Hi, I am thinking to implement regular snapshots on HBase to protect against user mistakes, e.g. if something bad happens go back to the previous snapshot. I am thinking to keep something as one snapshot per week for four weeks, and one snapshot a day for 7 days, so always have about 11 snapshots. Then each time a new snapshot is created, an old one would be deleted.
>From reading the doc I get the impression that snapshots are quite light to take, and have zero on-going performance impact, i.e. HBase will be just as fast with 11 snapshots than with none. Is that right? Am I also right to believe that the extra disk usage be very low in our setup where we never deleted any data, just add more? Finally, is anyone aware of a tool / helper script to implement such a snapshot strategy, before I spend time writing my own? Thank you, Thibault. -- View this message in context: http://apache-hbase.679495.n3.nabble.com/Snapshot-performance-and-helper-script-tp4080073.html Sent from the HBase User mailing list archive at Nabble.com.
