Hello everyone!
How much space is necessary for the destination drive when creating a backup? And does the destination drive need to be empty or can it have other files in it?
Thanks!

For a backup image, the destination drive can contain other files, though due to Rescuezilla v2.4.2's still imperfect handling of special characters it's recommended to have your backup image folder near the top of the destination drive rather than deep down a folder hierarchy.
The exact amount of free space required varies.
If you have a 50GB of used space on a 1000GB drive, for example a fresh install of Windows, then your backup image will typically require about 50GB. Custom compression settings (such as zstandard compression with a higher compression level) can bring this down further, but often at the expense of taking longer to create the image.
If the above 1000GB drive was encrypted, Rescuezilla 2.4.2 would likely have to copy the full 1000GB onto the destination drive.
Note: for encrypted partitions or partitions containing already compressed data like modern video files, any kind of compression typically has no effect on the file size (possibly even increasing file size) because compression works by identifying repeated segments, and encryption or video compression makes large amounts of repeated segments extremely unlikely.
