For its backup needs, DILC is initiating a network-attached storage (NAS) project. The goal of the project is to deploy inexpensive, reliable, robust, scalable backup system for DILC's use. It only uses commodity, off-the-shelf parts and free and open source technologies.
Specs
The system
- uses NAS4free
- embedded installation (USB)
- protocols deployed SFTP, NFS, Samba, AFP, RSYNC
- intranet only
- ZFS
- "hot" expandable (additional 2TB hard drives can be added thereby expanding the current CONTIGUOUS volume; the limit of the number of drives is determined by the number of SATA slots available in the motherboard)
Deployment
- Remote Site B: initial rollout: 4TB contiguous space, using 2x2TB commodity hard drives (expandable to 6x2TB; there appears to be a limit to hd size - 2TB - before getting errors). "Hot swap" addition of 2Tb drive was done on 8 June 2013 bringing the total size of the contiguous drive to 6Tb.
Remote Site B backup is meant to cope with backup requirements that now exceed the capacity of Remote Site A (as of 21 April 2013):
By far DILC file size appears to grow at the rate of about 1Tb a month.
