Syncany

Other questions

Asked by Ernesto on 2011-07-20

Hi guys
I'm sorry if I interrupt, but I have many questions again. Really, as I said, think that Syncany is a promising project, and I would like to try and help in whatever it takes.

My questions are as follows:

- In the content of ".syncany", Which stores exactly the subdirectory "db"? because his content are binaries files. Why is empty the subdirectory profiles?

- In the subdirectory cache, Are fragments of original files the trunks files?

- In the repository folder of each store type, in one of the PC are generated many files "profile-user" constantly instead of delete them as others PC (All pc's have the same syncany version)

- In this folder I guess when Syncany will finished all content will be encrypted

- Also I'd like suggest, if not already, that when implemented the recovery of file versions, syncany allows you to select how many copies stored

- To finish, I like know how synchronize Syncany with Dropbox

Thanks again for your answers

The subdirectory contains a derby database, which contains file versions/history and what file consists of what chunks. The profiles directory will contain the images of the users participating in a repo. I disabled this function because it was buggy.

> In the subdirectory cache, Are fragments of original files the trunks files?

Yes, those are fragments ("chunks") of the original files. The contents of this directory can be safely deleted when Syncany is not running. I will implement a cache cleaning mechanism at some point, so this happens automatically.

> In the repository folder of each store type, in one of the PC are generated many files "profile-user" constantly instead of delete them as others PC (All pc's have the same syncany version)

Syncany avoids lost updates [1] by simply never writing to the same file. New files are marked with a new timestamp in the filename. This happens with repository-, profile-, image- and update-files.

> In this folder I guess when Syncany will finished all content will be encrypted

Yes. chunks are already encrypted. Update-files are not yet, because it makes debugging easier.

> Also I'd like suggest, if not already, that when implemented the recovery of file versions, syncany allows you to select how many copies stored

That is of course planned :-D

> To finish, I like know how synchronize Syncany with Dropbox

I was working on a Dropbox plugin for Syncany. It doesn't work that good yet, so it's not released yet. However, keep in mind that because Syncany has a distinct repository structure (the files are all encrypted), you won't be able to browse the files in your Dropbox folder (or in the web interface). Syncany will just use Dropbox as storage.

Cheers. And thanks for your interest.
