Does anyone know if SQL Server takes into account the size of the backup file it is overwriting in the case of backing up an SSAS database?
Scenario:
SSAS Version: 10.50.2811
Existing backup: SSASDatabase.abf 65.2GB
Free Space on Drive: 99GB
XML: <Backup xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">
<Object>
<DatabaseID>SSASDatabase</DatabaseID>
</Object>
<File>\\Share\Folder\SSASDatabase.abf</File>
<AllowOverwrite>true</AllowOverwrite>
</Backup>
This fails with an insufficient space error. To make the job run successfully, I delete the existing backup and run the job from this step. The initial file size before compression now is 117GB! More than double the final result of 65.2GB.
Question 1: Is the XML correct for this? (a developer wrote this and I am not too familiar with doing these backups)
Question 2: Does it not take into account the space of the file being overwritten as free space? This seems probable, given the error. However, I would like to know if this can be verified. (I've googled, but my google foo on this is lacking)
Any help would be appreciated!
