Newbie - Complete verification of backup

[banger696]

Just ran my first backup to an external USB HDD. I have a mix of Windows and Linux systems so have done a partition backup. When verifying the backup the quick verification takes seconds but the complete takes several hours. I did a differential after the main backup, does the complete verify check the initial backup and differential that might account for the time to verify.

Also does Hasleo Backup Suite support Ext4 partitions or is it best to do a sector by sector backup.

Thanks
