We have also made backup and restore for Apache Cassandra,backup process
are
1.do incremental backup for flushed sstable ;do incremental backup for
commitlog ;
2.do snapshot for the cluster periodically,also meta info are needed to
backup(token and table info);
3.for exception like node joining
Hi Krish,
It is recommended to have backups. Although I haven't practiced it myself,
but I find this might be helpful.

Hi Folks,
First question is , Do you take backup for your cassandra cluster ?
If answer is yes then question follows:
1. How do you take backup ?
1.1 ) Is it only snapshot?
1.2 ) We are on AWS with very large cluster around 51 nodes
with 1TB data on each node.
Repair during upgrade have caused corruption too.
Also, dropping and adding columns with same name but different type

Is compression enabled?
If not, bit flips on disk can corrupt data files and reads + repair may send
that corruption to other hosts in the cluster

Few for reasons:
Sudden Power cut
Disk full
Issue in casandra version like Cassandra-13752

Hi,
I'm trying to do a point in time restore using commit logs.
It seems to be working fine if I have primary as text but it does not work
and just restores all the rows if the primary key is blob (which is default
if I create a keyspace using cassandra-stress).
Is this a known issue?
Thanks

Hi All,
I am currently experiencing multiple datafile corruptions across most nodes
in my cluster, there seems to be no pattern to the corruption. I'm
starting to think it might be a bug, we're using Cassandra 2.2.13.
Without going into detail about the issue I just want to confirm something.
