Get Info on the destination drive reports 8.91 GB available.

I am happy to format the destination and start again (I keep a
SuperDuper backup off site).
But... what is the problem?

Hello Dennis,
You don't mention what size your internal harddrive is & what size the
external drive you are backing up to is?
The internal drive is 300GB and the destination is 500GB but that is
really not an issue. TimeMachine has been working since January without
problems and is working still.
I got that one error message that had the required size of 1GB but an
available size four times that size. And the Finder reported twice as
much again.
For each backup that TM performs, it adds about 20% for workspace.
I don't understand this. 20% of what?
The recommended size of a TM drive is at least 2x to 3x the size of
the internal drive.
Cheers,
Ronni
I just had a thought (dosen't happen often)
If the destination is full and TimeMachine delets the oldest backup then
there is a potential increase in available space on the destination so
that might explain the larger Finder report but the initial TimeMachine
error still seemed to want less than what it said was there. Why would
that be a problem?
This is for interest only as all seems to be working fine now.
Dennis.
