Hello,
I have a Jolla phone which runs linux. Unfortunately the speaker has stopped working which rather renders it useless as a phone so it has to go back to Finland for repair. Jolla have suggested I take a backup as they will reset it and wipe it. But their backup doesn't backup everything so can I copy everything off it perhaps from this machine?
I easily ssh into the phone as a user and then switch to 'devel-su' mode but I don't appear to be able to ssh into it as root.
I've tried to run scp from within the phone (using ssh) to a NAS drive but I can't make it connect. At this stage I'd rather not install loads of extra software on the phone just to do the backup so any ideas about copying everything off the phone before it goes back would be appreciated.

Physician heal thyself!
I found a micro SD card in my old Nokia N900 and stuffed that into the phone and have now successfully done an rsync of various directories from the phone to the sd card.

Problems surfaced here when the device, something with 16GB of memory, managed to fill a 16GB memory card.
I managed to find a mount.cifs rpm for the phone and installed that. I can now mount my NAS box on the phone but I'm running into more problems with that.
I'm using this command :- /sbin/mount.cifs //192.168.1.25/Linux_Share/Jolla_Backup/Full_Backup -o username=Xxxxxx,password=Xxxxxx,uid=nemo,gid=nemo,sec=ntlm /media/Linux_Share/
If I then look at the output of mount, I see this :- //192.168.1.25/Linux_Share/Jolla_Backup/Full_Backup on /media/Linux_Share type cifs (rw,relatime,sec=ntlm,unc=\192.168.1.25\Linux_Share,username=Xxxxxx,uid=100000,forceuid,gid=100000,forcegid,addr=192.168.1.25,unix,posixpaths,serverino,acl,rsize=61440,wsize=65536,actimeo=1)
I'm using this command to 'sync' the files :- rsync -arv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* /media/Linux_Share
But when it runs, I'm seeing lots of these errors :- rsync: chown "/media/Linux_Share/data/app/.me.scan.android.client-1.apk.bqi2SO" failed: Permission denied (13)
If I check the attributes of the files on the NAS, they're all shown with my userid and group but how can that be when the phone is issuing these commands and there is no user 'chris' on that?
Oh. I should mention that I first issued the command 'devel-su' to run everything as root.
I'm puzzled and would appreciate some help as there's little point in doing a backup if the backup is not worth anything due to wrong permissions.

On my android, I use ES File Explorer to mount a samba share on my server. Works a treat.
Cheers, Laurie.

So are you saying that it's the way I'm mounting the share that's the cause of the problem?
Although Jolla phones *can* run Android apps, I'm not sure that it would have access to the underlying file structure. But I'm far from sure on that point.

In the past I've tried to use an rsync backup command and I've failed to exclude the media I'm backing up onto, which results in a backup that never ends until it's consumed all the disk space, as it backs up everything, including the backup, and as it backs up the backup, the backup gets bigger, which gets backed up....
I'd be tempted to backing up to the SD card again, but create an archive or compressed archive instead on the sd card - this should avoid any file permission problems.
I'd be tempted to add /media/Linux_Share to the list of excluded directories, just to be 100% sure that it was excluded from the backup.
This gave me a clue: http://ubuntuforums.org/showthread.php?t=930041
If it's a Samba share, it may just be that you can't do a chown to the files. - You've set the mount's username in the mount command.
Again, I'd be temped to create an archive or compressed archive file on the share. The advantage is the file can be owned by any user, but maintain the real file permissions and ownership within the file.
1) the mount command specifies the mount's user name - this may have something to do with it. 2) Linux stores file ownership via the user number, not the actual name. Create a file on a system with user name sid user ID 1000. Access this file from another system where user ID 1000 is James, and the user owner name of the file will be James, not Sid.
I can vouch for the usefulness of ES FIle Explorer.
When I've had to backup phones before, I've done it like this. I've attached the phone to a computer using a USB cable. The computer then notices the phone and asks if I want to attach the storage device. I say yes, then create an archive from the mounted phone's drive. This has always worked for me.
Good luck Steve
