I would like to know if I choose the repair option during BOXI 3.1 installation will it hamper my previous data. I mean will it also flush my report published in BOXI.
do I need to take aback up. If yes how to take a backup.
any help is appreciated.
Normally this should not affect your content but I would recommend to do a backup.
The best ay to do a backup is to stop all BOBJ services (SIA) and do a backup of the repository database and the file repository (this resides normally under the Filestore directory unless you have configured this otherwise).
