Well, my installation is based on the official deb package. However, you cannot automatically upgrade from 2.2 to 2.3. I think this is because graylog might change things overtime and they don’t want to break things without administrator’s supervision.
So you need to download and dpkg -i to install it manually.
Some Linux users user Deja-Dup / Duplicity to backup their files. The tools work pretty well and very reliable.
However, in very rare occasions, Deja-Dup will keep asking you a password even you put the right one. To debug this, you can do
DEJA_DUP_DEBUG=1 deja-dup --backup
to see what’s going on, and grabbing those error messages to find the right solution.
Interestingly, one of those occasions is that you have files with size = 0 byte in your backup set. These zero-byte files cause GPG fails when it tries to test your backup set even with the right password.
To solve this, simple, delete those zero-byte files from the backup set. It is safe to do so anyway. :P
Vultr has recently upgrade all instances . While $5/month has been upgraded from 1 CPU / 768 MB / 15 GB to 1 CPU / 1 GB / 25 GB, Vultr also introduced the new smallest server instance – 1 CPU / 512 MB / 20 GB at $2.5/month.
So, I have choices: keep paying $5/month and get an upgraded instance for free, or migrate to the $2.5/month to cut cost in half.
I chose the latter.
Unfortunately, Vultr does not allow to downgrade the instance (because disks can only be enlarged). So, I needed to migrate the server. I created a snapshot from the existing 15 GB disk, and deployed an $2.5/month instance from the snapshot. It took me about 10 minutes to create the snapshot (free), and few more minutes to deploy new instance. Then, I updated DNS record.
Things went well. So, finally, I destroyed the $5/month instance.
The result ? You are seeing it right now. This web is running on single $2.5/month instance :D
