2. Incremental backup - Wikipedia

   en.wikipedia.org/wiki/Incremental_backup

   Incremental backup. An incremental backup is one in which successive copies of the data contain only the portion that has changed since the preceding backup copy was made. [1][2][3][4] When a full recovery is needed, the restoration process would need the last full backup plus all the incremental backups until the point of restoration. [5]

3. Backup rotation scheme - Wikipedia

   en.wikipedia.org/wiki/Backup_rotation_scheme

   A backup rotation scheme is a system of backing up data to computer media (such as tapes) that minimizes, by re-use, the number of media used. The scheme determines how and when each piece of removable storage is used for a backup job and how long it is retained once it has backup data stored on it. Different techniques have evolved over time ...

7. Backup software - Wikipedia

   en.wikipedia.org/wiki/Backup_software

   Backup solutions generally support differential backups and incremental backups in addition to full backups, so only material that is newer or changed compared to the backed up data is actually backed up. The effect of these is to increase significantly the speed of the backup process over slow networks while decreasing space requirements.
