I guess you question is both too wide and lacking information about your specific goal and constraints.

Backing up depends on a lot of factors, and is not fundamentally different with Solaris compared to other O/Ses.

On important point often overlooked is the restore phase, you'd be surprised to know that a substantial part of back-ups done do not allow to properly restore what they are supposed to.

:study: first you should read about it in solaris basic admin for normal backup which can make backup with #tar cvf for regular files and another way of backup is for file system you can find it in Solaris advanced admin. by using #ufsdumpcommand.

Examples:

Back up a directory into a tape:
tar cvf /dev/rmt/0 /export/home
ufsdump 0uf /dev/rmt/0 /export/home

View the files in the tape:
tar tvf /dev/rmt/0
ufsrestore tvf /dev/rmt/0

Extract the files:
tar xvf /dev/rmt/0 /export/home
cd /export/home ; ufsrestore rvf /dev/rmt/0

Ufsdump backs up ufs file systems, tar does it by directories.
