Database Backup And Recovery
APO
automatically creates backup copies of up to three different versions of your
database in the same directory where the current database is placed. These
copies are named with the ".old" extensions as illustrated in the
following example:
mydb.mdb
mydb.mdb.old
mydb.mdb.old.old
mydb.mdb.old.old.old
All the
"old" files are re-built every time APO is started, if the date/time
of the most recent "old" file is more than 12 hours older than current
date/time.
It is
important to save copies of your databases each time you have done important
changes or additions. Back up copies should preferably be placed on a different
disk, because your disk can stop functioning in any moment, without warning, and
you may lose all your data. The database could also be corrupted as a
consequence of a blackout or problems with the Windows operating system.
If you
need to fall back to a back up version of your database, just copy it in your
preferred directory and select that database file at APO start-up.
You
can also ask the program to make a copy of the current database with a given
name and put it in a given directory (see "Save database as..."
command in the Main Context
Menu).
