Neither bprd nor bpdbm are running. Probably because the subfolders under /usr/openv/netbackup/db are gone.
I am not sure if creating empty folders will be enough, but probably worth a try.
Please remove the symlink and create the db folder in /usr/openv/netbackup/.
Create all of these folders in db:
- class
- client
- config
- error
- images
- jobs
- media
In images folder, create empty touch-file: db_marker.txt
Create bprd and bpdbm log folders under /usr/openv/netbackup/logs.
Stop and restart NBU.
If bprd and bpdbm are still not starting, look at the relevant logs for clues.
Probably best not to spend too much time on this and rather uninstall NBU and re-install.
You should be able to recreate the dr-file and then recover the catalogs.
PS:
Were all of your MSDP backups duplicated to tape?
If so, Catalog recovery will be good. Further steps will be needed to remove the catalog info for dedupe backups so that only information about tape copies will be left.
