Why do brick level backups at all? There are products available that can take a BKF file and pull one mailbox out to a PST file and you restore from that.

Smith Sent: Thursday, June 29, 2017 8:35 AM To: exchange@lists.myitforum.com Subject: RE: [Exchange] June 2017 Quarterly Exchange Updates Backup Exec (and every backup program promising single-item restores) depend on non-public data – they are reverse-engineering the format of a mailbox database.. This is noted in the release blog. Post release update concerning Cumulative Update 5 Several customers have reported problems with 3rd party solutions which provide brick level backup or single mailbox recovery as a reported feature after installing Cumulative Update 5. Cumulative Update 5 included an update to our database schema which caused some of these products to not function as they had previously. That change carries forward into Cumulative Update 6 as well. The practice of updating the database schema has long been in place with Exchange Server. Microsoft has urged developers to not consider the schema to be immutable nor to program against it. The schema is not publicly defined and is a structure internal to the operation of Exchange Server. Access to store level objects is provided through publicly documented interfaces and structures only.

However, if you do a lot mailbox moves or discovery searches, I suggest that you carefully test it in a lab. The same if you intend to apply CU6 to edge servers. I am not aware of confirmed issues, but I’ve heard some rumbles about these.
