Hello, First of all I'm new to DF. Thanks for the nice install process. It's a quite easy to have DF running. But my concerns are more linked to HammerFS.
My context is the following: - I would like to have a NAS system running on a small machine: 4GB RAM having a celeron CPU of 1.6GHz. - This NAS host +- 700GB of data - I plan to install 1 disk of 1TB in the NAS and keep a second disk of 1TB outside the NAS for DRP reasons. - I'm looking for a solution tackling the bit-rot problem. Concerning HammerFS, I've still read lot of DF manuals, pages, ... : http://lists.dragonflybsd.org/pipermail/users/2015-March/207585.html http://lists.dragonflybsd.org/pipermail/users/2006-June/297848.html http://lists.dragonflybsd.org/pipermail/users/2016-March/228659.html http://lists.dragonflybsd.org/pipermail/users/2015-January/311705.html https://www.dragonflybsd.org/hammer/ So basically, I've understood that I must install DF on a small SSD disk and will dedicated the 1TB disk to HammerFS. But I have some questions: - What must be the setup of HammerFS to solve "bit-rot" ? Should it be Raid1 or Raid5, ... ? Can it be done on 1 physical disk (thus 2 filesystems) ? Should it be 2 PFS in 1 HammerFS located on 1 slice or should I create 2 slices on the disk? - For DRP reasons, how can I perform a backup on an external disk ? (the disk is only connected 1x per month on the NAS). Should I do a "dd" ? should I use the master-slave concepts ? Should I use cpdup ? Many thanks for your replies. Vincent
