NTFS Compression Limit

Windows 2003 Server R2 Weridly I’ve not spotted this on the net anywhere but I think there’s a fault with the NTFS compression or something.
For the last few weeks I’ve had Windows Backup writing a backup file to a 500Gb USB HD connected to the same server. It’s been backing up the server into 50Gb – 70Gb files without a problem until I compressed the DIR that it writes to. Then it’s been moaning that the disks where corrupt and loads of other daft errors. Game up trying to get to the bottom of it but after turning off the compression again everything is back to working again !

So it seems that there’s something funny when compressing a 50Gb file or more live onto HD drive. Not sure if it’s just over USB but it’s working now. Interesting though

? NTFS 50Gb Compression Limit ?
