Key Concepts

Archive Bit

The archive bit is a file attribute used by many backup systems to indicate whether a file has been modified since its last backup. When a backup operation is performed, this bit may be cleared to signal that the file’s current state has been saved, or it may be preserved so that future backups can recognize changes.

Incremental Backup

An incremental backup copies only the files that have changed since the last backup, whether that was a full backup or a previous incremental backup. Importantly, incremental backups typically clear the archive bit after copying the file, marking it as backed up, which distinguishes them from some other backup types.

Differential Backup

A differential backup copies all files that have changed since the last full backup, regardless of whether they were backed up in previous differential backups. Unlike incremental backups, differential backups do not clear the archive bit, meaning the backup process leaves the file’s change indicator intact until a full backup resets it.

Copy Backup

A copy backup is similar to a full backup in that it backs up files regardless of their change state. However, the key difference is that a copy backup does not clear the archive bit after the backup operation. This preserves the state of file modification markers, allowing the regular backup schedule, which might depend on those markers, to remain unaffected.
