---------------------------------------
Summary: Update tech details of backup
Key: HBASE-28078
URL: https://issues.apache.org/jira/browse/HBASE-28078
Project: HBase
Issue Type: Task
Reporter: Dieter De Paepe
The [technical details|https://hbase.apache.org/book.html#br.technical.details]
of HBase backup mention that the backup works by copying WALs which are
converted to HFiles during the restore process.
However, the code seems to imply that WALs are already converted to HFiles
during the backup process. (See
IncrementalTableBackupClient#convertWALsToHFiles.) I suspect the docs still
describe the old behavior, which (I suspect) was changed in HBase-14141.
Knowing this also confirms that bulk-imported HFiles are also backed-up -
something I managed to test with experimentation, but wasn't explained in the
backup docs.
In short, this section in the docs requires an update.
