i used to use a DDS3 tape drive on the back of my then daily driver A4kT with a licensed copy of diavolo backup.
then i sold the A4kT when i went PC; thinking i could just keep the tapes and restore back to an amiga when i got a machine capable enough again.
then i lost the tapes and a few big boxes of disks in a house move.

everything gone. years of creating stuff just tipped in the bin somewhere. Thanks big yellow storage.
so i don't really care now. i just use pre-built WB distros - they're usually much better than anything i could have the time to put together. and slap on the relevant P96/USB/network device drivers/stacks to the machine i'm setting it up on. if i get a half decent stable system then i'll copy it over SMBFS to a share on some NAS. or if the case is off and the amiga in question is running on a CF card, i'll pull the CF card, plop it in a USB3 media card reader and make an image of it on a PC and dump that to NAS.
if you dump the amiga disk to NAS keeping the file structure raw, instead of lha'ing everything up - it's only a matter of a few clicks in winUAE to boot from that folder if you need to do something a bit quicker than on original hardware.
