Answer / saurabh singh

Here i mention the SUN solaris technique of taking backups.

First u know which FS are mountable and which are
unmountable.

Unmountable includes: /home , /var , / , etc here i means
all partitions created on HDD .

Mountable : cdrom , flash etc..

use these command to take backup in solaris 10
mount /unmount than use these command .
UFSDUMP : it is one technique

and

FSSNAP : for unmountable partitions.


If you are talking abt backup tool than see AMANDA it is
good.

1. Full Backup or Snapshot only --> Backing up everything
2. Incremental Backup --> Backing up everything since last
changed on full backup.
3. Differential Backup --> Seems to be another name of
Incremental Backup.
4. Hot backup --> On the fly taking backup. [ /etc/hosts,
/home/ nic cards conf files and dbf files ]
5. Cold Backup --> Taking backup after stopped the services
on the server.
6. Dump Backup --> Backing up everything on storage media
like say tape, CDs or etc.
