Xtrabackup 2.0.1 incremental backup don't drop table

Asked by Shay Fox on 2012-07-30

Hello,

When I am doing full backup + incremental backup and restore it on another host I get orphan tables like table1 in the below log.
When I take the full backup, table1 was exist, but after a while when I took the incremental backup table1 was deleted (was dropped between the full and incremental operations). when I resorted the full + incremental on another host table1 wasn't drop properly, I expect it will be dropped after I restored the incremental and will be identical to the source DB.

note: no crash happened during the full and incremental backups.

is it a bug?

120729 23:55:42 InnoDB: Warning: trying to init to the tablespace memory cache
InnoDB: a tablespace 23837543 of name './DBname/table1.ibd',
InnoDB: but a tablespace 23831965 of the same name
InnoDB: already exists in the tablespace memory cache!
InnoDB: We assume that InnoDB did a crash recovery, and you had
InnoDB: an .ibd file for which the table did not exist in the
InnoDB: InnoDB internal data dictionary in the ibdata files.
InnoDB: We assume that you later removed the .ibd and .frm files,
InnoDB: and are now trying to recreate the table. We now remove the
InnoDB: conflicting tablespace object from the memory cache and try
InnoDB: the init again.

Thanks,
Shay
