(1)Restore from data backup without --data option

Here restore is happening similar to restore from full backup but actually from data backup and that too without --data option. I am expecting that restore should fail and prompt an error message (or atleast a warning message) that --data option must be used with restore data backup.

Related one with --online option

Here expecting an error message that --online option can only provided along with --data option.

(2)Restore with --no-logs option from data backup 

{{{

Here restore should fail prompting an error message (or warning message at least) that --no-logs option can not be used with --data 

(3)Non-existent ds instance in --instance

{{{
[root@dhcp207-214 ~]# ipa-restore --data -p xxxxxxxx --instance=TESTRELM-TEST1 /var/lib/ipa/backup/ipa-full-2014-12-11-13-17-59/

No instances to restore to
[root@dhcp207-214 ~]#
}}}
Expecting error message : "Instance TESTRELM-TEST1 does not exist"

Similarly for --backend option

{{{
[root@dhcp207-214 ~]# ipa-restore --data -p xxxxxxxx --backend=userRoot1 /var/lib/ipa/backup/ipa-full-2014-12-11-13-17-59/

}}}

Expecting error message : "Backend userRoot1 does not exist"
