Bug Description

When copying InnoDB files in stream mode, innobackupex does a special check that a file exists when tar4ibd has failed. If it doesn't, it just means the table was dropped while innobackupex was copying other files, so the error is ignored.

A similar check is required when non-InnoDB files are being copied, i.e. in backup_files(). Currently, it first takes a list of files for a database, and then iterates that list. So if a table is dropped during that process, it would fail with an error.

Funny. I just ran into this bug this last weekend and was about to patch it - Making some branches proposed to merge for a fix.

Basically just ignore error code 2 from tar (file not found) as non-fatal
