When files you expect to have backed up do not appear in the Restore window, check the purge settings on the RBS Endpoint to make sure they are correct. The most common cause for files missing from the restore window is that the purge settings have been set too short, and backup files are being retired sooner than you would like.

Go to Options : Preferences and then double click the padlock icon and enter the password (The default is "Admin" with a capital "A", but this can be changed in the Customize Endpoint Installer tool.

Click OK on Preferences window.

Now go to the Schedule : Backup Schedule window. Check the purge settings to make sure they are correct.

You can also check the backup log sent by this Endpoint. It is in this Endpoint's root directory on the RBS Server.

Search the logs.zip folder in this Endpoint's root directory. Arrange them in modified date/time format. Check few of the recent backup logs and confirm if these files were backed up correctly.

If you have set the purge/retention settings incorrectly and files really are missing there is nothing you can do inside RBackup to recover them. However, you may still be able to recover them from the Recycle Bin, or you may be able to use one of the many "Unerase" utilities to un-delete them from the Server.
