WebIntroduction: This is intended to be a detailed guide for the SDFS file-system. For most purposes, the Quickstart Guide will get you going but if you are interested in advanced topics, this is the place to look. SDFS is a distributed and expandable filesystem designed to provide inline deduplication and flexiblity for applications. WebC. BorgBackup (short: Borg) is a deduplicating backup program. Optionally, it supports compression and authenticated encryption. The main goal of Borg is to provide an efficient and secure way to backup data. The data deduplication technique used makes Borg suitable for daily backups since only changes are stored.
