Gotcha, Grafcom,
Ik heb dit backupscript zelf in gebruik (met een kleine wijziging, waarover straks meer) Mijn script ziet er als volgt uit:
#!/bin/sh
##########################################################################
# RSYNC BACKUP SCRIPT

# -s = source of rsync backup (music, photo, web, ....) - No Spaces
# -e = Ext Drive destination of backup (USB1, USB2, SATA)
# -d = Destination Directory on External Drive from top level *share/(.....) - No Spaces
# -p = Backup Partition Type is EXT3
# -u = Update mode
# -l = log file
# -q = quiet
# -v = verbose
# -n = No Execute Rsync just check validity of other switches

Wat heb ik hiermee gedaan?
Ik heb deze code opgeslagen in een bestand BackupSyno.sh op /volume1 (plaats is niet zo heel erg van belang...). Wel van belang is dat je er voor zorgt dat er geen ^M's aan het einde van de regel staan. Als je de tekst bv. via kladblok bewaart en vervolgens naar je Syno kopiëert heb je hier last van... Je dient de tekst op te slaan in Unix formaat.
Vervolgens log ik via telnet/putty in op de Syno en geef het volgende commando:
sh padnaarbestand/BackupSyno.sh -s volume1 -d . -e USB1 -l backup.log -v -uWat gebeurt er dan?
BackupSyno wordt gestart met als parameters:
-s volume1 (bron van de backup is /volume1)
-d . (doel van de backup is de root van het backupmedium)
-e USB1 (doelschijf is de disk op USB1)
-l backup.log (zo gaat de logfile heten)
-v (laat zien wat er gebeurt)
-u (sla reeds bestaande bestanden in de doeldir over)
Ik schreef al dat ik wat gewijzigd had. Dat betreft het stuk code van regel 161 t/m 164 (
BACKUP_SOURCE_PREFIX="/volume1/"
#TO BACKUP BEYOND /VOLUME1/SUBDIR (E.G./VOLUME1 AS ROOT) USE: BACKUP_SOURCE_PREFIX="/"
#TO BACKUP FROM ROOT (/) USE:BACKUP_SOURCE_PREFIX=""
#BACKUP_SOURCE_DIR=$BACKUP_SOURCE_PREFIX$PASSED_SOURCE_DIR)
In het script zoals dat in de Wiki staat is de BACKUP_SOURCE_PREFIX="/volume1/"...
Aangezien ik geheel volume1 wil backuppen en niet slechts een subdir van volume1 heb ik hier BACKUP_SOURCE_PREFIX="/" staan.
Als je de hele Syno wilt backuppen laat je de prefix leeg en geef je als -s op '/' (zonder de quotes...)
Wellicht behoeft de doeldir ook nog enige verduidelijking (-d .) Als je het script doorneemt zie je dat de backup weggeschreven wordt onder bv. USB1/usbshare. Door nu . als doeldir op te geven wordt mijn hele volume1 onder usbshare weggeschreven.
De log is te vinden in USB1/usbshare als backup.log
Het prettige aan deze manier van backuppen is dat na de eerste keer backuppen enkel de verschillen worden weggeschreven (optie -u). Backuppen duurt eindeloos lang de eerste keer (het gaat niet zo hard naar die usb-schijf), maar een volgende backup overschrijft enkel de toegevoegde/gewijzigde bestanden (en verwijdert de niet meer bestaande).
Succes!
