We have set up HSM to store older messages on different network storage outside VM. We did similar with zimbra backups (auto-grouped).
When I restore my mailbox to a new mailbox with prefix I get error "no such BLOB" on messages older than 1 month (messages on HSM).
Comparing original and restored mailbox, capacity is the same on HSM and message store.
Investigating further I discovered wrong locator values in mysql mboxgroupXY.mail_item compared to original mailbox.
For restored mailbox, ALL records in table, have been changed and point out to default message store instead of HSM store.

Does anyone else having similar problems?
