We have had alot of trouble with a particular clients backup. For a year their backup was running without problems until recently...
2 External harddrives were being used to backup the server, being swapped about. These are connected via USB.
The backups started to fail and stop detecting drives intermitently so we done the following:
* Swapped to a new HD Drive
*Swapped to a new HD external enclosure.
*Swapped USB ports and even added a separate PCI USB adapter.
This worked for 1 or 2 backups then started to fail again. With a NTFS write error.
"New Technology File System (Ntfs) - Delayed Write Failed - Data loss occur"
After abit of research it seems that the error is related to some kind of Data or memory leak.
Hardware tests on both Memory and Harddrive came back good so we have narrowed it down to a NTbackup problem or windows problem.
Any Help is much appreciated
