I’m looking at Urbackup as an option for backing up a small studio, and we have a lot of raw captures and media that are very large and don’t change often, and I don’t want to have to transfer them over the network every time a full backup is ran.
Most of them reside on fileservers that have spare CPU cycles so calculating the hashes every time isn’t that much of a problem, but it seems there is only an option for client-side hashing under Internet options, any chance of it making it into the local network options? Otherwise is there any disadvantage to somehow forcing an “internet” connection over the LAN?
EDIT: It seems both the calculate hashes on client and connect to internet server even if local server available are missing from the Mac client, I’m assuming this is because it’s an early beta?
EDIT 2: It seems that the “Block differences - hashed” transfer mode also does what I need, but is there any way to enable it per client?
You can enable “Block differences - hashed” transfer mode per client on the server in the advanced tab (after checking use separate settings for this client).
Awesome, thanks! I guess I should download/install it in a VM and start trying it out.
How stable are the beta versions? Where (approximately, obviously I know nothing is guaranteed) would you say they fall on a scale of “production ready” to “don’t even think about installing this on anything you care about”?
I’m currently using server 2.0.21 on debian 8.3 and it is stable for what I’m doing so far (internet file & image backups). I’m planning on upgrading to 2.0.22 soon, but I would say it’s more or less production ready at this point.
I was looking this request cause I would like hash on client side in lan, but what i see on my server (2.1.20) for specific client (2.1.17) is “Local full file backup transfer mode” : Raw or hashed, do I misunderstand something ?
I have the same question: Full backup over internet is using hashes - only changed file are transferred actually. That works.
But currently (2.4.11) local fulls are ALWAYS transferring EVERYTHING. And I dont see any option which would change that in the advanced tab. I dont want to force the clients to internet mode really.
Is local full transfer mode hard coded? The posts above indicate, that it should be possible to change it? Am I not seeing it?
As I write - there is a translation error for Local full file backup transfer mode to german. German text states “Abbild” (image). But the string should be “Dateisicherung” (file backup).
@uroniI edited it at TransiFex! Please note that for the next update
But that option is set to “Hashed”. Why does urbackup transfer the files anyway?
