Microsoft Backup and Microsoft Backup for Windows may fail and generate
"insufficient disk space" error messages when you are backing up to a
network drive, even if the drive has plenty of room. This problem occurs if
the network connection times out when Microsoft Backup is trying to
increase the size of the backup file.
CAUSE
When Microsoft Backup allocates space for a backup file, it fills the
file with zeros. If the file increases by several megabytes, it may
take several minutes to "zero out" the new space. If the network
redirector determines that the network is not responding (because this
process is taking so long), the redirector may cancel the network
connection.
RESOLUTION
To work around this problem, increase your network timeout setting to
several minutes. For example, if you are using Windows for Workgroups,
increase the SESSTIMEOUT=nnn entry in the [network] section of the
SYSTEM.INI file.
