BackUp & Recovery

Münker — Fri, 12 Sep 2003 11:00:10 GMT

Hello,

I m in need to find a way to BackUp and Recover a Linux system. (I ???m missing HP???s IGNITE and make_recovery......)
I got a SuSE SLES8 running on a PC. Also I got a SureStore Tape running for writing the data on a tape. Using anyway a NFS- mount will also be no problem.

What I tried is using Norton Ghost. The Problem is the Linux-Filesystem which can??? t be compressed by Norton Ghost, so the Image ist very large!
Next try was to write a tar-archive which included all data via NFS mount to another PC. The Problem was to write back the data and to install grub.
Is there still a way to make something like a Flash-Archive under SOLARIS and write it back?

Best regards,

Juergen

Hi,

What you need is mondo rescue : backup (and compress if you want) to CD, tape, network... restore from the same...

As J??r??me I use mondo/mindi for this , and I also use dump 0 -f /dev/nst0

I mount fs read only

for all mount point ext2,3 fs from single user mode to tape.

Also use tar for none ext2,3 to tape
ex : tar cvf /dev/nst0 /dos

If I need to restore I use 1 cd of RH install in expert mode .

I have tested restore a few time to be sure.

hope this is what you need

Linux Backup and Restore
------------------------
Using tar
- used for creating archive files
- example
make archive + gzip compression:
# tar cvzf /var/tmp/boot.tgz /boot
extract files into a temp location:
# mkdir /tmp/untarred; cd /tmp/untarred
# tar xvf /var/tmp/boot.tar

Using dump/restore
- backup/restore ext2/3 filesystem
- support full and incremental backups
eg.
# dump -u -f
# restore -rf

just a note on using dump on linux 2.4+, you might want to check out this note from Linus Torvalds first :

Good one that ! Patrick

I will rewrite my cron/automatic backup script to use cpio or tar

The odds are to high for disaster recovery
