Please note it hangs all time on 99% - may be it is related somehow to
99% ?

apply-log hangs on partial backup
https://bugs.launchpad.net/bugs/342540
You received this bug notification because you are a member of Percona

Status in Open source backup tool for InnoDB and XtraDB: Confirmed

Bug description:
I did backup  as
./innobackupex-1.5.1 --include=art53.* ./  --stream=tar > /mnt/data/tmp/dat.tar  


I unpacked dat.tar 
and 
do
 ./innobackupex-1.5.1 --apply-log /mnt/data/tmp/dat/

there bunch of errors like:

090313 16:25:30  InnoDB: Error: table 'test/test_innodb'
InnoDB: in InnoDB data dictionary has tablespace id 1699,
InnoDB: but tablespace with that id or name does not exist. Have
InnoDB: you deleted or moved .ibd files?
InnoDB: This may also be a table created with CREATE TEMPORARY TABLE
InnoDB: whose .ibd and .frm files MySQL automatically removed, but the
InnoDB: table still exists in the InnoDB internal data dictionary.
InnoDB: Please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.0/en/innodb-troubleshooting.html
InnoDB: for how to resolve the issue.

InnoDB: Have you moved InnoDB .ibd files around without using the
InnoDB: commands DISCARD TABLESPACE and IMPORT TABLESPACE?
InnoDB: It is also possible that this is a temporary table #sql...,
InnoDB: and MySQL removed the .ibd file for this.
InnoDB: Please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.0/en/innodb-troubleshooting.html
InnoDB: for how to resolve the issue.

[notice (again)]
  If you use binary log and don't use any hack of group commit,
  the binary log position seems to be:
InnoDB: Last MySQL binlog file position 0 437810557, file name ./db02-bin.001225

090313 16:25:36  InnoDB: Starting shutdown...

InnoDB: Rolling back of trx id 4 9421214 completed
090313 16:25:36  InnoDB: Rollback of non-prepared transactions completed

but on last operation is seem hang (I waited few hours).

After Ctrl-C I got:

innobackupex: Error: 
innobackupex: ibbackup failed at ./innobackupex-1.5.1 line 427.
