I posted this question on Stack Overflow
<https://stackoverflow.com/questions/49216195/mvstore-online-back-up> but
never got a response. I just want to know if this is a reasonable way to
do an online backup of an MVStore file and whether I'm missing anything
important (please forgive my Java, as I am actually working in Clojure and
don't know Java well):
// db is an MVStore instance
FileStore fs = db.getFileStore();
FileOutputStream fos = java.io.FileOutputStream(pathToBackupFile);
FileChannel outChannel = fos.getChannel();
try {
db.commit();
db.setReuseSpace(false);
ByteBuffer bb = fs.readFully(0, fs.size());
outChannel.write(bb);
}
finally {
outChannel.close();
db.setReuseSpace(true);
}
I tried following the docs, but certain things are vague or confusing to
me, so I'm worried I may be doing something wrong. Does the code above
look okay?
