I’m finding that some people want to come here to critique my views, attitudes, etc. And yet there is no way for me to return the favor towards them. (IE. Trolls) Those people are now banned from posting here. Have a nice day.

The “Lasivian wants an automatic Opensim backup” project.

by @ 1:45 am. Filed under Personal, Secondlife, Server Admin, Technology

It’s sloppy, but most importantly it works, and it backs up EVERYTHING. Terrain maps, world map image, .oar, .xml, all three .ini files, mysql database, etc.

I based this off the backup script here:

  • http://opensimulator.org/wiki/Backing_Up_LINUX
  • I’m running Ubuntu 11.04 server, x64 btw and this all works.

    I store both scripts in /home/username/backupdir/scripts, the shell script gets run as a cron job.

    ;Not that it *really* matter that we tell people, but I think it's polite, heh.
    screen -S opensim -p 0 -X eval 'stuff "alert Beginning full simulator backup, things might be slow for a bit.^M"'
    ;Yes, I'm redundant, this is just in case I missed something
    cd /home/username/backupdir
    ;Copy the old backups to a holding directory, I clean them out by hand every so often. This could be an offsite location.
    mv /home/username/backupdir/*.* /home/username/backupdir/old
    ;This line runs the second command script inside the opensim process.
    screen -S opensim -p 0 -X eval 'stuff "command-script /home/username/backupdir/scripts/osbackup.txt^M"'
    ;Now dump the mysql data to zip and date it.
    mysqldump -ulogin -ppassword opensim | gzip > /home/username/backupdir/opensimbackup_`date +%Y%m%d_%H%M%S`.sql.gz
    ;Copy and date the 3 .ini files
    cp /home/username/opensim/bin/OpenSim.ini /home/username/backupdir/opensim_`date +%Y%m%d_%H%M%S`.ini
    cp /home/username/opensim/bin/Regions/Regions.ini /home/username/backupdir/regions_`date +%Y%m%d_%H%M%S`.ini
    cp /home/username/opensim/bin/config-include/StandaloneCommon.ini /home/username/backupdir/standalonecommon_`date +%Y%m%d_%H%M%S`.ini
    ;The next line is just a delay so the .oar output can finish, it might take your server much longer, change as needed.
    sleep 30
    ;There is likely a much more efficient way to do the following, but this was what I could figure out
    ;these rename the opensim dumped files to add timestamps to the names. I think this makes them easier to manage later.
    for f in epsilon.*
    do mv "$f" "epsilon_$timestamp.${f#epsilon.}"
    for f in techrealms.*
    do mv "$f" "techrealms_$timestamp.${f#techrealms.}"
    for f in theta.*
    do mv "$f" "theta_$timestamp.${f#theta.}"
    for f in delta.*
    do mv "$f" "delta_$timestamp.${f#delta.}"
    for f in connections.*
    do mv "$f" "connections_$timestamp.${f#connections.}"
    ; Guessing this could also probably inform something in-world that could record backups. I'm not sure how tho
    screen -S opensim -p 0 -X eval 'stuff "alert Backup complete, thank you.^M"'

    This second script is executed inside the screen that is running opensim.

    ;Script Name = osbackup.txt
    ;executed with "command-script /home/username/backupdir/scripts/osbackup.txt" inside opensim
    change region root
    ; Persist objects to the database now
    change region techrealms
    ; export world map image
    export-map /home/username/backupdir/techrealms.jpg
    ; save terrain
    terrain save /home/username/backupdir/techrealms.r32
    ; save prims to XML
    save xml2 /home/username/backupdir/techrealms.xml
    ; save the current region to an opensim archive
    save oar /home/username/backupdir/techrealms.oar
    ; repeat as needed
    change region delta
    export-map /home/username/backupdir/delta.jpg
    terrain save /home/username/backupdir/delta.r32
    save xml2 /home/username/backupdir/delta.xml
    save oar /home/username/backupdir/delta.oar
    change region theta
    export-map /home/username/backupdir/theta.jpg
    terrain save /home/username/backupdir/theta.r32
    save xml2 /home/username/backupdir/theta.xml
    save oar /home/username/backupdir/theta.oar
    change region epsilon
    export-map /home/username/backupdir/epsilon.jpg
    terrain save /home/username/backupdir/epsilon.r32
    save xml2 /home/username/backupdir/epsilon.xml
    save oar /home/username/backupdir/epsilon.oar
    change region connections
    export-map /home/username/backupdir/connections.jpg
    terrain save /home/username/backupdir/connections.r32
    save xml2 /home/username/backupdir/connections.xml
    save oar /home/username/backupdir/connections.oar

    Use them however you want. If someone wants to clean them up for me that would be appreciated.

    Thanks & good luck.

    All the server move issues should be fixed finally.

    I added a few coded messages to the front page, some easier than others.

    Not like anyone cares, but..

    by @ 9:43 pm. Filed under Server Admin

    I moved my site to a new host and off my personal home brew FreeBSD server.

    Now i’m just fighting a bunch of little details to get it all working right.

    Ahh, fun, fun.
