quickbackup-percona fails to detect xbstream format correctly

[shaneiseminger]

When attempting to restore an xbstream backup:

$ sudo quickbackup-percona restore /home/admin/2015-05-08_12-00-00-backup.xbs - Restore from /home/admin/2015-05-08_12-00-00-backup.xbs

ERROR - /home/admin/2015-05-08_12-00-00-backup.xbs appears to not be xbstream format.
Check that your quickbackup/stream setting is set to the type of file
you are trying to restore.


This definitely is an xbstream backup. The culprit is this line (line 321 in the version that came with my image):

[ `file ${RESTOREFILE} | awk '{ print $2 }'` != "data" ] && logerror "\nERROR - ${RESTOREFILE} appears to not be xbstream format.

When I comment it out the restore runs without issue.
