What is a backup set

A backup set is 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.

  • A monthly backup is the first backup created after a month starts.
  • A weekly backup is the first backup created on the day of the week selected in the Weekly backup option (click the gear icon, then Backup options > Weekly backup).
  • A daily backup is the first backup created after a day starts.
  • An hourly backup is the first backup created after an hour starts.

 

Differential backup

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.

 

Full 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.

 

Incremental 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.

 

Single-file backup format

A new backup format, in which the initial full and subsequent incremental backups are saved to a single .tib file, instead of a chain of files. 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format leverages the speed of the incremental backup method, while avoiding its main disadvantage–difficult deletion of outdated backups. The software marks the blocks used by outdated backups as "free" and writes new backups to these blocks.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.
