How many computer users rely completely on application wizards?  I have nothing against application wizards, in fact, I do recommend users to make use of these when they are using new applications and lack experience with that application. However, wizards most often set certain parameters to default values rather than adding an extra screen or step to allow the user to verify some advanced parameters! Wizards are tools with a sole purpose of making your life easier and hence, would assume many assumptions! Hopefully, safe assumptions rather than deceiving ones! But, is this ok with backup applications? Without debating whether this is correct or not, I would prefer to share with you the most important parameters to look for when performing a data backup:

1. The application or wizard allows you to set verification of a backup job – tick the verify check box
2. Enable logging features – make sure you know the log files location
3. The application allows you to encrypt backed up data with a password if your destination location is a remote storage host or removable media such as, pen drives – dual password entry text box
4. Enable job status features such as, completion reports – check for failures or warnings

If these options are not presented to you in the application wizard then go and look for them before you start the job. Although, the verification mechanism was more intended to verify data integrity when backing up to tape media, it is still a useful check for all kind of media.

Another important task that I recommend you to perform from time to time is a restore test operation. Select a previous backup set and perform a restore operation to an alternate location (if you restore to the original location, remember you would overwrite your recent files with older ones). After a test restore operation check that the restored files are not corrupted such as, opening a word document or spreadsheet and verify that the data is complete and accessible.
