The Exiland Backup utility supports four methods of backing up data: full backup, differential backup, incremental backup and synchronization data. A type of backup defines how the data is copied from the source to the destination. With this four backup types you can select the best backup and restore strategy for any kind of your data according to your requirements.
Exiland Backup creates a FULL backup every time. FULL backup contains all the files that are selected to be backed up. If no files have been modified since the last backup, it will not be created.
Exiland Backup will create a FULL backup on the first run. Incremental backup stores all files that have changed since the last FULL or Incremental backup. To restore data from an Incremental backup, you must have the most recent FULL backup and each subsequent incremental backup set available.
Exiland Backup will create a FULL backup on the first run. Differential backup contains all files that have changed since the last FULL backup. To restore data from a Differential backup, you must have the most recent FULL and Differential backups available.
Synchronization data is a mirror backup. It is most frequently used to create an exact copy of the source data. If source files are added, changed, or deleted, all changes will be reflected in the destination folder.
Limitation of the number of FULL backups
This limitation may be set for all backup types except Synchronization.
You may set the number of full backups to be kept (after the number is reached, older backups are deleted).
If this limitation value is set, for example 10, then most old backups will be deleted before creating a new backup.
If you are using the Incremental/Differential backup type, then during the deletion an old full backup of the Incremental/Differential backups created after it are also deleted.
Number of incremental/differential backups between FULL backups
If you have chosen the incremental/differential backup type, you must also specify this parameter. It shows how many incremental/differential backups must be created after creating a full backup. A full backup is created every time this limitation is reached.
