Ios Backup Very Slow

[chosenken]

I'm trying to re-backup my iPhone using BitTorrent Sync.  Installed is 1.3.41 on 7.0.6 (iPhone 5).  Yes, it is jailbroken.  Running 1.3.106 on Windows 8.1 pro x64.  The upload speed from the phone will jump up to 4 - 5 MB upon starting the app.  However after about 2 min the upload speed falls to 2 kB/s and stays there.  Need to back up about 7.5 GB of Photos/Vids.  Any idea why it is slow now?

Could you please take a look at your desktop and check 2 things:

1. What traffic desktop shows? Are files actually appear on the desktop?

2. How your iPhone looks like on the "Devices" tab? Is there a cloud icon indicating that connection went thru the relay server?

Because I was experiencing the same issue let me answer some of those:

 

1) Yes, files show up on the desktop. Very slowly.

2) No cloud icons, just the two arrows that (I assume) denote a direct connection

 

In my case sync used to work fine. I'd get around 2MB/sec transfer rate normally. Then one day it just dropped to ~1KB. No apparent reason, nothing changed that I know of.

 

Also in my case both the phone and the desktop are on the same local network.

 

Things I tried:

- Restarting BT Sync

- Killing BT Sync on the phone and restarting it

- Rebooting phone

- Removing the folder from BT Sync desktop, and creating a new one (new folder, same secret)

- Rebooting desktop

 

What finally worked:

- Deleting BT Sync from my phone and re-installing it

 

This ended up creating a new secret as well. I'm wondering if I had just created a new secret instead of re-installing if that would have fixed it. If it happens again I'll try that, or perhaps someone else this is happening to wants to try it.

Quick add-on to that. Before I noticed that the bandwidth had dropped dramatically, I noticed it wasn't syncing some files. Normally it's very reliable (let it backup, everything appears on my desktop). This time everything appeared except for a few images which refused to appear on my desktop no matter how many times the backup claimed it was complete. Might be completely unrelated, or maybe not.

Yes. Instead of reinstalling the whole app, next time just restart backup: disable it in BitTorrent Sync settings and enable again. This will force reindexing of Camera Roll and you will need to share new secret  with your PC.

Are there any 'edited' photos in your Camera Roll? I mean edited with standard tools (filters, cropping, rotation, etc). These will not sync.

You mean the edits won't sync, but the original image does? Yes I've seen that happen, where I sync, then crop, then sync again but the cropped image does not show up on the desktop (the original image remains). BT Sync backs up each image once I believe.

 

That's fine, but that wasn't what I was seeing. There were new photos taken with the camera app that hadn't been touched that were not syncing.

ravisorg,

That is what I meant. only original files will be uploaded, not edited.

Do you have auto backup enabled? Check it in Sync settings -> Camera backup.

ravisorg,

Yes, auto backup is what I'm referring to in this thread. I've never used the manual sync method (to transfer individual files) on my iPhone.

Ok, I've found the issue for one of the problems - the random images not backing up. It's the same "conflicting filename" bug (#8085) I reported back in February. Basically I've taken enough photos (again) that the numbers have cycled around, and BT Sync will only backup each filename once.

 

For example on my phone at the moment:

 

IMG_8710.JPG was taken in Aug 2013

IMG_8712.JPG was taken in Aug 2013

IMG_8713.JPG was taken in Aug 2013

 

I also have newer photos that have the same filenames:

 

IMG_8710.JPG was taken in Aug 2014

IMG_8711.JPG was taken in Aug 2014

IMG_8712.JPG was taken in Aug 2014

IMG_8713.JPG was taken in Aug 2014

 

BT Sync sees those as the same filenames and won't back them up. So on my desktop I have:

 

IMG_8710.JPG was taken in Aug 2013

IMG_8711.JPG was taken in Aug 2014

IMG_8712.JPG was taken in Aug 2013

IMG_8713.JPG was taken in Aug 2013

 

...and the other 3 files from Aug 2014 refuse to backup.

 

The fix for this is to delete all the old images (in my case, from Aug 2013) from my phone, clear out the sync folder on my desktop, and re-run sync.

 

Long term BT Sync needs a way to handle different files with the same name, at least for iOS backups, because this probably happens a lot and people aren't noticing it (and thus losing images).

 

So that's one mystery solved. We still don't know why backups sometimes suddenly become very very slow though.
