SUMMARY

Copying data to CD or DVD is the least expensive method, but it is limited in size and must be done manually and can take time.

Internet-based Online Backup solutions don't require any hardware or media and for a monthly fee offer a place to copy data on their servers. It is limited is size and can take a long time to transfer data, but the backup automated and is stored offsite automatically.

Copying data to an external USB disk drive is the least expensive way to copy large amounts of data. Although they can be taken offiste the are more buky. Also, decause they are mechanical in nature, they are subject to failures and fragile.

Tape drives are the best way to store large amounts of data, automatically at night, but the tapes must be swapped and taken offsite manually.
