Differential backups saved on multiple external hard drives
I save my weekly differential backups to external hard drives. I have the initial full backup on Hard Drive A but the differential backup that I want to restore from is on Hard Drive B. Will TIH be able to use both external hard drives to accomplish the restore, or do the initial full backup and the differential backup need to be saved together on the same hard drive?

Correct.

No, they're on different external HDDs. That's exactly my question.

Eliezer, sorry but your approach above is storing up serious issues for you as ATI has never been capable of working with multiple drives, and especially not with storing files belonging to the same backup task / chain on different drives.
You need to modify your approach here;
Create one backup task for each different backup drive, then run each task as required but keeping all the files on the same drive for each task.
Your current approach will not be recoverable from the Acronis rescue media.

Thanks, Steve.
What I've been doing is having TIH save my differential backups weekly to an secondary internal hard drive. Then monthly, I manually copy those backups to an external hard drive. When the first external hard drive ran out of space, I continued copying the subsequent ones to another external hard drive. But the result is that I've got the first bunch of weeks' backups on one external hard drive - and the more recent bunch on another external hard drive.
I'll change my approach to keep the entire backup for one job on one hard drive. The problem is that once that external hard drive fills up, I basically need to start a new series. I don't like that... I guess that's just a TIH limitation.

With ATI 2020 it is even more important to keep all the files for any backup task together, as these are all directly related internally.
See the following KB documents published by Acronis with regards to .tibx files.

Steve, regarding what you wrote:

Is my manually copying the files from my internal drive to an external one (as described in my last post) going to make any kind of issues when trying to restore?

It shouldn't cause any issues provided that you copy all of the files from the internal drive to the external drive, with awareness that ATI 2020 changes the first .tibx file to hold metadata for the whole backup chain each time a backup is run, where that first .tibx file becomes only 12KB size.
Take a browse through forum topic: Full Backups no independent entity - where another user was hitting problems when moving backup files.
