VSSADMIN List Writers

Backup faild due to WMI Writers error

Retrayable error

In My setup, always asked o run command VSSADMIN LIST WRITERS. If no errors found then no issues in taking backup but if error occurs in any of the writers then we need to troubleshoot it. But i really didnt understand VSSADMIN

1.What it is ?
2. How it works?
3. Why Backup failed if this failed
4. How to troubleshoot if any of the writers failed.

Kindly explain the working or give a solution to learn it with a proper understanding of VSS please.

Ah i see backup clients in a vm enviroment.

VSS needs someone who cares of doing the shadowcopy of inaccessfiles. That are the list writers. I was in the same situation with the two problems backup exec vss writer or vmware vss writer.

My solution was to use the backup exec one and deinstalled the vmware one. Both are installing VSS writers. But is depending when you install which who will win.

3. Backup is failing if you want to backup files that they are in access in the moment of backup.
4. Check which one is used and use only the one from your backup programm
