RE: AWS Cassandra backup/Restore tools

2017-09-12 Thread Durity, Sean R 
Datos IO has a backup/restore product for Cassandra that another team here has 
used successfully. It solves many of the problems inherent with sstable 
captures. Without something like it, restores are a nightmare with any volume 
of data. The downtime required and the loss of data since the snapshot are 
usually not worth it.

Subject: Re: AWS Cassandra backup/Restore tools

Hi,

here are the main techniques that I know of to perform backups for Cassandra :

  *   Tablesnap 
(https://github.com/JeremyGrosser/tablesnap<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_JeremyGrosser_tablesnap&d=DwMFaQ&c=MtgQEAMQGqekjTjiAhkudQ&r=aC_gxC6z_4f9GLlbWiKzHm1vucZTtVYWDDvyLkh8IaQ&m=hrZJx9SNtdlofcJElpjcjw4rp4rlAq8nZKSSsefCvCc&s=DMw6BkRjlkS9LM5RzcvTamwv8fj6_Czd4RcKBmJnUxc&e=>)
 : performs continuous backups on S3. Comes with tableslurp to restore backups 
(one table at a time only) and tablechop to delete outdated sstables from S3.
  *   incremental backup : activate it in the cassandra.yaml file and it will 
create snapshots for all newly flushed SSTables. It's up to you to move the 
snapshots off-node and delete them. I don't really like that technique since it 
creates a lot of small sstables that eventually contain a lot of outdated data. 
Upon restore you'll have to wait until compaction catches up on compacting all 
the history (which could take a while and use a lot of power). Your backups 
could also grow indefinitely with this technique since there's no compaction, 
so no purge. You'll have to build the restore script/procedure.
  *   scheduled snapshots : you perform full snapshots by yourself and move 
them off node. You'll have to build the restore script/procedure.
  *   EBS snapshots : probably the easiest way to perform backups if you are 
using M4/R4 instances on AWS.

Cheers,

If yes, did you run into issues using that tool to backup/restore data in PROD 
that caused any performance or any other impact to the cluster?

If no, what are other tools that people have used or recommended for backup and 
restore of Cassandra keyspaces?

Please advice.
