My time machine has decided it doesn't want to backup anymore, i have a 1TB external hard drive everything was working fine then it "failed to backup not enough space" but there is 144GB left, also i can't go back to any files beyond the last backup, i have run first aid and no problems, ejected and restarted still won't backup, this is about as far as i'm confident of going, is it worth reformatting and starting again. Read so many solutions but they seem beyond me just need simple help.

I've had this problem before, and have solved it by temporarily excluding large directories from Time Machine. It seems to trick Time Machine into thinking it doesn't need as much space to back up as it wants. Then when it completes succesfully, remove the exclusion and all seems well again.

OP:

Try a cloning app for backing up -- either CarbonCopyCloner or SuperDuper.
Both are free to download and use for 30 days.
Very easy to get running, up-and-running in seconds.
CCC can even clone the recovery partition.

You can boot from the backup, mount it right on the desktop, copy one file, several files, folders -- or the entire drive.

I suggest you try it.
If you don't like it, just erase the drive and move on...
