Very Long Backup Time Offline
With previous versions of TI I have always made FULL backups each time, booting to an Acronis CD. Maybe I'm just paranoid but I do this because I don't want to take a chance of any locked files being excluded. Ok, using TI 2020-Build 22510 I can backup my C and D drives (around 600GB) in less than 2 hours using the Acronis App while Windows is running. Incremental is much faster. This is to a WD Elements 8TB USB 3.0 portable HD
I created a bootable Acronis CD and also let Acronis create a small bootable partition on the backup drive . First I tried booting to the Portable HD and when I created a backup of C and D it appeared to be hung. It showed estimated backup time of 2 HRS, but still said that after about 4 hours which I then aborted. Booted to the Acronis CD. I watched the app say estimated 2 HRS for about 1-1/2 Hrs and went to bed. The FULL backup finally completed after about 7-1/2 HRS.
I believe the speed of the USB drive is fine. It is plugged into a USB3 Port using a USB3 cable, and everything else, including backups during a Windows Session seem to be lightning fast. Any ideas what is going on here? It seems the problem is only when I try to create backups while booting to acronis from another drive.

Thanks Steve. Isn't the ISO bootable media file provided (AcronisTrueImage2020_22510.iso) a Linux based compilation. I'm not all that familiar with Linux, but it appears to be Linux based.
Computer speed shouldn't be a problem, Intel I7 6700k, 16G ram, liquid cooled. and AMD R9590 video. I'm just wondering, and haven't tried it yet, but what would be the drawback of booting to one of my older Acronis 2017, 16 bootable media and creating a backup?
Since the file format would be the older and not the new .tibx would I still be able to do incremental backups using the Acronis 2020 windows app?

Yes, the .ISO is a CD image of the older Linux based rescue media.
Yes, you can still boot from your older ATI 2017 or other version bootable rescue media and create new backups in .tib format.
If you want to make incremental backups based on such .tib files, then you would need to use the 'Add existing backup' option to create a task with the same name as the file (which you can rename so long as you do this before running it), then reconfigure the backup settings.
If you are wanting to make disk backups using the old .tib file format rather than .tibx files which are now the default, then there is an unofficial way of doing this with ATI 2020 in Windows.
Take a read of forum topic: How to create a Disk backup as .tib (not .tibx) which I posted back in September which is still working for me today.
