SharePoint 2007 Content Databases becoming more than 100GB

I have 20 Site Collections and 1 Content Database which is becoming more than 100GB.

What is the best approach to handle this i.e. Content DB split? Do i need to change my architecture? Need to consider MOSS2010 upgrade in 2011 as well.

 I need recommendations of steps architecturally to ensure:

- least impact to the business users
- no URL change if possible
- scalability so we wont have to split again in future

Please do not paste links that you are unsure and does not give me the above solution points.

Check this article out on moving the data:

I posted this solution a while back and it works very well.
Simply set the current content database to offline (this means no new sites will be created in it) and add a new one. All new sites will be added to the new content db. Do this all in Content Databases within application management in central admin, make sure to select the correct web app.

You can, if you want, use stsadm to transfer existing site collections from one content db to another without impacting urls.

Do this before getting to 100Gb in future. When creating your content db set the max number of sites and the warining level. Use quotas to manage the size of sites and you should be able to pre-emt any problems with db size.

I hope this helps

Won't the new sites created in the site collection be on a different URL?

No, just the content will be in a different database.

You can add multiple content databases to the same web application and hence not change the url of the web application.


Just one comment - setting the database to offline and adding a new database will ensure that the new site collections will be created in this new db. However, a sub-site created in an existing site collection, will go into the initial database. A site collection cannot be split into multiple databases.

I agree with FFNetAdmins - you can move some of the site collections using stsamd -o backup/restore rather easy.

Hmm. 8 of my site collections are 80GB each. It will grow into 100GB soon.

I need to split my site collection but can i do it without changing url?

If you want to split a single site collection in multiple site collections, you can use stsadm -o export/import.
And you can keep the same URL, if you create managed paths.

However, keep in mind that export/import has some limitations:
-can only do it for an entire branch (a site and all it's sub-sites)
-it needs about twice the amount of space used by the site to expand while exporting/importing
-it will use the space on default drive (C), so you may watch that one closely
-workflows/alerts will not be included in the backup, so you will need to recreate them.

hope this helps

Can you please explain how i can keep the same URL?
Let's say your subsite is named http://root/sites/site1/site2
You can backup site2 (stsadm -o export), rename site2 let's say to site2old, create an explicit managed path "sites/site1/site2", create a new site collection at this new managed path (i'm using blank template, to avoid issues at restore caused by the default libraries/lists that get created), then restore backup over this new site (stsadm -o import).

There is a recommended limit to the number of managed paths per web application (sorry, don't remember the exact link or number), so it is good to do an analysis before breaking the site collection, so that you don't split the site collection into too many pieces.
