Backup File Size is different to what is displayed in the enumsites!

September 10th, 2009 Dominick Cosgrove No comments

While assisting a client in moving content from one environment to another for testing purposes, it was noticed that the site of the stsadm backup file was considerably larger than the Content Database size as defined in the stsadm enumsites report.

As can be seen in the from the out put of the enumsites, the StorageUsedMB for the HRTemp site collection is reported to be 158.4 MB. However the size of the backup file is 3.1 GB.


<Sites Count="5">  <Site Url=http://portal Owner="domain\spadmin" ContentDatabase="WSS_Content"StorageUsedMB="1.7" StorageWarningMB="0" StorageMaxMB="0" />  <Site Url="http://portal/teamsite/hr" Owner="domain\spadmin"  ContentDatabase="WSS_Content_HR2" StorageUsedMB="3171.1" StorageWarningMB="0" StorageMaxMB="0" />  <Site Url="http://portal/teamsite/HRTemp" Owner="domain\spadmin"  ContentDatabase="WSS_Content_Temp" StorageUsedMB="158.4" StorageWarningMB="0" StorageMaxMB="0" />  <Site Url="http://portal/teamsite/it" Owner="domain\spadmin" ContentDatabase="WSS_Content_IT" StorageUsedMB="8840.7" StorageWarningMB="0" StorageMaxMB="0" />  <Site Url="http://portal/teamsite/research" Owner="domain\spadmin" ContentDatabase="WSS_Content_Research" StorageUsedMB="14.5" StorageWarningMB="0" StorageMaxMB="0" /></Sites>
 
I asked if they had deleted any files and if so had they deleted the files from the recycle bin. They said that they had deleted files and removed them from the recycle bin. As it transpires they had removed the files from the users recycle bin and not the site collection recycle bin.

Once the files were removed from the site collection recycle bin the backup file was reduced to the expected size.

It is therefore important to ensure that files are deleted and removed from the recycle bin properly before executing a stsadm backup as files in the recycle bin for the site collection will also be backed up and this will not be reflected in the enumsites report.

Note: You can disable the recycle bin thus purging the recycle bin using the setproperty method of the stsadm command. Beware that this property is for the Web Application and not the site collection, and will as a result empty (delete) the recycle bins for all site collections in the web application. This is OK for testing purposes, but not recommended in production environments.
