Differrential & Incremental Backup
Posted on 2011-03-12
Could anyone confirm if my understanding below of Differential and Incremental backups is correct? Please confirm if what I have stated below is correct?
Sunday: Full Backup is performed.
Monday : File A has changes, so only file A is backed up.
Tuesday : File B has changes, so file A and File B is backed up.
Wednesday: File A and C change, so File A, File B and File C are backed up.
Restoration for Differential: Sunday's Full backup is restored and then Wednesday's backup is restored.
Sunday : Full backup is performed
Monday : File A changes, so only file A is backed up.
Tuesday : File B changes, so only file B is backed up.
Wednesday : File A and C change, so only file A and C are backed up.
