Making Time Machine work with the ReadyNAS

I'm not a mac guru so someone else may provide better advice.
you probably aren't granting the proper write permissions.

from a terminal window if you go to

cd /var
and type
ls -ltr

look at the permissions for db

mine is:
drwxr-xr-x@ 42 root wheel 1428 Dec 18 18:53 db/

if the same you may need to open up the permissions. If you need help with that ask.

fyi if you then go cd db
ls -a .T*

you can see the Time machine files.
-rwx------ 1 root wheel 16 May 1 2008 .TimeMachine.Cookie*
-rw-r--r-- 1 root wheel 1099 Dec 18 18:53 .TimeMachine.Results.plist

no clue if this will help but if you show your permissions that would help towards figuring it out.

On my machine, i read :

drwxr-xr-x@ 41 root      wheel     1394 18 déc 12:01 db

and

rwx------  1 root  wheel   16 19 fév  2008 .TimeMachine.Cookie
-rw-r--r--  1 root  wheel    0  8 nov 01:38 .TimeMachine.NeedsFullScan
-rw-r--r--  1 root  wheel  230 18 déc 12:01 .TimeMachine.Results.plist

taking a stab here but try chmod 777 .TimeMachine.Cookie from the db directory

if it says permission denied then do sudo chmod 777 .TimeMachine.Cookie

I just tried a sudo chmod 777 chmod: .TimeMachine.Cookie

The answer was : chmod: .TimeMachine.Cookie: Operation not permitted

arrrghh !

Try typing:

sudo chmod 777 etc etc

you'll be prompted for the admin password

I had this answer after having typed the admin password

cd on the mac to /var/db

sudo rm .TimeMachine.*

then return to TM perefences and you should be able to set this up.

Also to remove a previous setup I removed /Library/Prefernces/com.apple.TimeMachine.plist This did not fix the fail to create /var/db/.TimeMachine.Cookie but removing the orignal cookie files did...

OK, I did it... but i faced a new error !

The backup disk image could not be created.

arrrghhh !

I just did another try using my brand-new MacBook and I got the same problem :

- I follow the trick given on ReadyNas page,
- I can access the volume in the TimeMachine Control Panel,
- TM asks for a password to connect to the Nas. I enter the admin password of my ReadyNas
- TImeMachine starts

- but I got the following error :

The backup disk image could not be created

Even when using the command :

defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

The error continues ! !

Well, my ReadyNAS is configured very simply :
- Security mode : Share (I have no groups or users configured on the Nas)
- The volume I created for TimeMachine is accessible in R/W via all protocols

I do not understand where the problem can be... :evil: :evil: :evil:

Your description of what you did makes it sound as if you left out the non-trivial steps: Creating the sparesimage file on a local disk and copying it to the NAS. It's not possible to create a sparseimage file on a remote disk. (Well, in principle it's possible, but hdiutil, the command line utility that Disk Utility - and almost certainly Time Machine - use to do that refuses to.) Once the sparseimage file has been created, it can be accessed remotely - which is way creating it on the local disk and them copying it works.

If you did create the file and copied it, make sure you got the name exactly right or Time Machine won't find it (and will probably try, and fail, to create an appropriate file).
