Every 2 months or so, Zen Cart will warn me that "The Admin Activity Log table has records over 2 months old and should be achived to conserve space...."
What should I do? Should I click the following "reset" button?
I'm afraid that once I click the reset, all my data, including the clients and order data, will be disappeared.
The simple answer is 'Yes' just click the reset button (you'll then be greeted with another screen to confirm this action).
The longer answer is:
Although it is possible to cause a database corruption with this reset, I've never actually heard of it happening to anyone, and the chances of you losing clients, product or orders data are so remote that it probably isn't worth a second thought.
Having said that though, it is** always **wise to make a backup of the database before doing this anyway. Murphey's Law dictates that if you go to the trouble of making a backup then you'll never need to use it. <smiles>
The other reason for making a backup before hitting the reset is because the chances are you haven't made a backup in the last couple of months anyway, and this really isn't good. You need to get into the habit of making regular backups at least once a week. Most of us with experience will even do this on a daily basis. After all, you never know when that hard drive holding your data is going to fail, and the most recent the backup, the less work it is to recover (and less data being lost forever).
In addition to the database backups, if your site handles Credit Card details then you must export this log data and keep a copy for at least 12 months. You can ignore this step if you don't handle CC data.
If you've never done a Database backup before, then NOW is the time to learn.
