like i would just tar the / filesystem, but there's not enough space on disk to have a tarball of everything else

@freyalikesgirls @green Tar does make sense, -czf creates a gzip

@star @green @freyalikesgirls yes, by invoking gzip and adding an unused header. tar is for packing many files into one, the other tools for compressing the file. tar czf foo.tar.gz bar does the same as tar c bar | gzip > foo.tar.gz

@star @freyalikesgirls that's gonna be a very annoying backup to later recover. i would have to somehow turn the file into a block device and then mount it

@freyalikesgirls @star i think it would be easier to just do a normal tar, and pipe the output over stdout. or the normal way of rsyncing the whole filesystem and tar.gz-ing it locally

@green @freyalikesgirls But if you don't want to compress it right away, don't use TAR, just pipe the raw bytes of the disk image into a .img file

@green @freyalikesgirls That's the absolute closest you can get to a 1:1 copy anyway, since that is literally what it is

@green @star @freyalikesgirls you can use losetup to expose that file as a block device (on /dev/loopX) and then mount that or do whatever you need to do

sudo losetup -f MYFILE and it'll give you a loop device to do your stuff with
