well then the question is, when you change 1 byte in your files that are in an encrypted TrueCrypt container, does it change just 1 byte in the container data too, or much more due to the encryption?
-
yes they are on the same network (behind the same home router) and all are in the 192.168.1.100-255 range
still it goes over the internet though? could that be a bug?
-
anyone please?
-
hm i just read in one of the FAQ that sincarchive stores not only deleted files but older versions of modified as well.
it doesn't store modified ones with me? is that changed?
-
SyncArchive stores only deleted files right?
is there versioning, storing earlier versions of modified files? in cases of file corruption for example might be useful -
If transfer has been interrupted for some reason (internet down for example)
how we can force it to re-initiate and continue or we just have to wait? In that case how much?
-
i unchecked
- use relay server when required
- use tracker server
and left checked
- search lan
- use predefined hosts
that i did on both computers
i set each others internal network IPs and listening port under predefined hosts
and the transfer started just fine at almost 1MB/s
just to make sure it wasn't over the internet i disconnected the internet cable going to the router, leaving just the internal network working
well the second i did that the transfer stopped.
then the interrupted transfer didn't start again until i checked again
- use relay server when required
- use tracker server
and i can see that it's utilizing the VPN local area connection as well as the internal local area connection, so it is going over the internet (well over the VPN and back to be precise)
even if there is a vpn on one of the computers it still should be able to go without it and directly over the internal network, right?
-
From what i read and remember fixed size TC containers should be able to be partially synced
the one with non-fixed size were transfered all over again even you change few bytes.
Right?

GIven the settings it should be impossible it was going over the internet, unless it's a bug right?
-
do we have to add the predefined host and port on each of the syncing computers (each adds the ip and port of the other?)
-
bump to see if easier way has been found or it will be supported in the app
-
I guess I'll have to do that, at least until they add option for ranges in the predefined host and the listening port to be visible in the android install
-
ah that's way to complicated for me
i guess i can just start the transfer and disconnected the router from the internet and see if it continues to transfer?
-
My PC and phone are using Wifi from the same router. So i would like to sync with it locally.
I would like to add it's internal IP (192.168.1.*) to the predefined hosts on the PC.
Well i can easily obtain the listening port on the PC install of btsync, but there is no such option on the android app?
so.
1. How do we find the listening port of an anrdoid install
2. since the router often gives different IP to the phone everytime he connects to the router, is there a smart way around that. For example setting a range in the predefined hosts?
Basically the phone gets 192.1681.100-255
-
So I just check "Use predefined hosts" and add the internal IP of the second device? (192.168.1.something)
Even if one or both devices use vpn they still might find each other and transfer locally right?
I got them to have the arrows icons (which i suppose means peer to peer transfer) but the speed is about the same no matter if i add the IP or remove it to predefined hosts.
So I suppose it doesn't go locally.
1. How to check if it goes locally or over the internet.
2. do i put something for the port field in when adding predefined host.
3. the router gives different ip in the 192.168.1.100-255 range everytime a device connects, so is there a way to make it try a local range first and then go over the internet?
-
great point, thank you!

I think that syncing a TC volume would defeate one of TrueCrypts core security features. You know when you have to wait a long time when creating a new volume or encrypted partition in TC, it is filling that space with "random" data. This makes it hard to guess where data is located(if any at all) in the space. One of the ways BTSync deals with large files is to split up the file into chunks of 4MB to see if it needs to be updated if an attacker could watch the data from a TC volume being backed up to a service like backupsy they would be able to eliminate a large section of the volume and know exactly where the real data is located.
ok, but knowing where the data is, doesn't make the decryption any easier at all i believe?
-
no, but that's actually great idea!
p.s.
i know that with one computer being on vpn, it acts like they are on completely different networks, but even then, shouldn't be possible direct sync between those computers instead of relayed one?
(i understand that the cloud icon means that the sync is relayed?)
-
That's useful info.
So then I'll be looking for a way to set rules that it syncs only when on Wifi and Charging?
p.s.
did anyone tried micro sd bigger than 64GB in a phone?
-
bump for more input
-
One of the very few disadvantages of bt sync is that both computers should be on and online while syncing.
Well for most people, your phone is always on and always online, so why not use it for central server/cloud?
Seems like 64gb micro sd is the most, most modern phone support (if there are phones supporting more please do say) and in case that's enough for you, i don't see why not install bt sync on your phone as well and use it for "server".
It's just an idea i just got, so would like to discuss it and see if you guys see any major disadvantages to it?
My first thought is how this would affect the battery life?
-
There is a little cloud icon next to the device name when transferring, so i guess it means the connection is not direct but via relay?
However, it's turtle slow.
With newbie words, when it goes direct and when via relay?
How to make it go direct?
In this particular case, both computers are behind the same router but on VPNs.
Even if i disconnect the VPN of one of them it still goes via relay.
The corporate policy doesn't allow me to disable the VPN of the other one though.

Lets not get into the discussion of AES 128 vs. AES 256 again, both are secure enough.
The main point of this solution is that the files are encrypted on disk nad not only over the network.
Your point about shifted data is correct but I doubt TrueCrypt uses that a lot as it is a very uncommon operation that triggers worst-case behavior also in most of the filesystems.
I am currently using encfs and synchronize the encrypted directory over btsync. That works well and I did not find any problems so far.
I didn't mean that AES 128 isn't secure enough, but that leaving your encryption to 3rd party, especially in the era of PRISM is not considered serious solution for any at least half privacy concerned individual. Not implying anything about the BT guys in particular but just talking in general. (I love all their projects, keep up the great work!)
Also you can have them encrypted on the HDD but if you set a folder in the mounted container to be synced you will be syncing unencrypted files and relying only on the 3rd party solution encryption.
That's why I'm talking about syncing dismounted containers in particular and the tricks around them.

I'm sure a lot of people are using it for that already. Since VirtualBox images are known to just die after few moves I would appreciate if people with experience share their knowledge.
How do you go about syncing your virtual machines?
For example, do you sync the live image you use, or just copy it in a synced folder when needed?
Do you keep them in TrueCrypt containers for example, for the fixed file size and partial sync or just throw in the image files?
Does Sync manage to sync just the changed stuff of an image file or always re-transfers the whole thing?
