Sample cron job that emails the results?

Would someone please be so kind as to send me a working cron job file 
that emails the final results (same thing that is output to terminal 
when job is executed via command-line?

Thanks,

which version: OS X?

Hello;

I'm new to both rsync and rsnapshot. Just did what I believe was a successful rsync; now ready to move to
rsnapshot, but not clear to me which version is right for OS X 10.8.2 (Mountain Lion).

can anyone tell me?

thank you!

Re: Rsnapshot rsync/cp-al/ Problems

Due to the help of many of the people on the mailing list (Nico, Ruediger, Ken, Paul…thanks again), I was
able to track down the problem

Due to the fact that this was an NFSv4 mount, there were a couple mapping issues to be sorted out.  However, it
wasn't the 'nobody/nobody' problem that's common, but rather a domain mapping issue.

We were backing up from a <domain.net> to a <lab.domain.net> and the idmapd.conf file couldn't map this
automatically.  Essentially, all that was needed was to qualify the domain and everything worked.

In order to help anyone else out that runs into this problem, make sure that the setting 'Domain = ' is
statically defined and it should be fine. 

Thanks again!

errors are the same.  As for the NFS, it's not NFSv4, but rather appears to be 3.  I created the NFS mount to try
to get around the problem.  I've not seen any SELinux errors in any of the logs, but I could be looking in the
wrong place

Oh, the settings for automounting can get quite strange. But you've
changed the patch to the mountpoint, and not necessarily set SELinux
to allow the new path to work. Also, even if the NFS server is v3, if
you're using automounting, the default on CentOS 6 x changed from 5.x
They're now NFSv4 by default.

You can change this in your /etc/sysconfig/autofs, or in the
particular automount configuraiton. (Ran into this last year.) And
even more fun, if you've got jumbo frames set up and no one mentioned
it for the server, or inconsistently set with the client, you can get
even more fun. (Guess what I did last fall!)

Rsnapshot rsync/cp-al/ Problems

Hi All,

For the past month, we've been running into a real issue in moving backups from one server to another.  This is
specifically backing up mailman (which I know we're using for this mailing list) to an NFS server.

Previously we had NO problem with the backup process and from what I see, the config is EXACTLY the same as it
was before.  The difference being that we've moved from an OpenIndiana box to a CentOS 6 box.  The
interesting thing is that our mailman server is a CentOS 6 box and you'd think it'd be an easy transition.

However, upon running rsnapshot (manually OR via cron…either way), the backup runs into an error

rsync: chown "<path>" failed: Invalid argument (22)

Upon killing the process, I get this error:

ERROR: /usr/bin/rsync returned 20 while processing /var/lib/mailman
rsync: writefd_unbuffered failed to write 7 bytes to socket [generator]: Broken pipe (32)
rsync error: received SIGUSR1 (code 19) at io.c(1525) [generator=3.0.6]

Then, if I don't remove the files that were created but not finished, I get another error subsequently,
which stops ANY more updates from happening:

/bin/cp: failed to preserve ownership for `<path>': Invalid argument

Upon killing or finishing this process:

ERROR: /bin/cp -al <path> failed (result 256, exit status 1).  Perhaps your cp does not support -al options?
ERROR: Error! cp_al("<path>", "<path>")

Now, from the research that I've already done, I made sure that the directory was in the etc/exports and
exported to the correct ip with the options (rw,no_root_squash) and that it was mounted on the client
side.  I originally had rsnapshot just backing up to '/net/≤server>/' instead of mounting it…but
either way produces the same results.

What am I missing?  I really appreciate any help that's given as I'm totally baffled and have tried fussing
with this for hours.

Thanks all, I really appreciate ANY help.

OSX Time Machine versus rsnapshot.

I've been using rsnapshot to back up my home network of mostly Linux
boxen for a bit over 8 years.  Nowadays, my family has been acquiring
more OSX machines, so I setup a Linux box to work as a Time Machine
target.  I used this as a resource:
  http://www.mikepalmer.net/build-a-netatalk-time-machine-for-osx-lion-using-debian-6-0-squeeze/
though there are other similar things out there.  Since all I really
knew about Time Machine was that people had described it as similar to
rsnapshot, so I had figured that it would be rsnapshot-like with the
source fs sync'ed to the remote mount, with hard links to share
unchanged files, etc.  My idea was that I could then use rsnapshot to
pull that onto the big backup server, and the hard links would let me
get away without paying a huge storage cost.  Unfortunately, what I've
found is that Time Machine backs up into a "sparsebundle", which is a
filesystem image in a collection of files.  So, like database storage,
rsnapshot really can't leverage this, and could potentially backup an
inconsistent state for it.

Did that make sense?  If so, has anyone noticed settings or the like
which would cause Time Machine to write files directly on the server
rather than filesystem-in-a-blob?

I'm reluctant to simply export a r/w filesystem from the backup server
for Time Machine to backup into - my entire goal with that server is
that it is pull-only, nothing is ever pushed to it.  So my notion
right now is that I could write a script to manually rsync the Time
Machine data over, perhaps retrying until no data is transferred, and
assume that that's "good enough".

Thanks,
scott

Home backup (notebook) to a small NAS with rsnapshot

Hi,

I am thinking about buying a small NAS (qnap TS-219PII) in order to have a repository of media and also a level
of redundancy to my notebook.

I run Ubuntu and nowadays I run rsnapshot with an external hard drive on a weekly basis and I really like how
rsnapshot works
(although I am no expert on the fine tuning of Rsnapshot itself or Rsync). My notebook has very little
"change" from one week to the other,
so the snapshot takes less than 10 minutes on the (USB2) hard drive.

Now whith the NAS, I would like to run backups there:

- Backup of an Ubuntu notebook via Rsync to the NAS (either via Wireless 802.11n or Gigabit Ethernet)
- Backup of the NAS to an external Hard Drive (via USB3)

What should I consider here?
    1) Mounting the NAS via NFS and run the backup against this (does this even work?)
    2) Install Rsnapshot on the NAS itself and "pull" the data from my notebook (via NFS? Rsync?)
In case of 1, I think the setup would be easier, but what about performance?
In case of 2, I don't want to put a cron or something to run this, I want to have it run manually, but how should I
trigger this "run", since the NAS is going to start it? Via SSH?
    3) when connecting the external hard drive to the NAS ( I plan to do this every couple of months ), I would run
direct from the NAS a rsnapshot.
    In this case I think it will be very straightforward...

I don't care much about security, but if it would be relatively easy to also encrypt the
filesystem/directory on the NAS, it would be intersting.
The "what if the NAS is stolen" scenario.   
Encryption between the NAS and the notebook is useless for me now.

Any suggestions, places to start? I've been reading about it lately and without having the NAS on my hands
yet, I am not able to run tests or check for performance issues.

Thanks a lot for any answer/tips,
Eduardo
