[Linux-bruxelles] Clonage de serveur

[eric hanuise]

perso j'utilise ce petit script maison poru els backups.
Quand je dois recopier un serveur, je fais une install sur le nouveau 
sereur et je restore ca dessus. Moyennant queklques adaptations, ca ce 
passe généralement assez bien.

(/home/backups/ correspond souvent sur mes macines a un share sur un 
serveur externe ou a un second disque dur dédié a cet usage)

backitup.sh

#!/bin/bash
# gnu tar syntax used here : tar -czv --atime-preserve --absolute-names 
-f [filename] [target] > [logfile]
# -c : create (replaces existing one if any)
# -z : compress using gnuzip
# -v : be verbose
# --atime-preserve : don't mess modtimes
# --absolute-names : keep root tree hierarchy
# --exclude [name] : exclude file or folder named [name]
# -f [filename] archive name
# [target] : file/folders to backup
# > [logfile] : send output to a logfile
tar -czv --atime-preserve --absolute-names --exclude backups -f 
/home/backups/home.tgz /home >/home/backups/home.log
tar -czv --atime-preserve --absolute-names -f /home/backups/initrd.tgz 
/initrd >/home/backups/initrd.log
tar -czv --atime-preserve --absolute-names -f /home/backups/bin.tgz /bin 
 >/home/backups/bin.log

/boot >/home/backups/boot.log

# now back up mysql databases

#etc...

# now backup all postgresql databases

touch /home/backups/completed
