Restore backup issue

[alexbarta]

Hi Maor,

I'm doing my tests with default cassandra docker image and latest minio.

kubectl run cassandra --labels='app=test' --restart=Never  --image-pull-policy=IfNotPresent  --image cassandra --env='CASSANDRA_CLUSTER_NAME=test'

Probably I'm doing something wrong.

Backup goes fine:

~ $ cain backup -n default -l app=test -k keyspace1 --dst s3://cassandra

In fact I can see the data in the bucket

But restore returns an unknown error:

~ $ cain restore --src "s3://cassandra/default/test/keyspace1" -n default -k keyspace1 -l app=test

[alexbarta]

Now working! It looks like that cain pretends cassandra to be a folder not a bucket..
I have also tried dropping the keyspace and deleting it from /var/lib/cassandra/data folder... cain didn't work. In such case do you have to create the schema manually before restoring?

Hey,

So the first attempt didn't work for you because cain couldn't get the schema.
I am able to reproduce this locally by dropping the keyspace and running restore.
I have added a validation for this part so that a clear error message will be displayed.

Assuming that there was a schema, the restore will still have failed, for two reasons:

1. You specified the --src including the keyspace - added a warning for this case
2. You didn't specify a tag - added validation for this case

Regarding backup and restore to an s3 path such as s3://cassandra - i have checked that and it works as expected.

If you have any other issues - don't hesitate to raise them!
Very glad you are involved ;)

[maorfr]

And btw, I have just added version 0.4.1 which allows to restore the schema as well! ;)

[alexbarta]

Great, thanks for adding the feature!! BTW I have a couple of questions, if you don't mind:

• does cain support also incremental backups?
• On a three node cluster (e.g. w/ replication factor 3 keyspace) do I have to run cain against each node and create three separate backups ?
• Does cain support restoring a pre-existing backup on a fresh cluster installation? (I know Cassandra has problems if the new cluster has different IPs from the previous one)

[maorfr]

Hey,

• cain doesn't supoort incremental backups. The infrastructure is in place, but the logic is complicated.
• cain backs up a cluster, doesn't matter how many nodes. It's important to note that number of replicas and replication factor are two different things.
• of course. As long as there is an existing schema and the specified tag matches that schema, or if there is no schema and the --schema flag is specified.

If you have more questions, feel free to ask :)

[alexbarta]

Clear! Thanks a lot
