A Veritas Enterprise Vault 12.x environment contains a Vault Store Group called VSG1. VSG1 contains two Vault Stored, JournalVS and MailboxVS, each of which has its sharing level set to "Share within group". Bob sends an e-mail to Alice at 12:00 PM, a copy of which is sent to the journal mailbox and archived shortly thereafter by the Journal Archiving task to an Exchange Journal Archive residing in JournalVS. Later that night, during the scheduled mailbox archiving window, Alice's copy of the e-mail is archived from her mailbox to her archive which resides in MailboxVS.
Which files will be created in the open Partition of the MailboxVS as this e-mail is archived from Alice's mailbox, based on the Optimized Single Instance Storage (OSIS) model?
