[SOLVED] Cron Backup

[Ihyae]

Salve a tutti,
sono nuovo al forum ma uso zeroshell da un po’.. ultimamente si è presentata la necessità di schedulare un dump della cfg su un server remoto..

Ho dato un’occhiata agli script presenti nel path: /root/kerbynet.cgi/scripts/

e ho visto tramite console che invocando il backup dalla pagina web, viene lanciato il seguente comando:

/bin/sh /root/kerbynet.cgi/scripts/backupdb /udev/hda3 _DB.001 Yes

ho provato a modificare la riga 60 dello script: /root/kerbynet.cgi/scripts/backupdb in questo modo:

tar cfzv - --exclude var/register/system/havp/tmp/* $EXCLUDE . | uuencode /dev/stdout | ssh root@192.168.0.10 "dd of=/Backup/ITWall-Test.bak" || ERROR

invocando il backup, il file viene generato correttamente ma quando tento di fare il restore (dall’apposito menu) su un’altro zeroshell, propone il seguente errore: “Error during profile restoring!!! “

Da cosa può dipendere ? in che modo posso ovviare il problema ? Nel caso non sia il “metodo” giusto, esiste una via alternativa per schedulare dei backup periodici di zeroshell senza doverli eseguire a mano ?

Saluti,
Dennis

Hello everyone,

I looked at the script in the path: / root / kerbynet.cgi / scripts /

and I saw through the console and calling up the web page was launched the following command:

/bin/sh /root/kerbynet.cgi/scripts/backupdb /udev/hda3 _DB.001 Yes

I tried to change the line 60 of script: /root/kerbynet.cgi/scripts/backupdb this:

tar cfzv - - exclude var / register / system / havp / tmp /  $ * EXCLUDE. | uuencode / dev / stdout | ssh root@192.168.0.10 "dd of =/Backup/ITWall-Test.bak" || ERROR

invoking the backup, the file is generated correctly, but when I try to do the restore (from the menu) to another zeroshell, proposes the following error: “Error During restoring profile!”

May depend on what? how can I solve this problem? If it is not “correct”, there is an alternative way to schedule backups without having to perform it by hand ?

Regards,
Dennis

Così funziona, il backup viene fatto su un mount point.. il device è USB ma funziona anche in ssh senza problemi, basta cambiare la stringa!

#!/bin/sh

BN=FWN-ITWall-CCC-`date +%a`.bak

source /etc/kerbynet.conf

function  UMOUNT () {

cd /

umount $MP/$DB.AUX 2> /dev/null

if [ "$ALREADYMOUNTED" == No ] ; then

umount "$MP" && rmdir "$MP"

fi

}

function ERROR () {

cd /

echo ERROR > "$MP/$DB/.settings/LastBackup"

UMOUNT

exit 1

}

DEV="$1"

DB="$2"

COMPRESSED="$3"

WOLOGS="$4"

[ -z "$DEV" -o -z "$DB" ] && exit 1

$SCRIPTS/umountstorage >/dev/null

NODEV=${DEV:2}

LINE=`df -T -P | grep "$NODEV "`

if [ -z "$LINE" ] ; then

MP=/storage/`echo $DEV | sed -e "s///_/g"`;

mkdir -p "$MP"

mount -o rw "$DEV" "$MP" || exit 1

if [ -r /$MP/$DB.AUX ] ; then

if ! mount -oloop $MP/$DB.AUX /$MP/$DB ; then

UMOUNT

exit 2

fi

fi

ALREADYMOUNTED=No

else

MP=`echo $LINE | cut -f7 -d' '`

mount -oremount,rw "$MP" || exit 1

ALREADYMOUNTED=Yes

if [ -r /$MP/$DB.AUX ] ; then

if ! mount -oloop $MP/$DB.AUX /$MP/$DB ; then

UMOUNT

exit 2

fi

fi

cd "$MP/$DB"

if ! [ -d .settings ]; then

UMOUNT

exit 3

if [ "$WOLOGS" = Yes ] ; then

EXCLUDE='--exclude LOG'

EXCLUDE=''

if [ "$COMPRESSED" == Yes ] ; then

rm -rf /mnt/backup/$BN

for N in `seq 1 100` ; do

echo "$N BACKUP $DEV $DB `date` ================================================================================================" >> /mnt/backup/$BN

done

tar cfzv - --exclude var/register/system/havp/tmp/* $EXCLUDE . | uuencode /dev/stdout >> /mnt/backup/$BN || ERROR

cd /mnt/backup

md5sum $BN > $BN.md5

else

tar cf - --exclude var/register/system/havp/tmp/* $EXCLUDE .  || ERROR

fi

date +"%d %b %Y %H:%M" > "$MP/$DB/.settings/LastBackup"

UMOUNT

how should one use such a script ?
replace /root/kerbynet.cgi/scripts/backupdb with this one ?
and how do i set backup destination ?

[Ihyae]

Hi (sorry for my poor English!),
this script it’s a replace of the original script.
But given that the scripts are reset to (re) boot I had to copy the script in a path which would not be reset every time you start! (eg. /Database).
As for the script I scheduled a cron once a week.
In the example I gave above, /mnt/backup is just a pendrive mounted in /mnt/backup but that is not binding.
For example, you could replace /mnt/backup with a remote destination … maybe on another server in ssh (after generating a key pair (not having to enter the pass from time to time)) by changing the script this way.

#!/bin/sh

BN=ZeroShell-`%d %b %Y %H:%M`.bak

source /etc/kerbynet.conf

function  UMOUNT () {

cd /

umount $MP/$DB.AUX 2> /dev/null

if [ "$ALREADYMOUNTED" == No ] ; then

umount "$MP" && rmdir "$MP"

fi

}

function ERROR () {

cd /

echo ERROR > "$MP/$DB/.settings/LastBackup"

UMOUNT

exit 1

}

DEV="$1"

DB="$2"

COMPRESSED="$3"

WOLOGS="$4"

[ -z "$DEV" -o -z "$DB" ] && exit 1

$SCRIPTS/umountstorage >/dev/null

NODEV=${DEV:2}

LINE=`df -T -P | grep "$NODEV "`

if [ -z "$LINE" ] ; then

MP=/storage/`echo $DEV | sed -e "s///_/g"`;

mkdir -p "$MP"

mount -o rw "$DEV" "$MP" || exit 1

if [ -r /$MP/$DB.AUX ] ; then

if ! mount -oloop $MP/$DB.AUX /$MP/$DB ; then

UMOUNT

exit 2

if ! mount -oloop $MP/$DB.AUX /$MP/$DB ; then

UMOUNT

exit 2

Another option I considered was to use samba .. up to beta 12, you can use this version: http://www.orquideadesign.com/SMB12_beta1.tar.bz2
details at this link: http://www.zeroshell.net/eng/forum/viewtopic.php?t=2209

Let me know if you need help;)
bye bye,
Dennis

thanks alot, i will try it when i finish my current project (i’m trying to make ldap clients authenticate against zeroshell, which is not that trivial 😉

Buongiorno , mi permetto di recuperare questo post di qualche mese fa sperando che a qualcuno capiti ancora di Farci un salto.
ho fatto un po’ di prove con lo script e devo dire che è tutto ok; avrei bisogno di qualche chiarimento del tipo: come e se posso automatizzare il mount della mia periferica usb ?, io ho aggiunto una banale riga allo scrittp del tipo:
mount /udev/sda1 /mnt/backup , ma mi chidevo se ci fosse qualcosa di più elegante tipo per individuare il nome della periferica automaticamente.
Spero di non aver scritto delle C

I didn’t know anybody was actively working on a massbus emulator.
