2011-11-06 iTunes iPad Backup

The media on this iPad cannot be backed up because there is not enough free space on this computer to hold all of the backed up files (31.30 GB required, 3.57 GB available). Would you like to continue to update this iPad?
Continuing will result in the loss of all media on this iPad.

I hate you! My external disk drive has 214.03 GB available. Now what?

I think what I’ll try is move all my existing backups from ~/Library/Application Support/MobileSync/Backup/ to my external drive and link the new location to the old location.

  1. it did not work – even though this is what other people suggest as well
  2. tried it with a symbolic link instead of the links Finder creates, but it didn’t work, either
  3. tried moving MobilSync to the external disk and symbolic linking it, but it didn’t work, either

iTunes keeps telling me that there’s not enough space. >{

Hours later… I’ve deleted ~/Library/Caches/* and ~/Downloads/* for both accounts on this machine and I have emptied the Trash many times… and finally—finally!—there is enough free space to start the upgrade including a media backup.

Curious, however, I wanted to know where stupid iTunes is saving the backup to. Well, theoretically lsof will “list open files”. Let’s see:

Pyrobombus:~ alex$ lsof|grep -i backup 
AppleMobi 895 alex  txt      REG       14,2    499200 11536761 /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/AppleMobileDeviceHelper.app/Contents/Resources/AppleMobileBackup
AppleMobi 895 alex    7w     REG       14,5   2097152  3720396 /Volumes/Extern/MobileSync/Backup/346b7073bd3e141e94284c421ed96dc724f88ff9/Snapshot/8277946022662205f468e8e329528bfa8b0c9fbf.upload

I noticed that you might have to call this repeatedly because at particular points in time the process might not be writing backup files.

Anyway. What does this tell me? iTunes checks the available disk space on the default drive where it thinks the backup will be created, even though I moved the directory to an external disk. sucks

Well, I was hoping this fixed the stupid problem, but not so:

An error occurred while backing up this iPad (-50). Would you like to continue to update this iPad?
Continuing will result in the loss of all contents on this iPad.

Now what? Retry? I wonder what that means, exactly: Loss of all in-app purchases? What if the app is no longer supported—are the in-app purchases that I am unable to download lost forever?

Another question poses itself: Do I need a backup as part of this upgrade process? When I sync the iPad before doing the upgrade, I see that it is doing a backup. When I check iTunes Preferences → Advanced → Devices → I see “Alex Schröder’s iPad – Today 11:20” (not quite what I expected but close enough). Perhaps I can just upgrade the iPad and then restore this backup?

Googling for this error leads me to a thread where a user is saying “I had my MobileSync folder symlinked…” This is exactly what I did to avoid the first error. Needless to say, this makes me very unhappy.

What I’ll try next is deleting the symlink without moving the backup data back to the main drive and upgrade. We’ll see about the various backups after the upgrade. Perhaps the 31.30 GB required are just a temporary thing. I sure hope so.

It worked! When I came back this morning I saw Syncing Photos to “Alex Schröder’s iPad (Step 6/6)—Copying photo 16600 of 19540” ok

I love Apple - until it doesn’t work…

My thoughts exactly! sigh I switched to Apple after having used various GNU/Linux distributions for years. I spent a lot of time tinkering with the system. Apple appeared to offer a fix to this problem, and it just works—most of the time. When it doesn’t work, though…

Sorry to hear you’re in iPad hell. I just brought on line a 2 TB external (2 TB … and I recall the days of tape) for my media. In my case, it was the prior drive going down, taking all the music with it (and nearly the MacBook, whose hd was also entirely full). Managed to recover an old episode of the podcast, plus (thanks to iCloud, I’ll admit) a ton of music.

Episode 60 was good! The amount of work producing a sound track for every player is staggering, however. Wow!!

2008-03-21 Send iTunes Tracks To SqueezeBox

Ok, I finally solved my problem! I mentioned it on 2007-12-02 iTunes vs. Squeezebox –– I like how iTunes lets me quickly collect the stuff I want. But then I can’t play it on my SqueezeBox. Suckage! I tried some suggestions from the Slim Devices forum [1] and I finally figured out what I wanted: I want to select some files and “send them to the Squeezebox” – I don’t want to play the same song in iTunes and on the Squeezebox, for example.

Brad Mohr’s script did exactly what I wanted it to do. Except that it assumed an old version of the server software, and it required me to change a little security setting, or it required me to figure out the “cauth” key. No good! Some looking at documentation that came with the new server, some looking at AppleScript examples elsewhere, some fiddling with netcat (nc), and soon I had something that seems to work.

Yes, netcat is the awesome! :)

Anyway, here it is. To use:

  1. Open the AppleScript editor → Applications → AppleScript → Script Editor.
  2. Paste the code below.
  3. Hit ⌘R to run it. Good for testing.

To install it, you have two options. Here’s how to have a stand-alone program:

  1. Save, pick “Program” as the format to use. I used “Send iTunes Tracks To Squeezebox” as the name.
  2. Select some tracks in iTunes.
  3. Run the program. It will ask you whether you want to “Play” or “Append”.

Or to have it available from the scripts menu in iTunes:

  1. Create the directory ~/Library/iTunes/Scripts
  2. Save, pick “Script” as the format to use. I used “Send To Squeezebox” as the name.
  3. Select the tracks in iTunes.
  4. From the iTunes Script menu, pick “Send To Squeezebox”. It will ask you whether you want to “Play” or “Append”.
  5. Unfortunately, that doesn’t always seem to work, and I haven’t figured out why. :( If you uncomment the display dialog result buttons {"Ok"} at the very end, you’ll see that when run from the Script Editor, everything works as expected, and when run from within iTunes, the result is the empty string. Always.

2007-12-21 Useless Checkbox

I use Mac OS 10.3.9 on my iBook; I have iTunes 7.5; I don’t have an iPhone and I don’t plan to get one. iTunes won’t let me uncheck the Ringtones folder. Grrrr! [1]

2006-07-03 Reorganizing my music folder

I’ve decided to reorganize my music folder. It was a mess of various stuff I had ripped at one time or another, usually when taking music to the office, using a variety of tools and depending on both CDDB and Freedb. Both sometimes have lousy meta data quality for a perfectionist. I want titles capitalized. I want the compilation flag set when possible. I want the genre to be correct according to my ecclectic taste. No, Trip-Hop is not “Alternative & Punk” and Raï is not “Ethnic” and Bachata is not “Latin”.

I’ve decided to stick to iTunes for the moment because that makes playing the music on my stereo in the living room really easy. I’m moving my files to a single external drive, which I will then backup to a second drive. No splitting of music library across systems and folders without a real backup plan.

So now I’m slowly moving one folder after another into iTunes, fixing meta data as I go.
