A group of backups to which an individual retention rule can be applied.
For the Custom backup scheme, the backup sets correspond to the backup methods (Full, Differential, and Incremental).
In all other cases, the backup sets are Monthly, Daily, Weekly, and Hourly.
If a weekly backup is the first backup created after a month starts, this backup is considered monthly. In this case, a weekly backup will be created on the selected day of the next week.
A differential backup stores changes to the data against the latest full backup. You need access to the corresponding full backup to recover the data from a differential backup.
A self-sufficient backup containing all data chosen for backup. You do not need access to any other backup to recover the data from a full backup.
A backup that stores changes to the data against the latest backup. You need access to other backups to recover data from an incremental backup.
A machine that is backed up by an agent installed in the operating system.
A backup format, in which the initial full and subsequent incremental backups are saved to a single .tibx file. This format leverages the speed of the incremental backup method, while avoiding its main disadvantage–difficult deletion of outdated backups. The software marks the blocks used by outdated backups as "free" and writes new backups to these blocks. This results in extremely fast cleanup, with minimal resource consumption.
The single-file backup format is not available when backing up to locations that do not support random-access reads and writes.
A virtual machine that is backed up at a hypervisor level by an external agent such as Agent for VMware or Agent for Hyper-V.
A virtual machine with an agent inside is treated as physical from the backup standpoint.
