The CA Data Protection (DataMinder) Event Import functionality enables users to integrate with third-party email archives and file storage locations.  It can be configured to import email files in .eml format from these sources.



Why does CA Data Protection (DataMinder) fail to import .eml files of approximately two gigabytes or over?



The CA Data Protection (DataMinder) import service has been developed around the x86 32-bit architecture.  32-bit applications have a limitation where they are unable to allocate more than 2GB of memory.  Because of this limitation, the import process will fail on a file of this size.



Please note that, the limitation refers to importing a single file of approximately 2GB in size (or larger) and not on importing a larger file or folder that contains multiple emails that total over 2GB.

The 2GB file size limitation discussed in this technical document is an approximation as there will be a system overhead associated with the import process itself.  Therefore you might notice this issue with files close to but not exceeding the 2GB limit.
