8.5 Archiving Files
Microsoft Access databases tend to grow fast. Databases above 0.5 Gigabytes can drastically slow down
file operations.
To avoid enormous growing files, you can either periodically change the target database, or use the Upload
Scheduler’s file archiver to automatically move older data to archives.
The Upload Scheduler archives files upon a weekly, monthly or yearly schedule. When archiving data, a
new database is created to where older data from your present database with the expired archiving date
is moved.
An archive file keeps the original database name to which the date of the oldest database record is added,
so you can easily identify your archives and work with them as you work with a regular database.
To provide a schedule for archiving files:
1. When defining a schedule for uploading files from your meter, click on Configure or double click
on the site row.
2. Click Auto Archive.
3. Check the Enable box and select a periodic schedule for archiving your files for this site.
4. Click OK.
To avoid archiving partially updated data, archiving is performed in a day after expiring a scheduled period
and not before 2 hours a.m.
