Das heißt? Die starten wieder mit einem leeren Asset oder was?

[Sheera Khan]

Huhu Gubbly,

im Moment ist das OSG noch offline, aber erste Server laufen wieder an und die ersten Regionen kommen gerade an das Netz. Das ist aber eher ein Testbetrieb für die Server als für das Grid, denn offensichtlich wurde während der letzten Tage wohl auch an den Servern etwas gearbeitet: neue Hardware und aktualisierte Betriebssysteme wurden wohl installiert. Angeblich sollen 3 TB Assets wiederhergestellt sein, aber das läuft wohl immer noch. Und ob sich alle Assets dann den Eigentümern zuordnen lassen ist wohl auch noch nicht ganz sicher^^. Drücken wir die Daumen und wünschen dem OSG alles Gute.

Ciaoo

Huhus,

ein Status-Update unserer Freunde aus dem OSGrid:
http://forums.osgrid.org/viewtopic.php?f=3&t=5355&sid=00014973ef12e7aaa9a0a68fca6deb0e

TL;DR: Die Wiederherstellung der Daten beim Recovery-Service ist abgeschlossen, die Festplatte wird per Snail-Mail an das OSG-Rechenzentrum versendet, kommt irgendwann an und soll dann auf einen Testserver kopiert werden. Danach erst werden die Grid-Admins wissen, ob sie funktionierende Assets oder Bitbrei geliefert bekommen haben... Die nächsten Updates zum Thema sind dann für den 21.12. oder 22.12. in Aussicht gestellt...

Ciaoooo

Out of curiosity, does Metropolis have a strategy to prevent such disaster as has happened to OSgrid?

Also, what can I do myself to prevent such disaster from affecting my regions too much? I know my regions are in the database on my own server, but my inventory is on the grid server. What does that mean for textures I use on my regions that are in my inventory? If the metropolis grid server were to explode, I could just move my regions to another grid. But what about the textures I used from my inventory? Would I see all gray surfaces in my region after I moved it to another grid?

Hi Frost,

the Metro admins have (and the OSgrid admins have promised that from now on they will have) a real backup strategy. This means not to trust a Raid but to create separate storage. Of course, relatively small voluntary projects cannot realise continuous backup strategies, so in the worst case the latest creations may be lost. Another serious problem, which in open grids no grid admin can solve, is the import of corrupt assets, which first seem to work but have errors.

It is a good idea to create own backups of your regions, if you have built a lot of new things. If you do a full OAR backup, the assets are included. So it doesn't matter if the grid database crashes and you loose your inventory: All content which is rezzed on the region will be in the backup, including textures, scripts and whatever. Simply do not use the parameter "--noassets" if you want a full backup.

Hi Tom,

first of all, we use a different storage method with mysql and Barracuda. The method is optimized for blob storage.

Second, we store a log about all database operations. This log can be used to rebuild a database from scratch or partial.

Third, we have a triple backup concept. That means, beneath the main storage we have 2 mirrored copies of the main database.

Fourth, we store the last 10 OAR-files from our mainlands and the rented regions on different servers. For region tenents we also produce abd store IAR files. OAR for rented regions are produced automaticly and will be stored for the last 10 days.

Fifth, everyone (also without any own region) can produce and download an IAR backup with our IAR-Manager: http://manager.hypergrid.org/IAR There is also a function to import an IAR file.

But be patient: The OpenSim software is very buggy and unsafe. Your datas are not realy safe!

It could be, that the IAR or OAR could not be imported. And thats the worst, when your backups are in error and can not be used.

We suggest to install a "Sim on a Stick" as a quick OpenSim standalone version as a test-version. Then import an IAR and OAR file from time to time. Verify afterwards, that everything was imported. If so, you can lay back. You are excellent prepared for any crash and nothing can happen to you.

Hugs,
Lena

And THAT cannot be stressed enough: It is NOT enough, simply to backup your stuff *OAR for regions, IAR for inventory). You need to load the backups from time to time away from the grid to be safe that you really have all the data in a useable format and backup.

This is the step that most people forget or omit - even professional hosting companies

is better you backup a full server with TRUE IMAGE and so are you sure you have all you need database side as serverside regions and oars iars raws and all last settings
