Error Message

Backup completion % is reported negative, 0 % or inaccurately.

The formula used for backup completion percentage in DLO 9.4 and earlier is - 
Backup Completion % = ( (FileSizeOriginal - FileSizeToProtect) / FileSizeOriginal ) * 100
Issue is seen when size of data pending for backup is more than the already backed up data in source.

This issue is resolved in DLO version 9.5. DLO 9.5 download link.

Starting DLO version 9.5 backup completion percentage formula is updated to following which resolves the errors in backup completion percentage value calculation:
Backup Completion % = ( FileSizeProtected / (FileSizeProtected + FileSizeToProtect) ) * 100

To track 100 % backup completion for client refer to Time of Last Successful Backup column.

Time of Last Successful Backup – This column displays the last time when the Desktop Agent backed up user’s data completely. In simpler terms, this is the time stamp when the machine had achieved a 100% Backed up status (all files in the Backup selection backed up). In case of this column being blank for a computer, it could be interpreted as the first backup, as the computer has not been backed up completely even once.

Also review: DLO Backup Completion % is displayed as 0%, incorrect, unknown, blank or not 100 %
