Backup takes forever

[Pagemakers]

My 3GS has started to take about 10 minutes to perform each backup. The 16GB phone is less than one third full.

It’s happened before and the cure was to delete all applications and re-install them all. Then the backup would only take a few seconds.

I’m loathed to do this again. Is there another fix?

There is at least one application that I know of that makes for long backup times. It's AppSniper. There is an option in its settings to clear the icon cache. If you do that before backing up, your times will be much shorter.

I'm guessing that you have an application installed that has a similar nasty way of backing up.

If you want to take the time to track it down, this would make the job a little faster. Delete half of your applications. Check backup times. If they are slow, your culprit is still on the iPhone. Times are slow, delete half of the remaining ones, and so on. If, after deleting the first half, the times are fast, delete the remaining applications and reinstall half of the group you first deleted. Check backup times.

Once you narrow your group containing the suspect down to a manageable few, install them one at a time until you find the one giving you the problem. This will be much faster than installing and uninstalling all of your applications one at a time.

Then only you can decide whether that application is important enough for your to hang on to it.

If you do this, I would be interested to know which application is causing your troubles. Others might be too.

You could try resetting warnings in iTunes:

Now my syncs have speed up 10 times over. I’ll let you know how it goes over the next few days.

The most annoying thing in my opinion, is that you don't need to back up your phone every time you sync. What I have found, is that immediately after you hit the sync button, you can press the "x" in the top display area to cancel the backup, but itunes still continues to sync the phone. I do this almost every time with no problem at all.

You need to do the corrupt app fix. I do it every so offen and backups take 10 seconds to a minute max.

What is the corrupt app fix?

I found this by searching the forum.

Indeed that does work but I really only want to do that as a last resort because you lose all of your installed app settings and data.
