Free backup software for Microsoft Windows featuring compression, encryption and automatic incremental archiving. Backups can be saved to CD, DVD, USB memory stick, a second hard drive (internal or external), etc. It supports long file names (32,000 characters) for all backup routines.
"Cobian Backup is not an usual backup application: it only copies your files and folders in original or compressed mode to other destination, creating a security copy as a result. So Cobian Backup can be better described as a "Scheduler for security copies". Cobian Backup supports several methods of compression and strong encryption. "
Backup Types: Full, Incremental, Differential, Dummy
Differential
The backup software looks at which files have changed since you last did a full backup. Then creates copies of all the files that are different from the ones in the full backup.
If you do a differential backup more than once, it will copy all the files, or parts of files that have changed since the last full backup, even if you already have identical copies of those files in a previous differential backup.
For restoring all the data, you will only need the the last full backup, and the last differential backup.
Faster to create than a full backup.
Restoration is faster than using incremental backup.
Not as much storage needed as in a full backup. Restoration is slower than using a full backup.
Creating a differential backup is slower than creating an incremental backup.
Incremental
The backup software creates copies of all the files, or parts of files that have changed since previous backups of any type (full, differential or incremental).
For example if you did a full backup on Sunday. An incremental backup made on Monday, would only contain files changed since Sunday, and an incremental backup on Tuesday, would only contain files changed since Monday, and so on.
