It isn't safe to backup the file that way. You need to use the inbuilt
backup command if the database is in use.

I don't know what's causing it. We have a feature that backs up the H2
DB file and zips it via java. the DB is in use when we back it up (all
it does is copy the h2 file) When we tried to use it, it's corrupted.
This is the stack trace when I try to open it
ZipOutputStream append = new ZipOutputStream(new
FileOutputStream(fileFullPath));
java version "1.7.0_55" on mac and file size is 1.4 MBs and we have a
lot of / (slashes) stored. I am not sure where to begin to find it. Is
it H2 ? is it our code writing/copying the file? (tests can't
reproduce it) What is this error ?
