This page is dedicated to explaining how to automate oar backup via cron task in linux

First thing you will need to do is add the following line to your OpenSim.ini in the [Startup] section

---

       timer_Script = "backup.txt"

---

for this example we will put these scripts in the following location:

/home/user/bin

and backups will go into:

/home/user/backups

and opensim will reside in:

/home/user/opensim/bin

next you will need to create the scripts that cron task will run and the files that these scripts will copy over

---

the following files go in /home/user/bin

oarbackup_on.sh

oarbackup_off.sh

backup_on.txt

backup_off.txt

---

backup_on.txt should have the following on line 1:

---

save oar /home/user/backups/opensim.oar

---

backup_off.txt should remain blank with nothing inside

oarbackup_on.sh should have the following on line 1:

---

cp backup_on.txt /home/user/opensim/bin/backup.txt

---

oarbackup_off.sh should have the following on line 1:

---

cp backup_off.txt /home/user/opensim/bin/backup.txt

---

now to setup your cron task run "crontab -e" and add the following 2 lines:

---

0 0 * * * sh /home/user/bin/oarbackup_on.sh

5 0 * * * sh /home/user/bin/oarbackup_off.sh

---

this will run your oar backup at 12:00am every day
