SYMPTOMS
When you try to perform a backup, restore, or compare operation in Microsoft Backup, or close Backup after performing one of these operations, you may receive the following error message:

Microsoft Backup has encountered a serious error in the Memory Manager.

Quit and restart Backup, and then try again.

CAUSE
This error can occur for any of the following reasons:


 * An incompatible device driver or memory-resident program is being loaded in the Autoexec.bat, Config.sys, System.ini, or Win.ini file.
 * The Windows swap file is damaged.
 * The tape drive or backup tape you are trying to use is damaged or incompatible with Backup.
 * One or more Backup files may be damaged.
 * The memory in your computer is faulty.

NOTE: If the above error message is displayed when you attempt to perform a restore operation in Microsoft Backup, the problem may also be caused by the method Backup uses to read restore information in some situations dealing with compression.
