A large portion of the space required by Retrospect is temporary data that is erased after an execution occurs.
The calculation above takes into account the following:
When backing up large numbers of files, Retrospect will use 40-45% of RAM and then cache to the page file on the System Volume’s temp directory (usually C:\Windows\Temp) thereby increasing disk usage.
When grooming snapshots, Retrospect will use the Config folder (C:\ProgramData\Retrospect) as a work space in determining older files that need to be removed from the backup set.?
The Retrospect Config files "configxx.dat and configxx.bak" (C:\ProgramData\Retrospect) can grow extremely large depending on how many scripts, clients, backup sets, selectors, etc. you have.
By default, the backup set catalog files are stored in the "My Documents" folder.?Catalog files can grow extremely large if you are backing up a large number of files ex. Millions of files. If Catalog Compression has been enabled, Retrospect will de-compress the catalog file in the same folder during an execution thereby increasing the size of the catalog file.
