Restore snapshot without losing connection with bitnami

servidigital 2016-05-07 02:24:04 UTC #1

I can create "catch" in google (snapshot) using them as "backup" and restore them on the same server, liaising with Bitnami?

I ask this because I'm testing, and to create a snapshot on a disk B dedicated to backups; I can not restore that capture the same instance, however the system tells me I should create a different one.

I hope you can understand

Note: I'm using wordpress bitnami with google cloud in a virtual machine.

Hi @servidigital,

To restore a snapshot of a Server you'll need to create a new server using a backup previously created. You'll learn how to work with the backups following these guides:

https://docs.bitnami.com/google/faq/#Howtobackupaserver?
https://docs.bitnami.com/google/faq/#Howtorestoreabackupofaserver?

Let us know if they work for you.

ok, but if I restore that way, a new instacia is created.

I can just Reboot the server, using SSH access data and use the settings from https://google.bitnami.com/?

Hi @servidigital,

It is not possible to restore a snapshot, which will create a new instance. It is not possible to restore a snapshot without creating a new instance.

To avoid loosing connection with your web page, what many developers do is to have both instances (the original one and the newly restored one) running at the same time. One of them (the original) will have the domain pointing to it, the other one will not be used yet. This way, you only need to change the DNS to point to the new instance.
Note that by doing this, you should have your database stored in another instance or engine, like RDS.

Let us know if you have any question about this.

Best regards,
Marcos

Hi all,

Backup and restore with snapshot is good but the new instance will have a new IP from the original one. So I need to to change DNS to point to the new IP? Will it take time to propagation? Thanks.

Hi @tradecross,

Yes, if you modify the DNS configuration it could take some time to be fully propagated. You can use this page in order to check the DNS propagation

Another way to perform this change is to configure your new server with your domain name:

https://docs.bitnami.com/?page=apps&name=wordpress&section=updating-the-ip-address-or-hostname
https://docs.bitnami.com/?page=apps&name=wordpress&section=how-to-change-the-wordpress-domain-name

and then stop the old machine and assign the static IP to the new server.

Let us know if you have any doubts about any of those solutions.
