How to copy data from one disk to another?

[Arvind]

Hello Experts,

I am very new to FreeNAS (a day old). Thanks to a number of guides online, I could install freeNAS and got it up on its feet. Please pardon my ignorance, if I end up asking extremely basic questions.

I installed two hard drives (3 TB & 160GB), and I also have a 4 TB hard drive (where all my data exists).

I would like to keep the 4TB HDD as my primary data store, and keep a backup of my pictures/songs on the 3TB hard drive. So, here are a few basic questions.

• How do I take periodic backups (say once a quarter), from the 4TB HDD to the 3TB HDD?
• When I tried to open the "Plugins" options on the Web GUI, I see the following error.

Regarding the traceback, you shouldn't be getting that. Please create a bug report at bugs.freenas.org that includes the full text of the traceback and post the issue number here.

For some reason, as soon as I posted this thread, the plugins came up fine. :)
I did install Plex, and it works fine.

But I still have that basic question. How do I copy data from one disk to another periodically (automatically)?

If automatic periodic backup is not supported, I can even do it manually. How do I do that?

Search in the manual for "replication" and "snapshots" ;)

Are you disks formatted ZFS? If so you can create snapshots and replicate them very easily. What are your server specs? How much RAM? What does your storage configuration look like?

A tip: you can use the screen capture tool (snipping-tool), copy the image to the clipboard and then paste directly into your post. You don't need to save the capture as a file first.

Thanks a lot for your response @depasseg and @Bidule0hm

@depasseg yes, the disks are formatted ZSF.

Following are the server specs

Server Specs
---------------
BuildFreeNAS-9.3-STABLE-201504152200
PlatformIntel(R) Core(TM) i3-4330 CPU @ 3.50GHz

Storage Configuration

160 GB

Attached is the screenshot of the periodic snapshot, that I have configured. Does it look fine?

How do I use rsync, to copy all data from one disk to another disk (mounted on freenas) ?

How do I use rsync, to copy all data from one disk to another disk (mounted on freenas) ?

this is a pretty good rundown of rsync
