Legato backups of ECC files

I was just informed that Legato backups of our ECC infrastructure server are not completing successfully because the backup encounters open files. All of the files that Legato finds open are in one of the three following directories.

E:\Program Files\EMC\SYMAPI\ldb\storapid_db\
E:\Program Files\EMC\SYMAPI\ldb\storevntd\
E:\Program Files\EMC\SMC\litewave\webapps\sem\WEB-INF\data\

The three choices I have are 1) exclude the files from the Legato backup; 2) purchase an Open File Manager module for Legato; or 3) stop ECC while the backup runs.

Of course I'm not going to stop ECC nor am I inclined to purchase an Open File Manager module. This leads me to the question, do I need the files in these directories if I ever have a need to restore the ECC infrastructure server, or if the server hard drive were to crash would I just reload ECC and then restore the repository?

Thanks.
