E un script simplu pentru archiva un director
#!/bin/sh
# director de backup,sursa si tmp
BUPDIR=/backup/
SRCDIR=/var/www/html/
TMP=/tmp
# retine cite fisiere ?
KEEP=2
##############################
PATH=/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/mysql/bin:/root:/etc
# current date
DATE=`date +"%h_%d_%Y"`
# filename
FILE="${BUPDIR}nume-fisier-${DATE}.tar.bz2"
# backup
tar -jcf $FILE $SRCDIR >/dev/null 2>&1
if [ `ls -1 $BUPDIR | wc -l` -gt $KEEP ]; then
i=
for each in `ls -1t $BUPDIR`; do
if [ $i -gt $KEEP ]; then
rm -f -- ${BUPDIR}/${each}
fi
let "i = i + 1"
done
fi
echo "done"

E OK scriptul, foloseam si eu candva de mult din astea DAR ;) vezi ce stie "rdiff-backup" ( http://rdiff-backup.nongnu.org/ ), cred ca o sa-ti placa.

numai ce am impachetat ptr mib fwbackups
http://mib.pianetalinux.org/mib/quick/basic-rpms/mib-rpms/777-fwbackups-...
ia vezi ce stie ala .
io ramin al dd-ul meu , care nu l-as da pe nici un alt tool :p
faceti voi cu tools-uri si scripturi .....ghghghghgh
ascultati la mine
dd +testdisk+photorec si alceva ptr backup&recovery nu va trebuie .
@csaba
esti cam fixat cu : "....over a network........" :p
guru retelelor , vezi mai is si alte chestii in afara de retelistica :p ghghghghgh
Unix is user-friendly. It’s just very selective about who its friends are
dd e fain, daca vrei si MBR. Daca nu ai de gand sa strici MBR, rsync RULEZ, vorba rusului. Cam in genul 'rdiff-backup'. Mai ales ca azi spatiu' de stocare e relativ ieftin.
de ex., eu folosesc pt. / backup:
[code]su -
rsync -abv --delete --delete-excluded --exclude="/sys/**" --exclude="/proc/**" --exclude="/dev/**" --exclude="/home/" / /mnt/backup[/code] --exclude="/home/", daca e partitie separata. Merge inclus in cronjob.
Restore se poate face pe un sistem care nu ruleaza (de pe un live, de ex.), inversand sursa cu destinatia:
'rsync -av /mnt/backup/
Avantaju' ar fi viteza. Bun si la defragmentat ext4 :)
rdiff-backup de fapt se foloseste de rsync sau se bazeaza pe el, doar ca ofera cateva optiuni specifice de backup mai faine decar rsync-ul chel ...

Si daca tot vorbim de backup-uri, iata 2 articole interesante peste care am dat intamplator astazi:

Astazi am implementat un sistem de a salva tot ce este necesar din serverul de la servici catre un folder montat CIFS de pe un network storage Edimax NS-2502 (mai multe despre acest NAS veti gasi pe blogul meu in zilele urmatoare).
Nota: am observat ca rdiff-backup este destul de lenes ca atare, asa ca scriptul ruleaza pana in 10 procese de rdiff-backup si asa maximizez mai bine banda de transfer. Serverul pe care ruleaza este un IBM cu 2 procesoare Xeon quad-core.
