Using innobackupex 1.6 with an invocation of the form:
I get errors like:
ls: cannot access … : No such file or directory
Use of uninitialized value $inc_dir in scalar chomp at /usr/bin/innobackupex line 1657.
I tracked it down and innobackupex is shelling out to perl to list $INCREMENTAL_DIR which it does not need to do in this case. I believe the errors are harmless, but in the hopes that it might help someone else I’ve attached a patch that worked for me (caveat: not thoroughly tested, use at own risk. etc…)
