You could take any of your current drives and test this out.
As to your question about existing files, erasure and such, isn't that YOUR CHOICE of settings or actions?
Since I use a simpler copy and paste and never MOVE (bad move, sit, stay) I never find myself without a backup copy.
It appears you think there is some backup/restore application but why would I use such a thing today? Copy/paste is simple, effective and works.
--> Finally, if there is any issue with file systems, I can always boot up my Live CD of Ubuntu to access that.
Computer novice posting:
I've been visiting a friend and using their Mac to save many documents, downloads and screen shots in folders on his desktop. I've also taken and uploaded many photos to existing ones in the Mac's IPhoto storage system.
I would now like to upload all my work and our combined photos from this Mac to some portable device in order to store the documents and images for transport and then upload them to my PC.
I was looking at flash drives, but the combined photos alone are about 70 G's. I think I even tried moving IPhoto event files to a flashdrive and I seem to recall they didn't transfer without my first moving them into a folder on the desktop and THEN transferring them to flash.
I checked out the possibility of portable hard drives - Seagate FreeAgent GoFlex ($39.00) and the Seagate Backup Plus ($79.00). Both seem to be able to upload from a Mac. But, how much of a harangue would it then be to have everything read and downloaded by a PC? I'm sure it can be done, but how?
PS. Related back up question: When a back-up drive moves files from the hard drive, will the Back-Up drive then also erase folders that have been deleted from the computer's drive before a subsequent scheduled backup, OR does the backup drive keep Everything that has been uploaded until I manually erase older items from a backup drive. If the backup tries to mirror the existing hard drive each time it backs up, is there any way to override a backup drive making automatic erasures from the hard drive?
Thank you. Ropple
