I'm to backup 7GB on 9GB drive. Means, I have about 2GB of empty space only.
tar related solutions require first - get everything into 1 file, next - split it.
Is there any possibility to archive (and probably but not necessarily compress) and split, to have an ability to transfer to a remote drive chunk by chunk.
while 1st file is ready, I'm to move it to an external drive and delete from the system.
when 2nd file is ready, I'm to move ....
