Backup fails - Error code 3923 can't access device /dev/disks/UUID

I downloaded the latest version of xsibacup DC today and tried on ESXi 7.0 free but got the below error

The backup command is as below

/vmfs/volumes/ESXi/XSIBackup-DC/xsibackup \
--replica \
"VMs(JP-PANOPTA)" \
"/vmfs/volumes/VM/VMBackup" \

/vmfs/volumes/VM is internal datastore. We tried with NFS datastore but experienced the same error

Please provide the output of this two commands:

ls -la /vmfs/volumes/
esxcli storage vmfs extent list

Your output is normal.

You are running (c)XSIBackup from a datastore named "ESXi" which is a reserved word to (c)XSIBackup.
Please, install to the recommended location (/scratch/XSI/XSIBackup-DC) and try again, just to clear some variables.

Although that should not cause any problem, there's a possibility that the keyword is causing some conflict in some inner algorithm, we'll dedicate some time to revise disk selection algorithms.

Also, check that we have tested the (c)ESXi version you want to install to before doing it.
https://33hops.com/xsibackup-vmware-esx … -list.html

UPDATE:

The above are just general considerations and a move to narrow the problem down.
Please, provide the output of the commands:

vim-cmd vmsvc/getallvms
vmware -v

So that we can try to reproduce your issue as closely as possible. The purpose of vim-cmd vmsvc/getallvms is to retrieve the DS name your VM is sitting at.
If you don't want to publish your real output here, please mask it down and send the real one to our support department.
If it is due to some bug we will release a quick fix

Please download latest version and let us know if that fixed your issue.

We will try the suggested version and update later

Hi Team,

This issue seems resolved with the provided release.
We will continue to monitor the status and let you know if there are further issues

admin · 2021-08-18 11:08:00

Thank you for your feedback. You can safely use that version, it contains a tweak in comparison to 1.5.0.13 and will become 1.5.0.14 as we eventually add some additional tweak or fix.

Thanks a lot for your great support!
