Backing Up Your Observing Log
Knightware recommends that you backup your observing log and user data periodically and before applying a software update to Deep-Sky Planner. You should also compact your database periodically (File | Compact Database) to improve program performance and minimize the amount of disk space required by the database.
Why backup?
Deep-Sky Planner uses a database to store catalog data and user data - both your observing log and observing locations. When you make changes to locations using the Location Manager, or add equipment and/or observations to the observing log, you are changing the database. Although Deep-Sky Planner has extensive error handling and transaction control in its handling of the database, problems can occur resulting in a corrupted file. Keeping a backup is a safeguard against losing this data.
Backup Method 1
The best way to back up your observing log and user options is to use File | Backup to save your data to an external storage device - perhaps an external hard drive or flash drive. You can use File | Restore to extract the data and copy it into your database, either on the same computer from which it came or another.
Backup Method 2
Another way to back up your database is to make a copy of it and save it to an external storage device. The database is usually found at C:\Users\<username>\Documents\Deep-Sky Planner 6\Database\Dsp.mdb. This method requires over 325 MB of storage space and does NOT include a backup of your user options.
