Use XP ntbackup.exe output to Samba share for several years and never had a
problem. Backup size would range between 10 and 15 GB. Would always
perform a verify after the backup. A few months ago the process started
failing at the verify stage. The backup appeared to complete successfully,
but as soon as the verify process started a message "Error: An
inconsistency was encountered in the requested backup file." would be received.
Checked the backup file and noticed something strange. The file size
listed would be as expected 10+ GB, but the du command output stated
4KB. The process has been repeated numerous times (very difficult with a
2+ hour cycle time). I have even performed a du on the file while it is
being backed up and it grows fine, until a some arbitrary point it drops
way down, goes up and down a bit, but is always grossly under what it
should be.
I apologize for not even knowing how to get the appropriate version/release
information. Below is what I do know:
Client OS: XP SP2 (note: I think I have not had a clean backup since
applying SP2, thus this could be a source to the problem)
Server Info:
Redhat Linux
output from "uname -a"
"Linux linux 2.4.7-10 #1 Thu Sep 6 17:27:27 EDT 2001 i686 unknown"
Samba man page version heading states version 2.2 - I have not done any
reinstall so that is probably correct.
feel free to request additional information (if it involves Linux system
info, please provide instructions - much thanks).
