Solaris

I have done it many times, have never had any issue. Maybe I'm lucky
my practises don't show any difference exept that exceptions mentioned on my previous post.

The issue is not that much files created in backup time are not included but about overall consistency. Files can be removed, renamed or have their content modified during the backup. Unpredictable behavior may result with a system restored from such a backup.

hi all;
if i want to take full image from my hard disk and restore it again to another hard disk
what is the step to do that
this is my hard disk
/dev/dsk/c1d0s0 mount /
/dev/dsk/c1d0s1 mount swap
/dev/dsk/c1d0s7 mount /export/hoem

there is more then one solution for this...

1. boot your system from a cd/dvd and use "ufsdump/ufsrestore"
2. create a flasharchive from your system (read "man flarcreate")
3. create a software mirror of your disk with slvm
4. you can also use "liveupgrade" to make a full copy of your existing disk

the solution you should choose depends on your requirements! (system can/can't have downtime; the new disk is/isn't in the same machine; ...)

1. #format (check availability of HDD in system)

2. #prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/cxtxdxs2 (if they are in same size)
3. #newfs /dev/rdsk/cxtxdxs0 (setting up File system)
4. #mount /dev/dsk/cxtxdxs0 /mnt (mount corresponding sliice on which copying will accomplished)
5. #ufsdump 0f - /dev/rdsk/c1t0d0s0 | (cd /mnt && ufsrestore rf - )
6. #umount /mnt
Steps 3-6 will be repeated for each slice
7. # installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/cxtxdxs0

of course this is only one way u can do that. as DukeNuke2 said it depends on your requirements

thats all .. enjoy )

good luck

very thanks for your effort helping me in this backup solution

The ufsdump man page very clearly tells you not to do a dump against a read/write mounted file system.
