Practical Theory: Understanding Polling, Extraction and Backup9.4. Automatic and Manual BackupWithin this section, a backup is defined as a file that is generated by the BMDM programautomatically or upon user request. Backup file generation is available only when using anAccess database.The BMDM program stores data from the MPM or BDS in a Microsoft Access or SQLcompatible file. As defined in File Types, an MDB file is an Access database file that storescell and battery readings and setup data. An MDF file is equivalent to an MDB, but for anSQL database. A WinZip ZIP file is a compressed file for backup of an Access MDBdatabase file.When using Access, the working database is automatically saved as a ZIP file at midnight.The number 1 is appended to the file name and the extension becomes ZIP. Backups aremade for three days, appended with 1, 2 or 3. On the fourth day, the oldest backup isoverwritten. On the first of the month, another backup is created, with the month and yearappended to the file name. On subsequent first days of each month, another file is created,again with the month and year appended.The BMDM program cannot back up an SQL database MDF file nor its associated LDF file.The system administrator should institute a process that ensures regular backups of both theseSQL database file types.At any time, to save an Access database as an MDB database file, select File|Save As. Tosave the MDB file as a ZIP backup file, select File|Backup Database.To open a backup file, select File|Open Backup. When the BMDM opens a backup file, itconverts it from a ZIP to an MDB Access database file. Backup does not apply to SQL.To copy an SQL database to the server, attach the database files to the SQL server by typingthe following commands at the command prompt:osql -U sapasswordsp_attach_db @dbname = 'BMDMdatabasename',@filename1 = 'databasepath/BMDMdatabasename.mdf',@filename2 = 'databasepath/BMDMdatabasename_log.ldf'goexitexitWhere password is the password for the system administrator account, which is alber bydefault.Where databasename is the name of the database being copied.Where databasepath is the path under which the database being copied resides.9-3
