Improvement of the storage system of a backup server through the evaluation of the Opendedup duplication systems (SDFS) and ZFS

Abstract

Introduction. Introduction. A backup server has a program dedicated to the recovery and organization of information to secure it, trying to prevent the loss of information for both internal and external reasons. Objective. Improve the storage system of a Backup server by evaluating Opendedup duplication systems (SDFS) and ZFS. Methodology. For the development, a test case was elaborated to evaluate the proposed systems. When implementing standalone license tools like Virtualbox, Bacula, etc., the installation of deduplication solutions is done under a virtual Linux Mint 19.1 distribution with Virtualbox, installed on a single physical machine, and also a Bacula server on which the deduplication is done. Backups. it will be created and stored in our own environment with SDFS and ZFS mirroring. Results. The SDFS system had 50% compliance in the initial comparison against 81% for ZFS, in addition SDFS obtained 4 points of use in the comparison after operation, while ZFS only had 12 points of use, finally SDFS increased 2 points in comparison of functionalities surpassed by the 5 points of ZFS. Conclusion. ZFS offers better performance in terms of storage optimization on the backup server, despite the difficulties encountered during installation, the deduplication method is superior to that offered by SDSF based on cache capacity. We recommend creating backups in incremental file format because with this type of data the percentage of duplicate exceptions is more pronounced, relative to the underlying data.
