I think I still have an ISA bus Backer card in a box somewhere.

I got it second-hand for not much money and was pleased to have it. At the time, it was the only practical way for me to back up my 500MB harddrive.

My vague recollection is that the software that was supplied with it, for windows 3.11, could store about 500MB on a three hour VHS tape.

I tried various settings in the software and reading a tape holding files of mostly under 1MB in size always gave a checksum error on two or three files.

A different VCR might have worked better.

I would let a backup run for three hours, wait another three hours to play back the tape then copy the few files that could not be read to a floppy disk and keep it with the video cassette.
