I am a big believer in backup. The problem that most users encounter with backing up is that they forget to do it, don't have time to do it, or find the backup process too complicated. I completely agree with them. Backing up is complicated, but I have found three applications which will simplify backup for you.
The first program,
Foldershare, is what I am currently using. I recommend
Dropbox for free (2GB) storage, and
JungleDisk if you are a more serious users with
GBs of data to backup.
I have been using
Foldershare for the last couple years. Carla and I each have a copy of this software installed on our laptops. All our documents and pictures are kept in-sync between the two computers. If I add a file to my computer, it will be copied to Carla's computer within seconds. I really like this setup as it keeps our documents in sync and backs up our information to each other's computer. I can access the files from the Internet only if the computers are left online, so that is not an ideal solution.
The ideal solution needs to do the following:
-sync files between multiple computers
-backup files to an off-site place
-allow remote access to the files (even with the computers off)
Dropbox allows you to do all three at once (backup, sync and remote access). You can install the software on multiple computers and keep them all in sync. The free account on
Dropbox gives you 2GB of storage. To store up to 50GB you need to pay $10/month or $99 a year. Sounds reasonable to me. Seems easy to use, though I have not tried it yet.
JungleDisk uses Amazon S3 service to backup your data. Yes, that's the Amazon.com Amazon, so I trust those folks to keep your data secure and available 24/7. You still get instantaneous syncing between multiple computers, data storage to an off-site place and web access to data.
You are charged monthly based on your storage and download/upload throughout the month. Rates are something like $0.15 per GB of storage and something really small for download/upload of data monthly. Cost-wise, I think that
JungleDisk with Amazon S3 is the cheapest backup option for large amounts of data.
I will try out the free 2GB of space with
Dropbox to see if it is worth switching to. My impression is that I will end up using
JungleDisk, as it's price/security/features seem to be the best choice for heavy users.
If you want free, definitely use
DropBox. It will be easy to use, and you'll sleep better for having your important data backed up.
