Hbase backup

ashneesharma88 — Fri, 29 Jul 2016 16:41:28 GMT

I have one query. Is there any command to take backup off all table at a time or I have to take a backup of table one by one. If yes then please elaborate,

Thanks in advance for help.

Hi @Ashnee Sharma, I don't think there is a simple command to backup all tables at a time. To backup the whole hbase cluster, you need to shutdown it first and use distcp tool to backup all hbase data on HDFS.

To backup single table, you could use Replication, CopyTable or Export. You can find the details here: http://hbase.apache.org/book.html#ops.backup

My suggestion is that you can write a small script to backup all the tables one by one in a live cluster.

@Ashnee:

You can also use snapshot for table backup:
