Sycing computers

[wightdiag]

Filled Dropbox with 6Gb of 'scope files, manuals and wiring diagrams, £150 for more space, dubious privacy, nagging emails, so looking for alternatives.

Found this syncthing.net/ it's great !

Keeps the Linux desktop, 2 Windows laptops synched up with the data I need, about to put it on the phone to just synch photos.. Works on your local network.

If only Autel would let me put it on the tablet I could sync the diag reports too!

Does this software provide the same shadow backup/version management of files as fully hosted services like dropbox and onedrive do?

Also, are there any protections in case a synced device suffers a ransomware attack or someone accidentally deletes a folder?

It certainly sounds like an interesting prospect, however I'm wary of using freeware/open source tools these days after our organisation got their fingers burnt when Truecrypt went under a few years ago.

I use Dropbox - to store things on the cloud and sync docs for work.

But... As I have a "tin foil hat" - I am carefull what I upload to the cloud.

Never would I back - whole drives up to the cloud.

So thus I use very little cloud space and thus my use of Dropbox is free.

Rule of thumb for backing things up you don't wanna loose - is back it up on three differing physical media!

The system I have just been working-on for the business (mostly the shop, but also the workshop files, and all the financial files) is as robust as I can make it, and it's totally independent of the cloud-providers and under my own control;

Two sites : 1) Home-office (base) and workshop on one network 2) Shop on its own network

Each site has a single Network Attached Storage, and each of those handles all the files, parallel to each other. So no single PC actually stores any of the working files, they are all on a Solid State Drive RAID array within each NAS.

Each NAS synchronizes in real-time with the other. So they are effectively a mirror of each other. They nominally synch over a Virtual Private Network, but that is not quite there yet - I use a cheat method of connecting them together via a Synology Quick Connect service, but as far as I can tell, with strong passwords, this is not too bad for security, but the VPN is the last bit to get right.

Also, each evening, each NAS has its own external backup drive (a little USB external SSD for each NAS), and that does a versioned backup every day, independently of anything else.

The theory is : Each site can run independently of the other, and no one PC can bring all the files down. Fire and flood are covered by having all the files on two sites. Ransomware attacks are dealt-with by having 30-day versioning that is more widely gapped as the files become older, but no back-up is more than 24hours old, and the backup time is picked to capture most of the important work within 6hours of it being put down onto the NAS drive. Each NAS drive has redundancy on the SSD drives within, allowing hot-swapping of new drives in-place of failed drives very quickly.

Oh, I forgot the final bit of the jigsaw - the whole NAS drive at home has a backup server that is an old PC running a RAID array of SSD's under Linux OpenMediaVault, but is left disconnected between backups. Each week, all the files on that server are synchronized manually, then the server switched-off and disconnected.

I use Quickfile.co.uk for book keeping which is all on line so they look after backups - There is the possibility of a regular download if you want it.

There is no cloud storage with this it just keeps your devices in synch, no reason why one of those devices could not be a virtual drive for back ups/cloud storage. You can make syncing one way. 

There are some technical advanced options to it that I have not looked into because I don't need to!

rhyds Just set up one way syncing, so only the desktop gets copies of the photos I take on my phone, deleting them from the desktop does not delete them from the phone.
