Re: Can I have a folder on my computer mirrored on my NAS?
Cygwin looks confusing. I rather there now be a big learning curve involved to understand how to use a program to backup/sync my computer.

RSync is a command line tool, so I don't understand why you think it is complicated:
From my Linux machine:
Code: Select all
pwilson@pwilsont500:/etc$ rsync --help
rsync version 3.1.1 protocol version 31
Copyright (C) 1996-2014 by Andrew Tridgell, Wayne Davison, and others.
Web site: http://rsync.samba.org/
Capabilities:
64-bit files, 64-bit inums, 64-bit timestamps, 64-bit long ints,
socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
append, ACLs, xattrs, iconv, symtimes, prealloc
rsync comes with ABSOLUTELY NO WARRANTY. This is free software, and you
are welcome to redistribute it under certain conditions. See the GNU
General Public Licence for details.
rsync is a file transfer program capable of efficient remote update
via a fast differencing algorithm.
Usage: rsync [OPTION]... SRC [SRC]... DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
or rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST
or rsync [OPTION]... [USER@]HOST:SRC [DEST]
or rsync [OPTION]... [USER@]HOST::SRC [DEST]
or rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect
to an rsync daemon, and require SRC or DEST to start with a module name.

QNAP wraps their WebUI around "rsync" to obscure you from it, but it is similar on the NAS. You can manage the NAS end by simply using Backup Station. Under Windows you'll need to figure it out. Microsoft doesn't provide RSync with Windows, which is why QNAP wrote NetBak.
RSync has only been around since 1996. Surely Microsoft will provide it eventually.
Check out: rsync Backups for Windows
You can use your NAS, rather than their servers.

Re: Can I have a folder on my computer mirrored on my NAS?
I'm not asking much out of a backup app, apparently just a common feature.pwilson wrote:So lower your requirements, or upgrade your education.
RSync is a command line tool, so I don't understand why you think it is complicated:
I've never used a command line tool, and I don't want to learn how to use one with a program that preforms such an important task that is so critical that the commands be entered exactly, because if they weren't, then I'd be at risk of losing a lot of data (potentially 3TB of data).
In the code section you posted, it was filled with confusing things, and not just all the different commands but once again there's a bunch of abbreviations in the instructions that I don't know, so I can't even follow the part that is there to help people understand what to do.
What do you want me to say? That I'm stupid? Look, I'm not stupid in any means, it's just that this kind of stuff isn't my thing, and I'm no know-it-all like you are. I came to this forum looking for some help, which I thought was a good idea because I've been to other forums and had a great experience there, but now I'm just getting snarky responses.

Did you try that last one I suggested? It is documented etc. Looked like a fairly well written set of instructions. Anyway, you've decline every suggestion so far. I'm afraid I'm out of ideas for you.

I bought a TS-431 with 4x 3TB drives just to have a lot of storage and backup for all the data coming in from my observatory. I want to have a folder on my hard drive in my computer that has a mirrored version of the folder on my NAS. This folder will be large (like 1.8TB) and it will constantly be changing. So instead of, at the end of each day, replacing the whole backup folder on the NAS with the folder on my computer, is there a way that only the changes in the computer folder will be copied/erased from the backup folder? You'd think that doing something like that would be called syncing the 2 folders, but I looked at the Qsync app and I don't think that is the right tool for the job.
Thanks for any help.

I see that you considered Qsync but don't think it is the right tool. I use Qsync for precisely this type of application. I have it on multiple devices with multiple users. It does exactly what you have described, you may want to take another look.
