Posts Tagged ‘remote blob storage’

Dear all,

 

Shallow Copy is one of the new features added by the SharePoint Server 2010 SP1. Citing Microsoft, it does the following:

 

Shallow copy is a migration technique in which structured site collection data is moved across content databases while the unstructured data remains untouched in its originally configured BLOB store.

 

Sounds good, doesn’t it? In other words: The effort to migrate RBS-enabled site collections is greatly reduced – because we don’t have to consider the moving of the BLOB content anymore. Good!

 

The shallow copy can be performed using the Move-SPSite cmdlet, by simply specifying the RbsProviderMapping parameter. Here is an example:

 

Move-SPSite -Identity <Url> -DestinationDatabase <DB> 
–RbsProviderMapping @{"sourceProvider1"="targetProvider1",
"sourceProvider2"="targetProvider2"}

 

As stated before, only the structured content database is copied, while the unstructured content, such as BLOB files lying on file systems, remains untouched. Only the ownership information for the BLOB content is copied to the destination database.

 

Stay tuned till the next time!

Best regards,

Martin
