Best Practice - Rsync between 2 nas4free servers

[Lee Sharp]

This is nor rocket science... Or at least it should not be...

I have two nas4free servers, and I want to use rsync to keep them in sync. But when I try, things get ugly fast...

GUI - (Or "Why, why, why, dear God why?") - So, I have to set up the server as Guest only? Well that will make backing up a bunch of files hard. I guess I could 755 my whole server. I mean what good is file security anyway? Oh, and encryption is overrated.

Cron - Well, this is no surprise, as all rsync GUIs in nas implementations stink. And I like cron... And you have a nice persistent cron in the web GUI. But... Where do I put my authorized_keys when /root is rebuilt on each boot?

I am sure someone has done this and not all rsync implimentations are between nas4free and real servers... But damned if I can figure out how!

Hello

I have another solution for you : zrep
Here the post
viewtopic.php?f=70&t=8166

You will have synchronization between 2 nas. It works very well for me.

But you need zfs, and I don t know if you using it

I looked at zrep, and it is an interesting thing... But I do not want continuous replications and i specifically do not want snapshots touched. So it looks like zrep is the wrong tool for the job.

But back to the topic, it just seems wrong to me that there is no way to rsync as root between nas4free boxes in a reliable way... Is this really the case?

I am using an offsite storage solution for my rsync with an Ubuntu box, but not for all my files. Just my tier1 files.(high value, about 120GB) but it helps a lot that I have 200/20 internet. I didnt use the built-in tools, since I wanted to ensure I have ssh keys in place manually. For 10 bucks a month I use ramnode ATL node, on their 200GB cached SSD hosting which is very very very fast. http://goo.gl/P8dC5L I also setup a cron to run it. This way if the house burns, Im covered.

Rsync remote for the initial sync can be a big issue if you have like DSL. Deltas are fast and cheap however.

I have done this often, and it is easy. However, this is between two nas4free servers in the same data center. While I can dump the command in cron, I can not keep my shared keys and have them survive reboot. Perhaps I need to post this in general and ask for a persistent root folder?

Are you using the full build?

Are you using the full build?

No. Nor do I really want to. There are good reasons for keeping data and system separate.

Id guess thats the restart issue then, and its not getting restored on reboots?

[Lee Sharp]

The GUI only allows you to access as guest, so you can not back up anything that is not world readable. And you can not just rsync in cron since it relies on ssh keys, which are stored in your home folder, which for the root user is /root, which is not persistant on reboot.
