Lost all my data ? Help please
-
Is someone now why this happen ?!! Is it can be related to the hosting provider Digitalocean ?
-
The host system of my installation is not running on digital ocean, as far as I know.
The provider is called linode??Sorry, but I'm not the one leasing the host or dealing with the provider at all
-
Same issue here on a DigitalOcean hosting. The database has first been wiped out while running v0.8.2, then again last night while running v0.9.0.

What's amazing is that happening to several people in the same days interval on different redis version and nodeBB version without touching anything from days !!!
I've backup up also every hour now !!!

Is someone here can explain me where to find if I have a backup.. How can I just lose all my data without a reason ?? Please someone explain me what's could have happened to my website ? I lose a nine months of hard work !!!
What's command I have to execute to try restoring my datas ?
-
@bitspook I don't want to throw out blind judgement here... Since I never used Digital Ocean. I've always used my own full scale dedicated. But does someone experience issue's with MongoDB and Digital Ocean? And like many people over NodeBB said, keep making backups.
Edit: I'm also wondering on what scale database wipes occur. They seem to be pretty rare. -
If you had Redis persisting to disk, it would be at
/var/lib/redis.It sounds like someone (or some script, rather) is going around trying to connect to port 6379, and if successful, flushing the database.
Better use AUTH and have good backups!!

@kacemlight This seems to be the case. I am able to connect to the redis server at nodejsworld.com:
$ redis-cli -h nodejsworld.com nodejsworld.com:6379> keys * 1) "sess:0d5qvchIPxvQ-lsGNTJkWL7s1SQBrd8v" 2) "ip:recent" 3) "schemaDate"Please take a look at this topic: http://redis.io/topics/security.
I realise this is a very rough time for you, @kacemlight, as you've lost your site data. I have every confidence that you will be more careful in the future and utilise backups in addition to setting up authentication for your database.

Well am I the only one a bit troubled about the fact that the default Redis security is so easy to avoid. I opened my Redis port from my router and connected to it without any single problem...

Did you take a backup of any sort?

That would not make any logical sense. DO is only your IaaS platform and does not touch the system itself. You would not suspect a hardware vendor in a physical deployment of deleting your database.

IIRC the default Redis config is "bind to 0.0.0.0", which means open to everyone. Might be the same with Mongo.
However, Ubuntu locks these configs down by binding to localhost only, so installing via
apt-getis usually better than installing by downloading and compiling on your own. -

That is expected. That means that the firewall is open on your OS (is the firewall running?) and Redis does this because it is designed to be in a cluster and would need the port open to talk to itself or to a Sentinel.
