Understanding Incremental Backups
What is an Incremental Backup?
An incremental backup is a type of backup that only stores the changes made since the last backup. This approach reduces storage space and speeds up the backup process, as only the changed files need to be backed up.
How Does Duplicati Implement Incremental Backups?
Duplicati implements incremental backups by using a combination of file system monitoring and block-level incremental backups. When a file is changed, Duplicati only backs up the changed blocks, rather than the entire file. This approach reduces storage space and improves backup performance.
Disaster Recovery Plan Using Immutable Storage
What is Immutable Storage?
Immutable storage is a type of storage that cannot be modified or deleted once data is written. This approach ensures that data is protected from accidental deletion or modification.
