Hi michaeltk, We are aware of this bug and are doing our best to fix it. For now the recommendation would be not to change the case of symbols once you've created directory in the Sync folder. Thank you for reporting.

Hi tipoldo, There is a way to delete files on Android without synchronisation. Just share "read-only" secret to your Android device and when adding folder on Android - remove "Auto sync" option. In this case you can sync only files you need and upon file removal it will stay on the rest of peers.

Capi, according to official SQLite documentation db-wal files are temp files. Until everything is going fine with the database itself - they are safe to be deleted. Also, they are still deleted automatically when all connections to DB are closed. They could be useful when say your app crashes and db gets corrupt.

any log viewer. Notepad++ could do the job. But better pack it with zip (there is a lot of repeating info, so it should be packed well) and send to me for analysis. What about the logs from second peer?

Hi guys, Please share some information so we can fix the issue. 1. What is the amount of subfolders / files in your Sync folder? 2. What is the max. depths of directory subtree being synced? 3. What is your hardware? 4. Anyone can gather logs from both computers with full debug turned on (here goes instruction)?

Sync has a different concept than cloud storages. Cloud storage keeps your data on server and lets any of your devices / computers access to it and download locally. BTSync lets you synchronise your data between your computers / mobile devices without involving external storage server. Say, you want to keep your photo collection on your PC, your phone and your mom's PC. You add a photo folder on your PC, and couple of empty folders on mobile and on mom's PC. BTSync will shortly make all these 3 folders on 3 different devices equal. As soon as you add more photos - they will propagate to other devices as soon as they connect to internet. And vice versa, if your mom adds some photos to the "synced" folder - they will be copied to your mobile and PC as soon as you are available over internet. So, your storage will be limited with your device HDD / flash and the speed of sync - by the bandwidth of your connection to internet (or LAN if devices are in the same network). That's the concept, i'm also dropping couple of links below so you can find more information. Here is a simple explanation how to start with sync: http://www.bittorrent.com/sync/get-started Here are FAQs http://forum.bittorrent.com/topic/16410-bittorrent-sync-faq/ http://forum.bittorrent.com/topic/17782-bittorrent-sync-faq-unofficial/

Okay, if you are able to load this bandwidth with FTP/SFTP from the same host, it is definitely not an issue. Here goes other places I can think of: 1. BTSync behaves gently to the bandwidth, if you have some networking activity - BTSync will shrink it's traffic to not to interfere with other activities. 2. BTSync reads the disk while transferring data with the lowest priority to make sure it does not kill the performance on computer. This can be also a reason if you have some disk activity on the remote PC. This is something you can try to adjust in your settings on both computers (see advanced settings, disk_low_priority which you need to move to "false"). 3. BTSync uses UDP protocol for data transfer, but I doubt that this is a reason of utilising only 10% of your bandwidth. Also, we are going to change this in future allowing TCP for even faster data transfer.

Hi linuxyogi, One of devices with btsync is Linux Mint. What OS installed on your other device(s)? Can you make sure that the device(s) you are trying to sync to have enough permissions to write into the synced folder?

Hi pinitrius, It's a pity that log was removed, it is really important for us to take a look at such issues. Now on technical side of the issue. There is only one case when local BTSync decides to remove file or files: when it receives updated directory tree from remote peer - and this directory tree contained no files which should be deleted. I wonder how much peers do you have for your photo library? Does any of peers stores synced folder on removable drive or network share?

Hi, BTSync does it best to detect file renaming, but it is not always possible, especially when you just change the case of some symbols on file systems that are not case-sensitive. For Windows that would be the same name, and for Linux it is 2 different names. It is a known issue and I would advise avoid renamings with just changing symbols case. We are working to fix this issue.

Hi blozo, Indeed, there is an event in Android platform which asks Gallery to rescan all folders for a new media. By default it is caused by phone reboot or storage mount (like, inserting SD card). BTSync can't trigger this event as it will result in high power consumption on Android. You can either mount/unmount your SD or look for some application in Google Play which can trigger Gallery rescan on demand.

4 days are definitely enough. Looks like BTSync wants to sync some file and fails to do it by some reason. Can you provide logs from both machines for analysis? Here goes the instruction. Also, it would be safe to remove db-wal files when BTSync is down.

Hi Zenfool, When you start using btsync - where are other peers located? local network or behind your modem? How many of them? what is the maximum upload speed your peers has? I can guess that your peers are using Asymmetric line and their upload speed is pretty humble, which means they just don't have enough outgoing bandwidth to fully load your incoming channel.

Hi lolcat, There is no any limitations to amount of files. I can guess that BTSync stumbled upon some unreadable file / folder. To identify the root cause I'll need a logs with extended debugging, see thread starting post for details.T Thanks!

Hi abc123, Can you please check that the user running BTSync on your WinServer 2003 has enough permissions to write received files to the folder you choose? If it does, can you please provide me debugging logs for analysis from both locations? Here is the topic describing how to get them. Thanks!

Hi, Unfortunately Synology NAS DS410 has old GLIBC (2.3) and we do not have a btsync build for PowerPC with such old GLIBC. So, btsync is not supported for this particular NAS unless you find a way to update your GLIBC.

Hi, We would like to add BlackBerry support as well, but definitely not in a close future.

Gerard, I'll let you know results of dump analysis. What about the files in these folders? Is there any huge files or large amount of tiny files?

Hi Chris, Can you please check if your sync folder contains any non-accessible sub-folders for your current user (for example, on Windows drive - System Volume Information folder)? If yes - this could be the reason (it is a known issue for the latest available build, 1.2.82 and is fixed in future version). If you don't have any non-accessible folders, can you please provide me debug logs from both computers for analysis? Here is a topic which describes how to collect debug logs. Thanks, RomanZ.

db-wal files should be deleted automatically. I'll check with developers if it safe to delete db-wal when btsync is down, but you definitely shouldn't do it while it is up and running. As for the sync showing 9kb - give it several minutes and it should re-evaluate data volume necessary to sync. Current UI does not show which files are actually going to be synced, only those that are in process.

Hi AnthorNet, SQlite stores a write-ahead log in this file. It is growing rapidly most likely due to extensive file operations in Synced folders. We are working to optimise it's size in future. As for sync.log - it grows as you have extended logging turned on. To turn off logging go to .sync folder (located bar btsync binary) and find a file debug.txt. Delete it, your sync.log should not get growing (or growing extremely slowly).

Hi, No crucial information discovered. B can learn A's peer id, share id. BTSync does not send any secrets.

Hi sebforeb, There is a bug in Android version of BTSync which won't allow you to do it. Now if your folder set up for selective sync - folder/file deletion will delete it on other synced devices as well. By design for selective sync it should remove folder/file on device only with ability to re-sync it on demand if necessary. UPD. It is not a bug. Android supports full BTSync synchronisation, so deletion of a file EVEN in selective SYNC will result in file deletion on your other devices. If you want just to sync some files / folders selectively and do not remove them from other devices - just put a read-only secret on your Android.

Hi gerard, How many files / folders are set up to be synced on your dell tablet? Excessive number of files might bring this issue. Also, I would appreciate if you can create a dump for BitTorrent Sync process when UI hangs and share it to me for analysis. To create a dump on Win8 machine open a Task manager, right-click the process (or long-tap if this is tablet) and choose "Create dump file" in context menu. Task manager will let you know the location of freshly created dump file.

To transfer data thru relay server BTSync tries to contact r.usyncapp.com server with UDP over port 3000. Relay server identifies packet destination and redirects it to appropriate peer. Keeping in mind that school network is strictly fire walled and does not let anything out except destination port 80 - relays will definitely won't work. Also note, that using a relay server reduces the strong side of BTSync significantly - the speed of synchronisation. The only way in such configuration would be to use "known hosts" and try to use a single open port to establish connection to your office and try to track where packets are get lost. Hope it helps.
