Title: Restoring individual files in SME 6.X
Post by: ralphd on October 08, 2004, 09:10:47 PM

Hi everyone,

I'm looking to restore an individual file from a backup created on an SME 6.0 server.  The DMAY contrib for advanced restore procedures doesn't seem to work and I think it has to do with the method the backup is running in SME 6 has changed from 5.X.  (i.e. Tar vs dump???)  

Someone mentioned that it might be useful to mount the drive.  

Any ideas?

Thanks,

Ralph

Ralphd,

Here is skinny on how to get this to work.

edit /sbin/e-smith/RestoreNow and replace with the following:

<snip>
#!/bin/sh

#------------------------------------------------------------
# copyright (C) 2001 DMC NETSOURCED.COM
#------------------------------------------------------------

export PATH=$PATH:/sbin

#-----------------------------------------------------------------------
# modified by John H. Bennett III  bennettj@thebennetthome.com
#
# The below 2 lines remove the spaces from the /tmp/RestoreNow file.
# If the spaces are not removed, then the restore will begin restoring
# from / and try to restore everything, which breaks your system.
# I know this from first hand experience
sed  '/^$/d' /tmp/RestoreNow > /tmp/RestoreNow1;
mv -f /tmp/RestoreNow1 /tmp/RestoreNow;
# end modifications by JHB3
#-----------------------------------------------------------------------

cd /
/bin/mt -f /dev/nst0 rewind
/bin/mt -f /dev/nst0 fsf 1
/usr/bin/flexbackup -extract -flist /tmp/RestoreNow
/bin/mt -f /dev/nst0 rewind

</snip>

Then edit /etc/e-smith/events/actions/BackupNow and change /sbin/e-smith/backup to /sbin/e-smith/do_backup

Now you should be able to use Darrell's old RPM to do immediate backups and restores.  One note:  When you do a restore, for some reason, the tape stays active after restoring the file.  I don't know how long the tape will stay active, because on my system, once I see that the file has been restored, I reboot the system.

Good Luck to you.

 I'm new to SME and Linux and still figuring it out so forgive me. I looked at do_backup.. It looks like it actually starts the backup process agian.. that may be why the drive is active... is there a diffrent event that can be called? Or am I missing something here? if so please explain.
