Is there a list of folders that don't needs to be backed up. For example it wouldn't seem to make sense to backup any files that could be restored from the program disk.
Just get a BIG backup drive - they're cheap - and back up everything.
Assuming you're using Windows 7, schedule regular system image backups and deselect all else. Even if you have to replace the entire computer such a backup can get you back up and running with your current setup in mere hours.
Backup Drives are cheap. Online storeage is not THAT cheap. The first 25GB come free with Norton Backup. The next 50GB is $70.00. No mention of pricing if you need more storage. Norton indicates as follows:
Also if you're intending on backing up 200-350 GB of space using an online storage service is not really an ideal scenario for you. The cost of the storage is only one small factor. There is also the cost of bandwidth considering many major ISPs are no longer offering unlimited connection speeds. There is also the time it will take to transfer that much data. You're realistically looking at probably a couple of weeks minimum.
So it really is a problem backing up unecessary files.
There are many GB of files that are copies to your computer when installing Photoshop. Those files could don't need to be backed up because they can be simply reinstalled from the installation disks. There are also a multitude of thumnails, and cache files that PS seems to generate.
I can't tell you which files specifically. That was the point of my question. I was hoping someone could specify which folders have these types of files installed.
Why are you backing your data up to an online service with such limited storage and which you have to pay for again and again?
Buy a couple of 2TB or 3TB backup drives for about a hundred bucks each. Swap them every once in a while and move the other one off site. Schedule a nightly or weekly backup and it takes care of itself. Problem solved.
People try to make protecting their data too complex.
Humans seem to want to overcomplicate everything. On my planet it's all about the simplest, most direct solutions.
I guess we will have to agree to disagree. I don't think that buying several drives, swapping them weekly, then bringing one somewhere else, and repeating the process is a simple or direct solution. As for computer literacy almost every computer columnist recommends on-line backups as an excellent fail safe.
FYI. I am already backing up everything on a local external hard drive, but redundency is the key.
Consider Hurricane Katrina. Using your solution, if I had one drive at my home, and one at my office there is an excellent chance both would have been destroyed!
