[solved] Restarting RTRR with ftp

[delos]

Hi,

I am using RTRR to backup movies I recorded on my Sat-receiver. This receiver runs on Linux and therefore has an ftp-server.
My question is, what happens when I stop the backup job or when there are new files on the receiver I want to backup.
Does RTRR recognize that files are already backupped to my qnap? Or does it restart the whole job and copy all the files again?
Another question is the Job Policies that can be set. When I click on the properties of a (running) job I can only select "delete extra files" what I
definitely don't want to do.

Regards,
delos

hi
to backup datas, it is better to remote replication, which is able to do incremental job.

Funny thing is I was about to ask very similar question, however your answer is not clear to me. So I'll ask my question in the hopes of a better understanding.

I am using the RTRR (real time remote replication) from a WD MyBookWorld to the QnapTS412. When I set this up I can only use the FTP because the WD NAS does not support the RTRR service. So I set up the FTP server on the WD and choose my remote source and local destination folders on the Qnap as it can push or pull data as required - all good..

Now heres the question, It turns out I cant select the Real-Time settings - Is this because the RTRR service is not available on my remote server thus using FTP? I guess the answer is yes but would like to hear it from someone who knows.

So I select Schedule, and set it to Periodically and enter a time, Is this the time for the first run and will backup when ever possible - when ever that may be? or have I misunderstood the concept ?

In both instances both synchronisation copies files that are new, changed, and renamed from the source folder to the target folder, but what happens to the original backed up files on the target folder ? are they overwritten by the new or are they preserved with the newer being copied. I guess I am asking if it works a little like OS X Versioning, Sorry if this a stupid question but I need to know if I must make other backups in case mistakes are made with the original files, that will filter down to the back up files, which will leave me with no files usable (if you get what a mean) lol

Cheers..

Well I did some tests (should have done them before asking I suppose) and here are my results.

1) Files that are renamed on the source drive are recopied with the new file name - original untouched.
2) Files that are deleted on the source drive are not deleted on the backup drive.
3) Files that are modified on the source drive, and are not renamed are modified on the backup drive, so good file keeping is needed and never re-save using the same filename (which is good practice any how).

hi
with remote replication, there is an 'incremental function', which copies only the files that have changed. there is a also a function called 'delete extra files on remote destination', which implies 'files that are deleted on the source drive are deleted on the backup drive as well'.

you could have a look on the following web page for more information.
http://docs.qnap.com/nas/en/index.html? ... cation.htm

It seems RTRR provides the same options according to that webpage.

in any case, testing is the best

Thanks for the reply, I understand a little better now. These Qnaps are much better than anything WD has to offer

lol some people say they are too basic

in my opinion they are just fine for network under 20 computers.

Hi,

Thanks for the answers but I am still not sure if the system does an incremental backup since I haven't found this option with RTRR.
Will it start to copy all my files once again when I start the backup again?

This is what it does - cut and copied from the NAS :-
Scheduled synchronization copies files that are new, changed, and renamed from the source folder to the target folder according to the pre-configured schedule.

So files that are - NEW, CHANGED and RENAMED are copied. Everything else is ignored. Read my post made on Tue Aug 21, 2012 1:38 pm.

agree with umpa...
first backup copies everything, then it must be muchh much faster.

Hi and thanks for your answers.

But:
Since today, when I restart the RTRR with ftp (even on my other media receivers) I get this log:
2012/09/08 16:54:44 Job [Dreambox Movie ->QNAP] started.

I found the following thread:

But it didn't really help.

did the dreambox password change or the folders be renamed?

I checked. They didn't,on neither of the boxes.

maybe it could be worth testing the login with a ftp soft like filezilla...

[delos]

Thanks, but I did. I also enabled the log of the boxes ftp server (vftpd). The qnap seems to create some directories like /media/hdd/movie/~$#~$ and the log entry says "ok creating directory". I do not find any failure messages in the server's log. I tried filezilla, ftp:// in mozilla, ftp from on box to the other.... All works fine.
