Hi
I've used Hyper Backup to backup my entire NAS (DS 218J) to a USB drive using the Local (single version option) and it copied the full 2.5TB of data to the USB drive. However when I use the Local (multi-version option) with encryption I get a backup size of just 1.4TB - what's going on?
I know I have duplicate files on the NAS but I'd be surprised if it was 1.1TB worth of data. I'm not running compression on the backup either so am concerned some files are not getting backed up. Any way I can check what is happening, and does this seam normal? Could it be duplicates, if so how can I check to be sure? Why did the other backup option result in a 2.5TB backup and this one only 1.4TB? Sorry I'm really confused.
My plan was to take the multi-version encrypted USB drive off-site (leaving it in my work locker) as an off-site backup - hence wanting to keep it encrypted, bringing it back from time to time to update the backup. So I want to ensure this is really a full backup of my drive.
Thanks
