Connect with SSH to your Synology NAS:

ssh root@<ip-address>
root@<ip-address>'s password:
<password> 

Run all the following commands on your command line:

Important: Replace these sample data with your own data!

Your online backup acount (z.B. 4000000):

OnlineBackupUser=4000000

The place, which you noticed out of the web interface in the last step (default is "/volume1/OnlineBackup"):

OnlineBackupDir=/volume1/OnlineBackup

Schedule the hour for the automatic backup (cronjob):

OnlineBackupHour=01

Schedule the minute for the automatic backup (cronjob):

OnlineBackupMin=00

Copy the following code into your command line and execute it:

# change into previously created online backup directory
cd $OnlineBackupDir
# decompress the previously downloaded file
unzip latest.zip
# clearing up
mv online-backup-latest/* . && rm latest.zip online-backup-latest/ -R
# generate a ssh key
ssh-keygen -t dsa -b 1024 -N '' -f conf/onlinebackup_id_dsa
# readout the backup name
OnlineBackupName="$(/bin/hostname)"
# copy the configuration files
cp conf/OnlineBackup.conf.default conf/OnlineBackup.conf
cp conf/OnlineBackupExcludeFiles.conf.default conf/OnlineBackupExcludeFiles.conf
# adjust confiugration
sed -e "s/^REMOTEUSER=.*/REMOTEUSER=${OnlineBackupUser}/" \
 -e "s/^REMOTEHOST=.*/REMOTEHOST=31.216.40.129/" \

 -e "s/^SCHEDULEDHOUR=.*/SCHEDULEDHOUR=${OnlineBackupHour}/" \
 -e "s/^SCHEDULEDMINUTE=.*/SCHEDULEDMINUTE=${OnlineBackupMin}/" \
 -i conf/OnlineBackup.conf

Determine the backup scope:

Set the absolute path of the folder, which you desire to include in your backup (e.g. "/volume1" for the whole volume). Subfolder are included automatically.
If you desire to include serveral folders, run the following commands repeatedly:

OnlineBackupInc=/volume1

echo ${OnlineBackupInc} >> conf/OnlineBackupIncludeFiles.conf

Copy the public ssh key onto the backup server:

rsync conf/onlinebackup_id_dsa.pub ${OnlineBackupUser}@31.216.40.129:.ssh/authorized_keys 

Testing the connection:

ssh ${OnlineBackupUser}@31.216.40.129 -i conf/onlinebackup_id_dsa 

If you could connect successfully, press CTRL-D to exit.

Testing and initialize the online backups:

This process might take several minutes!

${OnlineBackupDir}/bin/OnlineBackup.pl -c ${OnlineBackupDir}/conf/OnlineBackup.conf
