- DSpace AIP Format (METS-based) (default) - This is the same AIP format utilized by the DSpace AIP Backup and Restore feature, so it is 100% compatible with that DSpace feature. In fact when using this format, the Replication Task Suite just "wraps" calls to the AIP Backup and Restore feature itself.
- BagIt AIP Format - This is a new AIP format provided by the Replication Task Suite. It generates AIPs in the BagIt File Packaging Format. Institutions which already are familiar with BagIt or use it elsewhere may find this format preferrable.preferable. (Please note that this AIP format does not yet support all DSpace objects. See the below table for more information.)
These two AIP formats are not identical. The below table seeks to describe some of the differences.

| Can Backup & Restore Item Versions (added in DSpace 3.x) | No (Item Versioning not yet compatible with AIP format) | No (Item Versioning not yet compatible with AIP format) |
