With a very large pst-file, it will take a long time to scan. Its given that the larger the pst-file and the more items it contains, the longer it will take for it to complete. Scanpst.exe is a very disk intensive operation as it will check every single bit of your pst-file for integrity issues and also cross-references several indexes. In case of any errors, you might be using scanpst.exe to check your pst-file for errors, then size is a big issue. Together with the 7 daily backups of your “active” 1GB pst-file this would only take up 9GB + 7GB = 16GB of space. When you have 3x3GB “archive” pst-files which no longer change, you don’t have to back them up on a daily basis anymore so they will only take up 9GB. When you have a 10GB pst-file, this would take 70GB. The 3x3GB ones only need to be backed up once and the 1GB one regularly which is quicker than regularly backing up the entire 10GB one.īuilding on the previous example, assume that you want to create daily backups of your pst-file and keep a history of 1 week.

Having 3 “closed” archives of 3GB and 1 “active” archive or mailbox of 1GB is easier and quicker to backup than having one large “active” archive of 10GB. With pst-files, it is of course important to back them up. You can increase the pst file size based on three factors: Recommended size is 2GB, you should avoid further pushing it. You can re-enable caching if your hardware allows.
