i tend not to back up because atleast for me thats how unfinished things start to pile up
i work on them until i am happy, record them over to ableton, wipe the tape and keep it moving
for me this is the best way i’ve found to stay productive and not get stagnant
but i do understand that everyone is different and has a different way of working
and has different intent // goals in mind
over the years i found that once i had moved on
i never went back to revisit things i thought i needed to preciously archive anyway
i’ve lost everything many times. entire hard drives of things.
while the first time i almost had a panic attack it helped me let go
and understand that all things are mostly temporary
build and destroy and rebuild again its no biggie anymore.
make something new. make something better. keep learning. keep evolving.
this is maybe not the type of answer u were looking for but just my 2c
