Re: [Veritas-bu] "/" + Cross All Mnt Pts Vs. ALL_LOCAL

I much prefer the method you’re considering using vs what you’ve been doing.

Each filesystem gets its own job. One fails, they don’t all fail, and you know just what to re-run. Reporting is very nice as well.
Multistreamed backups = multistreamed restores, even if you only allow one backup to run at a time. (ALL_LOCAL_DRIVES + Allow multiple data streams + max jobs per policy or client set to 1) and multistreamed restores are good.
No need to use the NEW_STREAM feature except under extreme circumstances, like one filesystem that’s HUGE and can’t be backed up with one stream.

Subject: [Veritas-bu] "/" + Cross All Mnt Pts Vs. ALL_LOCAL_DRIVES

I'm just looking to see what the recommendation out there is for backing up unix-based servers.

In the past I've always backed up a unix client using "/" in my selection list and using cross all mount points + exclude lists. As I was browsing through the Admin guide I read that ALL_LOCAL_DRIVES could be used on unix-based clients as well.

I'm interested to know how people out there backup their unix clients. We use cross all mount points so to make sure that an Admin doesn't create something on a client that needs to be backed up that he doesn't tell us [backup admins] about.

I'm looking into using the ALL_LOCAL_DRIVES directive with "allow multiple streams" so I can stream out my unix clients by filesystem thus getting more i/o throughput by having the backups read from multiple physical disks at the same time. ... This opposed to using "/" + NEW_STREAM .. since I don't really know what directories are actual filesystems. (I don't admin the majority of the clients I backup.)

Thanks,
