Re: [ADSM-L] Help with DFS backups

Zoltan

Have you tried explicitly including each DFS share as a mount point?

I've had to do something similar in the past, though I can't remember
exactly whether I used the "DOMAIN" "INCLUDE" or BOTH statements.

Sorry, that's my best effort - though I would like to hear about the
solution you end up with.

Best regards,
