HBase backups
-------------
Key: HBASE-4618
URL: https://issues.apache.org/jira/browse/HBASE-4618
Project: HBase
Issue Type: Umbrella
Components: documentation, regionserver
Reporter: Karthik Ranganathan
Assignee: Karthik Ranganathan
We have been working on the ability to do backups in HBase with different
levels of protection. This is an umbrella task for all the backup related
changes.
Roughly here are a few flavors of backups giving increasing levels of
guarentees:
1. Per cf backups
2. Multi-cf backups with row atomicity preserved
3. Multi-cf backups with row atomicity and point in time recovery.
On the perf dimension, here is a list of improvements:
1. Copy the files - regular hadoop "cp"
2. Use fast copy - copy blocks and stitch them together, saves top of rack
bandwidth
3. Use fast copy with hard links - no file copy, it does only ext3 level
linking.
