incremental backup
An incremental backup is a data protection method that saves only the changes made since the last backup. For example, if you back up your files on Monday and then make changes on Tuesday, an incremental backup on Tuesday will save only the new or modified files. This approach is efficient because it reduces storage space and speeds up the backup process. However, to restore everything, you need the last full backup and all subsequent incremental backups. Thus, it balances time, storage, and recovery needs effectively.

An incremental backup is a data protection method that saves only the changes made since the last backup. For example, if you back up your files on Monday and then only add or change a few files on Tuesday, an incremental backup on Tuesday will only save those new or modified files. This approach is efficient, using less storage space and time compared to backing up everything each time. It allows for quicker restorations, as you only need the last full backup and the incremental backups that follow to retrieve your most current data.
