unlikely to handle jumbo frames.

Updating the firmware on the Synology Diskstation fixed the issue.
