Jesse Yates commented on HBASE-5547:
------------------------------------
@Ted: you would still need to check the directory quite frequently or everytime
you archive, you do some extra work adding the size of the files, both of which
are unpalatable. You can get around this though by just cranking down the time
between checks and then use a HFileArchiveSizeCleaner (or something like that).
I can see that being useful - file an issue?

> This came up in a discussion I had with Stack.
> It would be nice if HBase could be notified that a backup is in progress (via
> a znode for example) and in that case either:
> 1. rename HFiles to be delete to <file>.bck
> 2. rename the HFiles into a special directory
> 3. rename them to a general trash directory (which would not need to be tied
> to backup mode).
> That way it should be able to get a consistent backup based on HFiles (HDFS
> snapshots or hard links would be better options here, but we do not have
> those).
> #1 makes cleanup a bit harder.
