P2P backup + storage

Question

Backup

Greetings. I request the hall's help on the issue of data storage.

Introductory :
1. There is a Linux machine - a home router, with a backup on board. Works almost 24x365.
2. There are three Windows computers, geographically distributed.
3. There is a mountain of files from different machines. About 700GB to back up. They replenish, move, etc. etc.

Current solution :
CrashPlan is used, from each machine to the server, plus in parallel to the CrashPlan cloud (from there the data was already available once, since there was no need to raise them from there and everything was synced back in a few days).

Dislikes :
1. Destinations that store backup data do not sync with each other.
2. (Consequence) The need to fill in two places from each machine. Although this is done by the autopilot, it is long and painful in the case of a cloud, while in the case of a home server, everything syncs up pretty quickly (due to the fact that many providers in Moscow feast with each other).
3. Sources are logically separated. I explain. Computer A has a bunch of photos that I want to edit on computer B. On computer 'B', I tell the CrashPlan client to "deploy me this folder from the backup from computer 'A' to my local drive." Then I correct these pictures and I would fill them back. BUT! If I want to put them there, I need to take them on a flash drive to computer “A” (because you can’t upload it over the network - it’s most likely not turned on), so that later I don’t sit with a sore head, remembering which pictures are on which I ruled the computer - I can’t upload it back from computer “B” - this will be a separate backup. That is, I want some kind of general volume.

What you want:
1. Something that will sync between several sources, and not just between a pair (preferably via p2p). This will speed up both backup and restore.
2. Cross-platform (Windows, linux)
3. Versioning (if I changed the file locally, I can restore the previous copy, if I deleted it, I can restore it).
4. Shared volume for files from different machines.

Yes, I fully admit that it can cost money (CrashPlan is also not free in my case). That is, in fact - I'm looking for software. If the authors have some kind of storage to sync there as well - well, if not - no problem - I rent somewhere a server on Atom with the required number of disks.

Any ideas? Thank you in advance.

Answer 1

a project from the authors of torrent technology, I forgot what it's called, for p2p synchronization between several of my PCs. here slipped about him a few announcements and articles.

Answer 2

maybe svn?

Answer 3

Only the previous version.

Answer 4

Who in btsync prevents you from putting a git repo and enjoying the distribution and versioning?

Answer 5

AeroFS, csync
