The ES 500 is a great little backup unit. Easy to use, long battery life (about 25 min. with a desktop PC plugged in; 2 hrs. with a notebook PC plugged into it). It includes full surge protector capabilities, so you won't need to buy another one of those.
right now the chatter is to run weekly fulls and keep them for 6 weeks and the log backups also only for a few weeks. then run another full backup during the month and keep that one for 6 months. i still like tape backups over disk and this is worse than the old schedule of keeping every weekly full for 5-6 months.
