Thank you, Erick!This is a useful tool, but we look for smth that could store 
backups in local S3 (like minio), not Amazon or else..If I correctly 
understand, Medusa can't do it.
Nevertheless, thank you for your response!

Backup cassandra and restore. Best practices

2021-04-06 Thread Alexander Nikolaev 
Hello everyone!We have a new Cassandra cluster, which exists of 5 nodes in 1 
DC. Now, I looking for a tool, which could help backup data to S3 or smth 
locally. Could you help me please with best practices for backing up and 
restoring? Is it enough to have local snapshots? In my opinion, the better way 
is copying snapshots to another server also, like S3. How are you implement it? 
Which tools do you use?Thanks for sharing your answers!
With Best RegardsAlexander N.

 Hi 
I am struggling to find way to set read_ahead_kb for Cassandra in our 
Kubernetes environment. Any way by which we can achieve this? My issue is that 
since PV is mounted in a container and it can have any name depending on 
partition number. Also wanted to know where it will be set, inside the 
container or on the host machine?

Yes, Minio is supported by Medusa through the S3 compatible backend.
I reckon we need to update the docs with a guide on setting up those
backends, but it's pretty much the same as ceph s3 rgw in configuring your
medusa.ini :
- use s3_compatible as storage backend
- set the host, port and region settings appropriately to connect to your
Minio install
- set the "secure" setting to false (libcloud doesn't support ssl on s3
compatible backends)

And you should be good to go.
We also have integration tests that use the Minio backend.

Cheers,

Alex

As I stated in my response, Medusa supports any S3-like storage that the
Apache Libcloud API can access. See the docs I linked. Cheers!

Medusa /Support for local storage, Google Cloud Storage (GCS) and AWS S3 
through //Apache Libcloud //. Can be 
extended to support other storage providers supported by Apache 
Libcloud,/ and Apache Libcloud supports minio 
. 
So in theory Medusa supports minio.
