In the days of DOS the "Map" was called the FAT. Later it was called the FAT32. I don't know what it is called on a NTFS formated drive.
Here, this will explain more: File Allocation Table - Wikipedia, the free encyclopedia
Transfering it to a new HD every time is a little overboard, but it would work. I just suggested a good method to store files long term...
well, good backups are always redundant. That is you have at least 2 different memory devices with the same data on them, and you check them regularly to see if they still work and data is still there. This way you cut in half the chance of losing your backup, because if one memory fails, you still have the other. And by checking regularly you notice failures before both devices fail (so you can make a copy before it's too late).
Of course the more memory devices with an additional backup the less the chance of a failure casing data loss, but I don't see the need for more than triple redundancy.
If you can keep the backups in distant places you avoid losing the data in case something big happens and a backup is physically destroyed (fires, droughts, disasters in general).
You can also use cloud storage services, like dropbox or skydrive, as they will handle backups and whatnot for the data you give them.
hi,
I don't really like cloud storage services, I haven't tried but I don't like the idea its out there. for example family photos from trips and you know...
and I have one memory device with the data i want to backup and I put it in a safe distant place, I only use it for backups.
yes and it is not as safe as backing up with your own device at your place :)
And that's a good one with cloud
Actually, lockpicking their way to your backup drive and imaging it while you are at work or whatever is significantly easier than hacking a cloud-storage server. But I don't see the reason for some random thief to steal your family pics from either the server or your drive. It's all worthless for someone else, and pedos have far more user-friendly places to farm the underage pics they crave (facebook).I don't really like cloud storage services, I haven't tried but I don't like the idea its out there. for example family photos from trips and you know...
I have nothing so confidential, but your needs may be different.
In case it fails you lost backups. At least 2 devices with the same data is recommended, as hard drives can die without reason, and without warning. (and flash drives aren't that better either for long-term storage)and I have one memory device with the data i want to backup and I put it in a safe distant place, I only use it for backups.
Not to say that you need to, just that it's much safer to have redundancy.
They keep backups all the way up to 30 days. If you routinely check that newly modified stuff is working before those 30 days you will catch all such "corruptions" (which are kinda rare imho) and revert to the last working version of that file.DropBox syncs with your folder, so a bad file locally would corrupt the DropBox's file.
What do you [everyone, not just Senteaf] keep your offline backups? How far is far enough away?
Since fires are not a concern for me (brick house) I have two backups, one close to the computer, one hidden somewhere else. If your house can burn down, then having a backup that will survive the house burning down should be a worthy goal.
Plus 18 GB of free dropbox space for a triple backup for the most important things.
I live just outside Detroit, and I will tell you a brick house can burn down!Since fires are not a concern for me (brick house) I have two backups, one close to the computer, one hidden somewhere else.

You mean a house with wooden structure and brick exterior (UK-style)?
Seriously, in my house a fire cannot get from a piece of forniture to the other in the same room, go figure melting the bricks of the structural walls.
