30	30	== Database Attachment Store (Default) ==
31	31	This attachment storage mechanism stores your attachments in database entries in the [[xwikiattachment_content>>platform:DevGuide.DsXWikiAttachmentContent]], [[xwikiattachment_archive>>platform:DevGuide.XWikiAttachmentArchive]], and [[xwikiattrecyclebin>>platform:DevGuide.DsXwikiRecycleBin]] tables. This system allows for easy backup of your attachments by dumping the database and keeps all of your data together but attachment size is memory constrained since the attachment content and archive must all be held in memory. As a general rule, attachments larger than 30MB are not possible.
	34	+**Note:** When using this attachment store with a MySQL database, you must set the ##max_allowed_packet## to about 3 times the size of your largest attachment since the attachment and it's version history must be saved. See [[platform:AdminGuide.InstallationMySQL]] for more information.
