Hi guys, More and more data in our company is moving from mysql tables to hbase and more and more worried I am about the "no backups" situation with that data. I've started looking for possible solutions to backup the data and found two major options: 1) distcp of /hbase directory somewhere 2) HBASE-1684
So, I have a few questions for hbase "users": 1) How do you backup your small (up to a hundred gb) tables? 2) How do you backup your huge (terabytes in size) tables? And a question for hbase developers: what kind of problems could cause a distcp from a non-locked hbase table (there is no way to lock table writes while backing it up AFAIU)? I understand I could lose writes made after I begin the backup, but if my distcp takes an hour to complete, I imagine lots of things will happen on the filesystem during this period of time. Will hbase be able to recover from this kind of mess? Thanks a lot for your comments. -- Alexey Kovyrin http://kovyrin.net/
