Solaris

dear friends,

i am not a expert in solaris 10, i want to practice backup software . where from i can download backup software free . (EBS, legato or any )

please help me

Does solaris still pre-package ufsdump? If so, it's quite a useful tool. However, it doesn't have many of the modern features, such as file-indexing, point-in-time recovery, true distributed awareness (use machine A to backup machine B to a tape on machine C).

What's free? You often see ads here for Zmanda, based on Amanda. There's also Bacula, which has an excellent architecture, but stores files rather clumsily in a database (perhaps its improved in the 6 years since I've set it up).

ufsdump/ufsrestore is solaris native command to backup/restore. Its good to try that too as otheus suggested

ufsdump/ufsrestore is native and works well for ufs file systems. Amanda uses the native tools, so they fit together just fine. If you want to do file system snapshots before doing ufsdump from within Amanda, see http://wiki.zmanda.com/index.php/Bac...yk.27s_Example.

However, if you are using zfs file systems, the game plan changes. ufsdump is not applicable. There isn't what I would call a perfect solution, but with Amanda, you have options. See Comprehensive Backup and Recovery for ZFS filesystems Zmanda Team Blog. I really like zfs, and have set up a J4200 with raidz2 and hot spares quite easily. But then I had to decide how to deal with backups.

I would recommend starting out with the UFS tools. Solaris comes with three nice utilities to manage UFS backups.

fssnap is used to take moment in time images of a file system that can be mounted read only or backed up with ufsdump.

ufsdump backs up a UFS file system to a file you specify

ufsrestore restores a filesystem from a dump file
