However, duplicity's biggest flaw lies in its incremental model - a chain of dependent backups starts with a full backup followed by a number of incremental ones, and ends when another full backup is uploaded. Deleting one backup will render useless all the subsequent backups on the same chain. Periodic full backups are required, in order to make previous backups disposable.īup also uses librsync to split files into chunks but save chunks in the git packfile format. It doesn't support any cloud storage, or deletion of old backups.ĭuplicati is one of the first backup tools that adopt the chunk-based approach to split files into chunks which are then uploaded to the storage. The chunk-based approach got the incremental backup model right in the sense that every incremental backup is actually a full snapshot. #DUPLICACY RESTORE TO ANOTHER FOLDER FULL# As Duplicati splits files into fixed-size chunks, deletions or insertions of a few bytes will foil the deduplication. Cloud support is extensive, but multiple clients can't back up to the same storage location.Īttic has been acclaimed by some as the Holy Grail of backups. It follows the same incremental backup model like Duplicati, but embraces the variable-size chunk algorithm for better performance and higher deduplication efficiency (not susceptible to byte insertion and deletion any more). Deletions of old backup is also supported. However, no cloud backends are implemented. #DUPLICACY RESTORE TO ANOTHER FOLDER SOFTWARE#Īlthough concurrent backups from multiple clients to the same storage is in theory possible by the use of locking, it is not recommended by the developer due to chunk indices being kept in a local cache.#DUPLICACY RESTORE TO ANOTHER FOLDER FULL#.
