Hi guys.
Although this runs as a dry run, and also runs without error MANUALLY

32 2 * * * /usr/sbin/rtc -s
30 2 2 * * /usr/sbin/rtc -c
59 1 * * * /usr/sbin/daylight &
5 2 * * * /mnt/HD_a2/ffp/bin/rsync -rlptDv --delete /mnt/HD_a2 /mnt/HD_b2 >> /mnt/HD_a2/ffp/log/rsync.last.log 2>&1
5 2 * * * /mnt/HD_a2/fun_plug.d/bin/rsync -rlptDv --delete /mnt/HD_a2 /mnt/HD_b2 >> /mnt/HD_a2/fun_plug.d/log/rsync.last.log 2>&1

It will not run automatically for me now. I can't seem to find out how. Any thoughts as what I have done wrong. I have posted the crontab -l above, and it now refers to the funplug and also ffp directories after I was trying to "redo" the settings when trying to fix this prob. When I vi the file (FFP) as described however only the FFP line is actually there, no sign of the fun_plug.d one. Actually it may be I have created a fun_plug.d version hence editcron.sh file? Should I delete it? Is it interfering?

I have also made sure I have followed the a+x command correctly.

So Basically it works manually but not scheduled and running properly.

As this works so well I really would like it just to copy across automatically, and previously I have had it work properly.

I have added append rather than replace log file option. (but can't find the log file as described).

Any help appreciated,
Regards
H69

hastings:
It sounds like you might have multiple executables in the start folder adding crontab tasks. Also, what version of fonz' fun_plug do you have installed? Are you aware that there are two different folder structures depending on the version?

Here are a couple commands that could help us get to the bottom of this:

Code:

ls -l /mnt/HD_a2/fun_plug.d/start
ls -l /mnt/HD_a2/fun_plug.d/log

ls -l /mnt/HD_a2/ffp/start
ls -l /mnt/HD_a2/ffp/log

Hi Halfsoul,

I run FFP 0.5, so the fun plug directory was just a cut and paste error (when I cut vi in front it just ran automatically, then not knowing much I must have saved the fun plug directory before I realised I was in the wrong directory!........noob. I am still trying to work vi out with right clicking etc, I'll get better.

I ssh into the DNS. and login as root when I have run these commands initially and also what I paste below.

OK, let's take a look at the contents of your fun plug dir. Type this:

Code:

/ # ls -l /mnt/HD_a2/ffp

One of your entries should look similar to this:

Code:

drwxr-xr-x    2 root     root         4096 May 16 19:51 log

If not, create a log folder:

Code:

/ # mkdir /mnt/HD_a2/ffp/log

.... and then restart your DNS through the web interface and check the crontab -l results again.

Well, that doesn't make much sense to me. Have you changed the ffp dir permissions?

Code:

ls -al /mnt/HD_a2/ffp

or

Code:

ls -l /mnt/HD_a2

hastings69 · 2008-05-30 01:21:19

Not intentionally. I really think not, but I can't be 100%

So in my infinite noob wisdom I chmod 700 -R ffp......with an output of
drwx------ 2 root root 8192 May 24 03:34 bin
drwx------ 5 root root 4096 May 28 15:26 etc
drwx------ 4 root root 4096 May 24 03:34 lib
drwx------ 2 root root 4096 May 24 03:34 libexec
drwx------ 2 root root 4096 May 24 03:34 sbin
drwx------ 13 root root 4096 May 24 03:34 share
drwx------ 2 root root 4096 May 24 03:47 start
drwx------ 2 root root 4096 Apr 19 14:39 tmp
drwx------ 5 root root 4096 May 28 15:05 var

I now can't ssh into the box (familiar problem with me and permissions with this) but am telnetting in, after I stuffed with the ssh permissions AGAIN (I am really dangerous with that!) I am learning by trial and error, error error...... all my uninformed efforts.

I can easily start from scratch again with FFP, and keep my data/media files, is this the best rather than consume vast amounts fo everyones time for individual file permissions? However this is the exact reason why I had to reinstall fpp from changing permissions last time and ssh not being happy with it. And I expect to be facing the same problem that it won't rerun. Are there hidden files that I didn't delete last time reinstalling FFP within FFP that may be affecting it all?

Cheers

It might be best to reinstall ffp from scratch. Looking through my ffp dir, there is quite a variation in permissions so it wouldn't be "easy" to restore the original permissions. Of course, it wouldn't be difficult, it would just take quite a bit of time.

I think your SSH no longer functions because of the permissions/executable situation, and it sounds like the VolA to VolB backup isn't working because you don't have a log dir. Not sure why that would prevent it from running, but I though someone earlier in the thread mentioned having a similar problem. Plus, the logging is the only difference between your commands that do work (dry run & on-demand) and the one that doesn't (scheduled).

However, I also wonder if having the two simultaneous entries in your cron has something to do with it. If you do re-install ffp, I would be interested to know you end up with as far as scheduled tasks.

Good luck!

marinalink · 2008-06-01 00:12:30

For those who don't know rsnapshot, have a look here Rsnapshot for local and remote backup,

It does also (incremental) backups and rsnapshot is now quite stable and very well tested.

Just a hint,

Solo100 · 2008-06-12 20:43:35

Hi all, newbie here, so please, be gentle... In February I have installed fun_plug .3 and followed the disk copying procedure described here. Recently I had rights problems with the copied files and seize the occasion to install the new firmware 1.05 and new fun_plug ffp .5.

So after a couple of problems, the ffp is now installed and I can telnet into the unit. But weirdly, when I connect I don't have the Busy Box introduction. Only:

/ #

So I typed the first line and here's what I get after doing ENTER:

/ # vi /mnt/HD_a2/ffp/start/editcron.sh

~
~
~
~
~
~
~
~
~
~
~
~
~
~
~
~
~
~
~
~
~
~
I /mnt/HD_a2/ffp/start/editcron.sh [Modified] 1/1 100%

after that if I type "a" (or anything else) I still get "locked" in this box, no flashing # sign, no nothing... and if I go back to check on my volume_1/start , the file is not created. Is there another thing I have to do to activate vi with ffp .5 ? Or how can I get out of this to enter the "copying script" ?

Any help will be a0preciated, thanks in advance

Solo

drak0 · 2008-06-13 02:14:23

Solo,

You need to read a tutorial on how to use vi.

http://www.viemu.com/a_vi_vim_graphical … orial.html

hastings69 · 2008-06-13 02:52:57

Also I don't get a busybox intro with ffp 0.5, so I just continue. I think that is a change from ffp 0.3 and ffp 0.4, I think it is fine and normal. Don't worry about it.

Make sure you follow the instructions EXACTLY letter for letter, it worked for me if I did it EXACTLY. I am a newb and have got it to work, I didn't need to know VI except for following these instructions exactly, if redoing it doesn't work please repost, someone here can help.

Solo100 · 2008-06-18 05:26:17

Thanks guys, after reading yours posts and even trying to figure out a bit about "vi", I definitely made some progress...

In fact, it seems the first part is ok as I created the editcron.sh file and what is listed seems the same as what it should. My problem now is that I seem unable to make this file executable.

I entered the script correctly at the # prompt and when I do the crontab -l command, I don't see the new script listed, only the 3 original ones, and obviously the backup doesn't execute... and I did reboot after doing the command.

Should I have do some vi command before entering the "chmod a+x /mnt/HD_a2/ffp/start/editcron.sh" code after the putty # sign, or after?? Or is there anything I missed that you can see?

Thanks again for any help...

Solo

Solo, type the following into PuTTY:

Code:

ls -l /mnt/HD_a2/ffp/start/

You're looking for "-rwxr-xr-x" at the beginning of the editcron.sh line. If it's not there, then execute "chmod a+x /mnt/HD_a2/ffp/start/editcron.sh" at the putty # sign. To check to make sure you did it right, you can type the code above again and verify you get "-rwxr-xr-x" now.

FYI: any item that shows "-rw-r--r--" will not be executed at boot-time.

Another thing you can do is look in your fun_plug.log file, to see if there were errors when trying to execute the editcron.sh file

robertvk · 2008-06-25 01:15:06

I'm getting a 'permission denied" log, sorry to be such a noob, I'm not sure which permissions to look at...? Thanks so much for any help!

The log is: /mnt/HD_a2/ffp/bin: Permission denied.

But I can just run

/mnt/HD_a2/ffp/bin/rsync -av --delete /mnt/HD_a2 /mnt/HD_b2

as per shadow349's 12.5.08 post.... copying away happily now.

I have the same problem as previous poster. I'm using ffp 0.5 on a usb stick.
crontab -l gives the correct reply, but nothing happens at the specified backup time. (i did create a log directory in /ffp)
the manual command does the job without problems.

SpectralDesign · 2008-06-28 01:38:23

knireis,

that the line is in crontab is a good sign, but my first guess is that perhaps you haven't rebooted? If you reboot, and without doing anything other than logging in and a `crontab -l` you see the line in there, then everything *ought* to work as expected. (I think the reboot is required because the DNS-323 doesn't re-read crontab after booting (in other words, changed made after booting are ignored by the O.S.)

At least, that's my best guess at the moment....

Thanks for the reply but i did a reboot. I used to make a backup with funplug 0.4 and that worked fine, but since 0.5 i can't get it to work automatically.

knireis · 2008-06-28 10:09:37

As extra information: in the ffp.log file the following lines about the editcron:

* /ffp/start/editcron.sh ...
BusyBox v1.00-pre1 (2007.12.10-08:03+0000) multi-call binary

Usage: crontab crontab [-c dir] {file|-}|[-u|-l|-e|-d user]

Is this the normal situation?

knireis · 2008-06-29 11:35:18

I don't know why (probably some finger trouble earlier), but it started working last night.

TomSluyts · 2008-07-01 20:02:57

For a "normal" incremental backup, is this rsync command correct ?

/mnt/HD_a2/ffp/bin/rsync -a --update --delete /mnt/HD_a2 /mnt/HD_b2

This should : delete all files in destination that are not in source, overwrite any old files on destination and leave the == files alone, right?

greg · 2008-07-08 17:08:36

I apologize if these are stupid questions. I've been running this backup procedure for several months now with just 2 disks, backing up Volume_1 to Volume_2. 2 questions:

1. I assume the rsync is unidirectional, correct? So that if Volume_2 fails, it won't erase everything on Volume_1, right?

2. If Volume_1 fails, would I just move Volume_2 to the Right drive and restart?

Chumby · 2008-07-13 15:16:51

Howdy Greg,

Just moving Vol_2 over to Vol_1 wont work, because the backup drive (Vol_2) stores data in a unique folder.

Have you thought about introducing a third drive?

Cheers
Chumby

I'm open to adding a 3rd drive, but the question would still be the same: what happens if the Vol_1 drive fails? I would then have 2 backups. I'm just trying to work through the sequence of what to do in the event of failure (rather than trying to figure it out in the heat of the moment).

If I can't simply move the LHS drive to the RHS bay, then I would need to have a blank drive on hand to put into the LHS in the event of failure. Format that, and then copy back from Vol_2 to the new Vol_1?
