Your OrgPlus Enterprise server should be backed up on a regularly scheduled basis. You will need to work with your IT department to make sure that the OrgPlus Enterprise server is backed up.
The key components required for recovery are machine specific settings (such as changes to IIS configuration or OS configuration) and the OrgPlus Enterprise application database.
After reinstalling (or recovering) OrgPlus Enterprise on a new server, you need to restore the OrgPlus Enterprise application database using database utilities (such as SQL Server Enterprise Manager). You also need to make sure that all changes to machine-specific settings are updated correctly.
