Which is better for data backup, USB Flash Drive or Memory Card?

Carbonite works well, but yes - expensive.

For local data protection, you can purchase a relatively inexpensive 1TB external drive and backup to that. The built in Windows backup software will do, or you can grab a good free option like Cobian Backup. Keep in mind that external backup drives can have the half-life of a mayfly. I don't leave mine connected for much more than doing backups.

Don't do thumb drives. If your goal is long term storage they *do* have the half life of a mayfly.

(EDIT: Let me be 100% clear here - SD, thumb drives and other types of solid state memory drives/cards degrade over time. Repeated read/writes to these drives eventually reduce their usability. When they are close to full, their performance stinks. Sometimes just inserting and removing them can cause catastrophic data loss. It's not an everyday occurrence, but I mention this because I've seen it happen more than once. For random storage, who cares? But once you bring the word "backup" into this, it's a different situation.)

If your system supports it, consider adding a second HDD as a RAID 1 mirror. This is not a backup, but a redundant drive that protects your data from the failure of a single disk. If your hardware does not support RAID, then scratch that.

For cloud protection, you can find a free option that will do for a small amount of files - usually 5GB. Look at Mozy, SugarSync, DropBox, Google Drive (15GB), or Windows Live SkyDrive (25GB). They might not be all automatic sync storage, but it's free storage online.

Using email as a poor-man's backup will work, but keep in mind that free email accounts can be subjected to a random banhammer. It's happened to me once with an account that I rarely used, but I had to pray to the Google Gods to get them to bring it back from the dead.

How much you are willing to pay and how much risk you are willing to accept might depend on how put out you'd be if that data was forever lost.

Memory Card Vs Flash Drive

Emailing yourself is a good idea if no one is after you or trying to hack your account.

But now a days, in Russia, in the Kremlin, the Russian army makes their reports on paper. They have moved to type writers for if they have to make any top secret document. Because the internet is completely owned bu the Americans, and anything can be hacked if your computer is connected to the internet of if your computer has a wifi or Bluetooth attached to it

So i would recommend that don't be afraid to print on a paper and hide the paper in something safe and lock it up

A USB can get lost and a memory card can get corrupt and sometimes the data can't be retrieved because the memory card gets too damaged!!

If you're comparing a usb memory stick versus a usb hard drive, the usb hard drive the way I would go. If you're comparing a flash memory card (i.e. secure digital size) versus a USB memory stick, I'd go with the USB memory stick. One thing to note: Backing up to a USB memory stick is usually slower than using a USB hard drive. Also USB memory sticks are small and easy to lose - I've personally misplaced two of them. A USB hard drive is generally larger and faster.

For offline use a good old DVD disc burner with a quality blank DVD. For on-line I use Copy.com which has no file size limit and gives you free 15 GB (more than most others). The good part is that you get a 5GB bonus (for 20GB total) by using the referral link below. I will get a 5 GB referral bonus as well (thanks!). All you have to do is sign up through link below and download their free app (works just like Skydrive) then confirm bonus through the email link they send you. You then get 15+5 GB with no file limits. Great for storing an on-line version as backup to off-line backup. Use my referral link below:

How about use a USB save dongle to dump all of what needed information? It's easy and convenient.

Asigra works perfect and its dead cheap for the technology you get!! i am using it the last 3 years to backup online my sensitive and useful data and the best thing i centalize now all my backup of PC, NOTEBOOK, TABLET AND MOBILE PHONE TO ONE LOCATION.

Neither - a portable hard drive is probably what you want, it'll last for a long while and, provided you encrypt the files, is very safe.

The following is a list of different available Backup Software programs:
