I'm realizing more and more that backups are critical (duh). But what is the best way to do it?!! I've been trying a bunch of methods, never feeling 100% (or even 50%) that it was right and we were secure.
This is concerning 20 - 40 GB of data and we have DSL
too much for online storage? Connection time and costs?
Tape drives -for that amount of storage - too expensive?
External hard drives? how large and farther down here, is the question of how to back up? a 300 GB external drive would have 1 copy? Or several backups?
METHODOLOGY / SOFTWARE?
I wrote a batch script that xcopy c:\data to either an external drive or to an internal drive in the building (internal logic - don't bother to take it home but fire / theft hitting both parts of the building are even rarer than theft / fire at all).
The batch would loop thought 5 backup folders (so 5 nights of data). But it's a dos batch - no notification that there was a problem
how many instances of backup would you keep? the above method keeps 5, and then it loops over again.
1 issue with the simple xcopy is that if a file is moved from foldera to folderb, on the backup it is now in both places - the xcopy doesn't sync... which in a way is good - if the file was deleted from a, you don't want it to be deleted from the backup? but then the backups are not true copies of the hard drive in the case of needing to do a restore of all the data....
yeah, there's lots of apps out there that do backups... I am looking for answers to the more etheral questions of how many backups / do you do full backups all the time / what do you think of the xcopy / what do you backup to / etc.
thanks! Points are awarded for any ueseful advice... there's no wrong answers!
