SYMPTOMS
When you use a batch file to back up directories, you will receive the following error message:

Backup: NTBACKUP.EXE - Application Error The instruction at "XxXXXXXXXX" referenced memory at "XxXXXXXXXX". The memory could not be "read".

Click on OK to terminate the application Click on CANCEL to debug the application



CAUSE
The above error message occurs when a line in a batch file (that calls NTBACKUP) contains a directory list that exceeds 282 characters.

For example, the file BACK.BAT contains the following lines: ntbackup backup d:\one\ d:\two\ d:\three\ d:\four\ d:\five\ d:\six\ d:\seven\ d:\eight\eight\ d:\nine\nine\nine d:\ten\ d:\eleven\ d:\twelve\ d:\thirteen\ d:\fourteen\ d:\sixteen\ d:\seventeen\ d:\eighteen\ d:\nineteen\ d:\twenty d:\twentyone\ d:\twentytwo\ d:\twentythree\ d:\twentyfour\ d:\twentyfive\ d:\twentysix\ d:\twentyseven\ This file has more than 282 characters on the backup line and will causes the error message.



RESOLUTION
There are three possible workarounds to this problem:


 * Decrease the number of characters in the line to 282 characters or less.

-or-
 * Use the Backup application from the Administrative Tools group to initiate the backup.

-or-
 * Split the line up into 2 lines or more.

For example, the file BACK.BAT contains the following lines: ntbackup backup d:\one\ d:\two\ d:\three\ d:\four\ d:\five\ d:\six\ d:\seven\ d:\eight\eight\ d:\nine\nine\nine d:\ten\ d:\eleven\ d:\twelve\ d:\thirteen\ d:\fourteen\ d:\sixteen\ d:\seventeen\ d:\eighteen\ d:\nineteen\ d:\twenty d:\twentyone\ d:\twentytwo\ d:\twentythree\ d:\twentyfour\ d:\twentyfiveseven\

ntbackup backup d:\one\ d:\two\ d:\three\ d:\four\ d:\five\ d:\six\ d:\seven\ d:\eight\eight\ d:\nine\nine\nine d:\ten\ d:\eleven\ d:\twelve\ d:\thirteen\ d:\fourteen\ d:\sixteen\
