Solaris Zones and Networker
I have Solaris 10 Sparc (8/07) with non-global zones and Networker 7.2.2.
I need to backup those non-global zones and would like to have your experience and opinions on what would be the most preferred way for networker - backing up global zone and each individual non-global zone. All I can think of now is if I only back up global zone, I will need only one license and more for non-global zone. As I searched on the forums, I found several posts but still couldn't determine what may be the better route.
I would like to know if there are any issues, pros and cons, problems on global zone vs non-global zone for networker 7.2.2.
Thank you.

You CAN backup non-global zones from global zone. In example let's assume that you have two non-global zones: z1 and z2 with zone_paths set to /zones/z1 and /zones/z2. All you need to backup is /zones/z1 and /zones/z2. But ...
1. You have to ensure data inside /zones/z[12] is consistent - especially when you have application running inside non-global zone (shut down the application, or shut down the whole zone). Generally it's gonna be a better idea to use client (and proper NW module) installed inside non-global zone to backup application (Oracle, Informix, DB2 ...) data - in that case 7.2.2 is not supported.
2. If your zones are using inherit-pkg-dir ensure that you do not backup it twice. In example: your z1 is configured to inherit directories:
zonecfg:z1> info inherit-pkg-dir
inherit-pkg-dir:
dir: /lib
inherit-pkg-dir:
dir: /platform
inherit-pkg-dir:
dir: /sbin
inherit-pkg-dir:
dir: /usr
ther is no need to backup /zones/z1/root/{lib,platform,sbin,usr} if you are backuing up /lib,/usr,/platform,/sbin from global-zone
3. if your non-global zones using other directories mounted via lofs from global-zone ensure that you do not backup it twice.
4. When you are performing backup from global-zone always recover from global-zone.
