I have seen a number of threads recently about rsynch, zfs replication, and hardware failures. This got me thinking about my own backup strategy which isn't very good at the moment. In addition to my FreeNAS systems listed in my sig, I also have a ReadyNAS NV+ v2 (4 bays) with RAID5 of 4 x WDC WD20EFRX-68AX9N0 (WD Red 2TB NAS Hard Disk Drive - 5400 RPM). That one mostly does some CIFS shares and runs my Logitech Media Server (because I have been too lazy to try and do it on FreeNAS). This one has (alleged) support for NFS and rsynch, but my experience trying that tells me that the write process is being handled by a 1 armed, 1 eyed retarded squirrel using a chisel and stone tablet. :-( I killed the rsynch process after 4 days. Ugh!
Below is what my primary pool looks like:
I don't have my secondary server on all the time because it is in my office, and it with the D2700 external array are too loud and add significantly to the room heat. My rate of change on files is pretty low other than the 3 VM's I run all the time (FreeBSD mail server, Vcenter, APC powerchute appliance), so I really can't justify anything too crazy. I am working on increasing the space in my secondary FreeNAS because neither that or the ReadyNAS has enough space to back up everything on the primary. I don't think ZFS replication will work for me because I would likely want to back up the media files on the ReadyNAS to secondary FreeNAS as well. I think the backup would need to be something I can kick off manually since I won't always have the backup target up all the time. Mainly I am looking for some tactical guidance from the group to meet my limited needs. Rsynch seems like my best bet, but it was kind of slow. That might just be that the first pass is like that.
Thanks in advance.
