ghettoVCB fails to make backup of VM containing special character(s) in VM name. #160

Hello, Thank you so much for such an easy-to-use backup script. I found ghettoVCB fails to make backup in case VM name has a special character "+". I guess some other characters may cause the same error. Regards,

HI, I can confirm this problem with the characters [ and ] in vm names. VMware ESXi 6.5.0 build-10884925 GhettoVCB-version: 2019_01_06

could we please have details of how it fails? I have a failure scenario I am attempting to troubleshoot and I have "-" in the vm name. The failure is "Snapshot timed out, failed to create snapshot: "ghettoVCB-snapshot-2019-06-08" for imap-plus-1". It takes 15.20 minutes for the failure to ocur.

There are no pre-existing snapshots of the VM. Backup works fine when the VM is powered off.

So, is this symptomatic of the error?

Any other place to look for troubleshooting help?

Hi, I have the same issue and a hard time figuring out what is going on as there is no detail (debug enabled).

Any help would be highly appreciated!

Update: it looks like it works with another VM. I will need to figure out why it works with some and not with others.... Will update once I have more clarity

Yup, you may want to see if the VM has had any old snapshots or that it couldn't be consolidated or potentially even on a datastore that doesn't have enough space. Since the snapshot can't be created, there's no much more the script can do and you'll need to investigate your env

Yes, found the issue for the vm I used for testing. It had a passthrough device hence snapshots are not possible.

Works on all other VMs now. 👍
