Dotaz: Backup na sietovy disk (cifs), script

[xadam]

Zdravím Vás, Neviem či som už jeleň alebo ešte nie :o) ale mám problém napísať jeden backup script pomocou rdiff-backup ktorý má robiť inkrementálne zálohy na externý disk (cifs filesystem).

(os: debian lenny)

#!/bin/bash

#Cesty $source a $target
source="/"
targetDisc="/mnt/externalBackupDisc"
targetDiscFolder="/mnt/externalBackupDisc/incrementalBackup"

#Ako dlho udrziavat stare backupy
period="12W"

#excluded directory
e1="/bin"
e2="/boot"
e3="/cdrom"
e4="/dev"
e5="/lib"
e6="/lost+found"
e7="/media"
e8="/mnt"
e9="/new"
e10="/opt"
e11="/proc"
e12="/sbin"
e13="/selinux"
e14="/srv"
e15="/sys"
e16="/tmp"
e17="/usr"

#----

mount -t cifs //192.168.1.10/backupFolder $targetDisc -o username=backup,password=backup

rdiff-backup --exclude-device-files --exclude-sockets --print-statistics --preserve-numerical-ids --no-hard-links --exclude-special-files --exclude $e1 --exclude $e2 --exclude $e3 --exclude $e4 --exclude $e5 --exclude $e6 --exclude $e7 -
-exclude $e8 --exclude $e9 --exclude $e10 --exclude $e11 --exclude $e12 --exclude $e13 --exclude $e14 --exclude $e15 --exclude $e16 --exclude $e17 $source $targetDiscFolder

#Odstrani stare backupy
rdiff-backup --remove-older-than $period --force $targetDiscFolder

umount $targetDisc

Vždy skončím pri chybe:

Mas zvlastni styl psani skriptu. Co zkusit zalohovat jen to co chces napr. pomoci cyklu for. Nebudes muset excludovat 17 slozek. Jaky mas system? Jakou verzi r-b? Je updatovany? Ja pouzivam r-b ve verzi 1.2.8 pro zalohovani nekolika serveru a nemam s nim problem. Zkusil bych vyrazovaci metodu. Pustit r-b na jedne slozce, pripadne i s verbosity a sledovat, na cem vyhori. Pokud to spoustis cronem, doporucuju kontrolovat vystupni hodnoty z mount pro pripad, ze se nepodari pripojit disk, napr.

mount -t cifs //192.168.1.10/... || echo "Nepodarilo se pripojit disk"

nebo

if [ "$?" != 0 ]

Zahledl jsem "require_root_set". Nemuze byt problem s pravy?
