Backup of VMs with space in the name seems to fail

I'm using Vertical Backup 1.1.1 towards a B2 storage. I run into problems backing up VMs with space in the name. Curiously, it seems that backing up VMs without spaces containing files with spaces in their names doesn't fail.

This backup, for example, is successful:

Creating a new virtual machine snapshot for NAS Uploaded file /vmfs/volumes/raid1tb1/NAS/CentOS 7 Template.vmdk Uploading file CentOS 7 Template-flat.vmdk Uploaded file CentOS 7 Template-flat.vmdk 98.91MB/s 00:44:10
Uploaded file CentOS 7 Template.vmx Uploaded file CentOS 7 Template.vmxf Backup NAS@stronger at revision 3 has been successfully completed

Both of these, however, fail:

Creating a new virtual machine snapshot for Quiz Maestro Uploaded file /vmfs/volumes/raid1tb1/Quiz Maestro/Quiz Maestro.vmdk Uploading file Quiz Maestro-flat.vmdk Uploaded file Quiz Maestro-flat.vmdk 138.05MB/s 00:31:38
Uploaded file Quiz Maestro.vmx Maximum number of retries reached Removing all snapshots of Quiz Maestro Command exited with non-zero status 2

Creating a new virtual machine snapshot for JBoss Test Uploaded file /vmfs/volumes/raid1tb1/JBoss Test/JBoss Test.vmdk Uploading file JBoss Test-flat.vmdk Uploaded file JBoss Test-flat.vmdk 5.20MB/s 14:00:54
Uploaded file JBoss Test.vmx Maximum number of retries reached Removing all snapshots of JBoss Test Command exited with non-zero status 2

This first one I have attempted a good half dozen times over two days with the same result, so it doesn't seem like an intermittent issue. Perhaps something in the storage of or creation of snapshot directories doesn't like spaces?

The 'Maximum number of retries reached' error was reported by the b2 storage backend, which should not have any connection to the name of the virtual machine being backed up.

Can you run vertical -vv -log backup "Quiz Maestro" to see if there are more information?

I made a log of a failing backup (with a space in the name): https://static.westergaard.eu/failing.log

I also made one around the same time and with the same parameters without spaces: https://static.westergaard.eu/success.log

The same pattern goes on for all my VMs (space fails, no space uploads successfully)

I was wrong. The name of the virtual machine is used in the path of the backup index file (for instance, the first backup of the virtual machine 'vm test' will be have an index file saved as 'snapshots/vm test/1'). The B2 storage doesn't like the spaces...

I'm working on a fix that should be available later today.

The new 1.1.2 build (sha256 is 7eef0446e503cd011d50d12d49378db692b1b3dc13ba5da83c5a31602a8654e3) should fix this bug.

Yup, now it works. Thanks for very quick action!
