Backups Strategies Interrogations : I want your opinions

Hi Denis Robel

Just for your info…I tried for nearly two days to install onto a raid system with out any luck (4x 160 sas drives raid 0…2x2) for some reason every time i tried to recover disc space the install crashed…

I’ve seen something like that with “used” disks.
At the beginning of install, I hit Alt+F2 (or F3) to get to the shell and erased the partition table with dd if=/dev/zero of=/dev/sda count=10 (repeat for sdb).

Ok, thanks for that. it’s worth a try…I have some spare drives lying around I will give it another go this weekend, and see if I can load the stable 7.3 release on a test server.

@JOduMonT are you satisfied with such answers?

this is hard to define a backup strategy :slight_smile:

  • raid is not backup
  • internal/always connected disks are not backup (they can be stolen/flowed/burned with the server)
  • anything that requires human intervention to have a backup is the weakest ring of the whole chain…

backup is something that you configure and forget, but you have feedback (about failures) and try/test data restore…
backup is something not directly attached to the server (see above)… a nas in the same lan is far better
backup is something you can quite easily bring outside

Hallo Stefano,

indeed my backup is the external usb disc… I use two discs one is outside from the server location and one is used for backup and after every backup it will be rotated.
Once per month I’m checking the disk via smartmon tools and I make some restores to check the backups.
A Backup is never following the strategy fire and forget. You have always to check that you are able to restore your data.

Indeed, see my previous post
The procedure must be automated and with no human intervention need
The backup must be tested
The restore must be tested

So

If I consider this answer, and I consider it

Nethserver don’t trully offer a backup solution

because all of these choice are, more or less, always connected to the server and for sure, or more often than other, in the same building or worst in the same room.

I think it will be worth it to add a Destination like SSH or FTPS

Try the WebDav option that @dnutan added. It is available in the testing repository.

Read in that thread where to get a 1TB Webdav enabled storage for free. Based in the Netherlands, so you will not have NSA watching you. For servers in EU the connection is decent.

Hi,

Actually I’m studying to buy a VPS to try a NS instance and try to replicate my NS home instance to the VPS.
It coud be potentially an great feature in a backup plan.

It depend on want you think the NSA watching you
but Netherlands still in The Fourteen Eyes of Global Mass Surveillance

@JOduMonT what a well done page, thanks for posting.

Recently i was thinking to create a module about backup and rsync…for a remote backup it makes senses

Something like that could be nice https://splone.com/blog/2015/7/13/encrypted-backups-using-rsync-and-duplicity-with-gpg-and-ssh-on-linux-bsd/

It’s a bit offtopic, but if you encrypt your data yourself (IE: you have the key) then there is no way you can be forced to give your key in an investigation: you don’t have to cooperate with an investigation against yourself. So I don’t see why you think data isn’t safe in a .nl datacenter.

Another thing is that EU privacy laws go way further than US privacy (what privacy?) laws.

I don’t know, and don’t probably don’t want to know what is in your backup
But for my self, encryption is more if someones still my drive than being welling to be torturing for my data.

another 2c of the topic, which I love;

I hope you use Elliptic curve algorithm, or better you made your own algorithm
because if you use something like RSA, which sound close of NSA :slight_smile:
it’s was approved and spread by the NIST, which I’m pretty sure they share technique with the NSA

I don’t know if you have a clear plan in your head
but with online.net (scaleway) you could have a 2core for 3Euro per month

and it could be based in Netherlands if you want :wink:

I built Nethserver on their BareBone and Cloud version without any issue.
But just becarefull the barebone version have 2interface and the main one is direct on the net (no firewall) in front.

Or an Italy based VPS for EUR1,- per month with arubacloud.com (with less specs)

NethServer can do the firewall by itself… :smiley:

Works pretty well :slight_smile:
just created a 1€ (+VAT) VM using this code. Basically you will have a machine for free for one year :smiley:
Hint:
Just be sure you are using the “use voucher” link at the upper right to when you want to order a machine.
