How can I backup Exchange Incremental with enable circular logging?

Created: 05 Dec 2013 • Updated: 09 Dec 2013 | 2 comments

Now Backup incremental job was failed.

Error : 

V-79-57344-33943 - Snapshot Technology: Initialization failure on: "Microsoft Information Store". Snapshot technology used: Microsoft Volume Shadow Copy Service (VSS).
Snapshot technology error (0xE0008497): You cannot perform incremental and differential backups because Microsoft Exchange is configured for circular logging. To perform incremental or differential backups disable circular logging.  Additionally, you cannot perform no-loss restores if you keep circular logging enabled.

when I disable Circular Logging in Exchange, mailbox was damaged because lost some log file then Exchange mailbox was dismounted and can't mount mailbox.

Full backup in this job is success.

but before I recreate this job it can success backup both full and incremental. I think I configure same old job.

I recreate job because I test more backup job and storage is low. Then I clear all backup database.

Then, Can I backup incremental with enable circular logging? How?

Sorry, My English is not good.

Hello Sonkub,

    To take Incremental backups of Exchange, Circular logging has to be disabled. refer to the following doc: : How to disable circular logging in Microsoft Exchange so that differential or incremental backups of Exchange Storage Groups and Databases can be performed.



Hope this piece of Information Helps you... and if it does then mark this response as Solution....!!!

If you read the effect section of this Microsoft article you will realize that no backup product can do what you are trying to do
