[HOWTO] Daily incremental backup with rsnapshot

[crushdepth]

Error messages are logged to the rsnapshot logfile. There is an example shell script to send job results to email here. I am not sure if this would work on a QNAP or not.

Maybe someone whose good at shell scripting could have a go at this

[efaden]

That's what I was going to do. The problem is that the QNAP doesn't have mail.

[efaden]

I think I figured out how to send email.... I am working on a script and will post what I get. Thus far...

Add the alias in to /etc/config/ssmtp/revaliases...

Code: Select all

admin:qnap@blah.com:mail.blah.com:25

Then you can use ssmtp to send the mail... here is my test script...

Did you manage to get it to email error messages to you?

[efaden]

Yeah... if you do what I said above I got it to email out messages....

[efaden]

Got a script all done.... I have rsnapshot setup as per the guide.... and then ....

I think it works.......

Whoops... log getter was wrong. Either need to update the script to grab yesterdays date... OR change the crontab to run BEFORE midnight...

crushdepth, great job. Many thanks!
I do it successed on TS-459 pro for remote backup under your guide step by step.

[crushdepth]

Welcome

I hope one day rsnapshot will be included in the QNAP firmware. Being able to step back in time and recover a specific version of a file is extremely useful.

+1!

i also suggested this once to qnap... and adding a nice web ui for it would be even better. hope to see this or a similar function soon.

[Eduardo]

Using rsnapshot for the last two months. It works flawlessly.
I recovered an important file two weeks ago, and saved some hours of working.
Thanks to Crushdepth!

I'm having a bit of trouble setting up rsynch/rsnapshot. I have two servers QNAP1 and QNAP2. I have a directory in QNAP1 called DocumentControl. I am wanting this directory to get backed up daily and I am using the following backup command:

backup admin@qnap1:/DocumentControl/ DocumentControl/

When I run "rsnapshot daily" I get the following error:
rsync: link_stat "/DocumentControl" failed: No such file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1508) [Receiver=3.0.7]

Sure enough... if I use putty to log onto QNAP1 and do a "CD /DocumentControl", my directory is not there. Where is the DocumentControl directory actually located? I created it as a new folder off the root that is visible when using my browser (Internet Exporer) and going to \\qnap1 (the same place I see Public, Qdownload, Qrecordings, Qweb, etc).

Thank you.

****UPDATE****.... nevermind... I found it under SHARE.

[hayedid]

Hi. I had rsnapshot configured with the following:
backup admin@qnap1:/share/DocumentControl/ DocumentControl/

I put a text file (text.txt) in my DocumentControl directory and ran "rsnapshot daily" I expected to see "daily.0/DocumentControl/text.txt" in my snapshots folder. Instead, I saw In my snapshots folder, I went to "daily.0/DocumentControl/share" and there was no "text.txt" file backed up.

I then tried the following with better results, but very deep nesting.
backup admin@qnap1:/share/MD0_DATA/DocumentControl/ QNAP1/

Doing this created the Text.TXT file in the following directory
\\qnap2\snapshots\daily.0\QNAP1\share\MD0_DATA\DocumentControl

Why do I have to use MD0_DATA when I can see the files when I go to /share/DocumentControl? Why does the backup contain "QNAP1\share\MD0_DATA\DocumentControl" directory instead of simply "DocumentControl"? I do understand that its giving the fully qualified path, but it's a lot of nesting that, I find to be inconvenient and unnecessary. Is there any way to prevent this?

Thanks.

It is still hard to believe that Qnap hasnt implemented this realy crucial function

Not that I know of. I think you need to use the fully qualified path, which includes MD0_DATA as you said.
