Please help on this.

Re: IDB backup problem

hello

 

i would suggest doing an idb maintenance. basicly purge old data in the idb, export and then reimport the data. during this time, no backup jobs can run.

have also seen that a heavily fragmented drive where the idb resides on, does create such effects you describe.

 

regards

Re: IDB backup problem

Hi

 

Make sure not Backup and Restore Jobs are running. Then stopp dp services (omnisv -stop) and make a copy of the omniback\db40 and omniback\config folder as a backup.

 

Start dp Services (omnisv -start)

Run Purge with "omnidbutil -purge -filenames -force"

-> you can monitor the process in dp gui. if you want to stop purge, use "omnidbutil -purge_stop"

 

if purge is completed run db export. create empty direcotry first (for example e:\dpdbexport\mmdb and e:\dpdbexport\cdb). after that, export idb

omnidbutil -writedb -mmdb <path> -cdb <path>

 

after export, just reimport idb with

omnidbutil -readdb -mmdb <path> -cdb <path>

 

after that, run omnidbutil -fixmpos

 

if everything went well, run omnidbcheck to verfiy if idb is fine..

 

regards

Re: IDB backup problem

100Gb is quite large.
You may want to start thinking about
    - recycle or export old media, which you no longer need.
    - reduce protection on some of your backups.
    - start a second cell, to take some of the load off this one.

There are some other purges that might help detailed in knowledge document KM744051
