An existing snapshot is no longer valid and cannot be mounted for subsequent operations(1542)

[XTREM1337]

I received an error during my Exchange backup

'' An existing snapshot is no longer valid and cannot be mounted for subsequent operations(1542) ''

I thought that I just need to delete the snapshot below and relaunch a new fullbackup, but I did not find the snapshot in the directory, even on the staging disk.........

Critical bpbrm(pid=6056) from client CAIJ-EXCHANGE: cannot open C:\Program Files\Veritas\NetBackup\online_util\fi_cntl\bpfis.fim.CAIJ-EXCHANGE_1348331387.1.0 

How I could resolve this issue ?

See the screenshot.

What version are you running?  What kind of Exchange backup is this (DAG/CCR/?)?

from a command line:

bpfis query

This displays any acive snapshots created by bpfis

You can then use:

bpfis delete -id snapshot_id_found_above

but you need to try and find out why it happened

also check VSS  using "vssadmin list writers" as  you may need a reboot anyway
