Some ideas to consider:
I have not used Acronis products in several years now so I'm not up to speed on all the capabilities so you will need to verify that the things I say here are applicable to Acronis Cyber Protect as well, but my suggestions here are based upon the capabilities of Macrium Reflect.
Idea #1: Many disk imaging programs (Macrium Reflect included) can do both a disk image backup and file / folder backups. In addition, Reflect X can exclude files and folders from an image backup. As a result, you may be able to perform backups to small external drives. Here is how I do this:
In this example, I have a 1TB NVMe drive in my laptop, and I have two 512GB UFDs (USB Flash Drives). I backup my NVMe drive to one of those UFDs but I exclude my data folders where I keep all my personal data, music, copies of software, Windows disk images, etc. This way my disk image backup can easily fit onto one of those UFDs. Then, I perform a second backup, this time a file and folder backup of my data folder(s) to the other UFD. In both cases I end up with lots of room to spare on the UFDs so I can follow up my original full backups with incremental backups at a later time that will be performed far faster than the original full backups.
Idea #2: If your software cannot exclude files / folders from the disk image backup, consider making a separate data partition on your drive. As an example, you would have your Windows partition (C:), but also a D: partition where you keep all your data. Now you can create one disk image backup that omits the D: partition and another image that omits C: as well as the MSR, Recovery, and EFI partitions.
The idea behind both plans is to make each backup smaller so that you can use smaller external drives. I like to use the "PNY PRO Elite V2 USB 3.2 Gen 2" drives because they are every bit as fast as SATA SSDs and they are tiny - even smaller than many other UFDs. This allows me to carry it in my laptop bag while consuming only a trivial amount of space. That way I always have my backups with me.
NOTE: Best practice would dictate that you create at least one additional backup that you keep in a separate location.
I hope that this at least gives you some ideas on potential strategies. If you have any questions at all, please feel free to ask.
