Hi

I posted this on apple discussions , but not really resolved, any one else got this problem

I have two computers running 10.6.2, both backing up to a Western Digital World Book 1TB, running the latest firmware, using Time Machine.
This device supports Time Machine according to WD's web page.

One computer, within 24 hours of the initial backup, starts to backup large amounts of files, approx. 80Gb.
There is no way that I have made these amounts of changes, all prior backups are what I regard as typical for the work I do, max 300Mb.

Excludes on this machine appear to be ignored.

The other computer backs up correctly.

Also, using an USB disk on the machine that makes big backups, the problem is not there, so its one machine using the network drive, that has this problem.

Any thoughts?

Did you relocate any large files on the computer?

No large file movements, just day to day work.

Currently I have set up a sparse file on the server for the computer giving me the problem, and I am now backing up to the network file server using that method, while the other machine is still using the time machine account.

If this works I suspect its a problem with the software in the network server, ie unable to cater for more than one client using its time machine emulation.

If it does not, back to Plan B, using an attached USB drive.

PS when it started to go wrong, it wanted to backup the entire system and attached disks, over 150G!!.

Currently using the new sparse file plan, it has just backed up 5G, thats normal as I backup mail etc daily, and also I downloaded some raw files from my camera.
