A. I do daily backup of files every 24 hours because I have new files daily. I use my FTP software that does file comparison of server and local copy. In addition to that I have incremental snapshots of the files every week that I rotate out occasionally.
Same thing with database but I'm looking to improve it so in addition to the 24 hour backup I'll have 1 hour incremental backups.
My host does backups too but these are not guaranteed and for any newbie reading this don't depend on your hosts backups unless you're specifically paying for it, even then I wouldn't trust it fully.
B. Yes and I test it occasionally.
Why tape? 1/10th the cost of disk drives... and I like belt AND suspenders.
This is why I like tape cams, storing 10 or 14 GB for 1 hour of video on disk is expensive enough let alone having a backup. At least with the tape it becomes economical to keep the original as a backup and there is no work involved.
