Next I manualy start Full backup of this Public Folder. It finish succesfully with status 0. Snapshot was successfull too.

Next I manualy start Differential Backup and it fail with code 130 and same shapshot errors.

All Mailbox Databases backup successfully with full and difference backup. This issue affect only Public Folder.

What may be wrong with  Public Folder differential backup?

Status 130 is usually caused by something on the exchange side, here it seems to be a problem with the VSS snapshot of the Public Folder. You will probably need help from the exchange administrator and maybe the OS administrator if that is not the same person.

There are also a lot of technotes about status 130 and what can cause it.

Solved this. Previous admin forgot uncheck circular logging on this public folder database, after disabling circular logging and made new full backup, diff backup was successfull.
