datastax enterprise - Is it possible to configure OpsCenter Backup Service differently per datacenter? -


dse 4.5.8, opscenter 5.1.3.

we running multi-region cluster, 6-nodes running in 1 dc, , 1 node running backup in remote dc. rf 3 in dc1, 1 in dc2.

after enabling opscenter backup service, single node in remote dc reaching high cpu every time backup running (running /bin/find of strange reasons).

the question why @ want backup backup dc (dc2)? possible configure backup service confine single datacenter?

a secondary question - 3 copies of data being backed in dc1?

thanks!

we running multi-region cluster, 6-nodes running in 1 dc, , 1 node running backup in remote dc. rf 3 in dc1, 1 in dc2.

because there 6 nodes in dc1 (rf3) , 1 node in dc2 (rf1), node in rf1 has 2x data each of nodes in dc1.

after enabling opscenter backup service, single node in remote dc reaching high cpu every time backup running (running /bin/find of strange reasons).

it make sense node (since has 2x data) has work 2x hard.

a secondary question - 3 copies of data being backed in dc1?

yes, backup service takes sstables each of nodes (all data in node including replicas) , backs them (either in local directory, or in s3).

the question why @ want backup backup dc (dc2)? possible configure backup service confine single datacenter?

no, can configure opscenter backups @ keyspace level not @ data center level. having sstables particular node enable bring node without having bootstrap if node lost.

furthermore, because backup service restore functionality uses sstable loader, can restore cluster new cluster different topology.

check out mani's blog post details on performance of backup service.
