We don’t use ALL_LOCAL_DRIVES on our Unix and Linux systems.  We specify / (root filesystem) for our OS backups then use exclude lists to leave out the things we don’t want.  Usually our databases and applications have their own policies starting at their mount points OR aren’t backed up because they are test/dev and our policy is to refresh them from Production backups if they have issues.

 

It may be the reason you’re seeing the messages is that “ALL_LOCAL_DRIVES” is essentially being seen as “all mount points” by NBU so it first backs up / and gives the error from / perspective then moves on to /boot then /var etc…

That is it may be NBU behind the scenes is doing:

/ backup – complains about all submounts not part of / itself

/boot backup

/var backup

 

You might test that theory by create a small submount of one of the others e.g. /var/test then see if you get complaint about /var/test not being part of /var (as opposed to not being part of /).

I get all those same warnings on redhat hosts whether I’ve got cross mount points selected or not… I’m using ALL_LOCAL_DRIVES so it does appear to be backing stuff up, as I do have data in /boot and one or two others it’s complaining about…

The messages seem to indicate you have deselected “Cross Mount Points” in the policy.    Have you checked that?

 

It is saying it didn’t back up these items as they are on separate mount points.   If you do “df –h” on the Linux host it should show you what mounts exist.

 

We actually had an issue here recently on 6.5.4 where we found something had caused that to be deselected in several of our policies.   We think it was due to an attempt to manually edit the policies from command line a few months back.   At the time that happened it caused other issues as well.   Apparently there is a checksum NBU stores internally for what is in the policies so it didn’t like that manual modification.

 

Also FYI: 

We typically add /net, /sys and /proc to our exclude lists for Linux.  /net is a shortcut to NFS mounts so unless you intend to back them up via /net probably good to exclude that.  /proc and /sys aren’t actual disk filesystems so can’t be backed up – attempts to do so typically result in a status 1 rather than status 0 on your backup.

Hello Folks,

 

Below is my netbackup environment:

 

Master - Solaris 10 , Netbackup 7.0.1

Media - Solaris 10, Netbackup 7.0.1

Client - Suse Linux 2.6, Netbackup 7.0.1

 

Backup for the client is completing with status code 0 but in the detailed status its showing below warnings

 

Mar 24, 2011 8:00:23 AM - Info bpbrm (pid=12275) from client whplmoscyc1: TRV - /share is in a different file system from /. Skipping.

Since we upgraded from 6.5.3.1 to 7.0.1, all unix backups are showing these warnings but are completing with status code 0.

 

I googled for the error but not able to find a suitable answer for it.

 

Can anyone please explain why is that so?

 

Thanks in Advance,

 

Saran
