>Dropbox is not a backup. Dropbox is a file sync service with some limited backup features
Agreed. Dropbox is more of a consumer disaster recovery solution than a backup solution. If your computer hard drive dies, you lose zero data. On the sysadmin side of IT, we distinguish between backups and replication. Backups have retention and are usually slow to recover from if you need to recover large amounts of data. Replication is often used to maintain a "ready to go" copy of the data. If a server dies a horrible death, boot the standy replication partner and we are back online. Dropbox can work this way of you have it installed on two PCs.
If your data is important, don't leave it to any single service to protect it. If you have truly important data, go ahead and use online backup/sync services, but also make your own point-in-time backups to avoid the accidental deletion of a file you only look at once per year. A cheap USB hard drive that holds monthly or quarterly backups, kept in a safe deposit box, will suffice for most people as that third line of defense.
