Event Id 1159 While Backing Up Exchange Database
With the following event ID in application log, the information store gets dismounted frequently and hence none of the operation can be performed with completeness: Event Type: Error Event Source: MSExchangeIS Event Category: General Event ID: 1159
Description: Database error 0xfffffd9a occurred in function JTAB_BASE::EcUpdate while accessing the database ““. Some of the users also report that they have discovered unclean backups due to this error. The backups die after a few stage of completion. The problem is critical as at the time you need Exchange Server recovery, having the full and good backup is must. Actually, this problem arises because of large numbers of uncommitted ESE (Extensible Storage Engine) log files in the storage group, which has a limit to keep 1024 transactions log files at a time.
As soon as this number reaches to 1008, the unusual behavior of dismounting along with the mentioned error gets started, resulting glitches in the on-going process of backups. Mostly, restarting the MS Exchange Information store service will solve the problem but the ESE log files created while the backup process may stop the backup software to respond. As a result, the backup does not get completed. Before you could realize this fact, if the corruption in the database occurs; you left to look for the alternatives for EDB recovery. Though Exchange Server gives you an inbuilt utility called Eseutil, but I would recommend not to use this as you have better option in the form EDB repair software. The inbuilt utility work out Exchange Server repair by deleting the corrupted pages, rather EDB recovery software would give you the safe results.
Exchange Server recovery software have intuitive look, read-only nature and superb conducting stuff for complete EDB repair. Stellar Phoenix Mailbox Exchange Recovery can work most effectively to have Exchange Server repair. This uses the powerful scanning algorithms to extract the mailboxes from the corrupted database. This EDB recovery application will give output in the form of PST files. You can get all database objects recovered including e-mails, notes, journals, appointments, tasks and further.
