Creates online backup of given database. The functions assumes 500 steps and a sleep time of 250 msec by default, if the arguments are not passed.

The function returns the following error codes:

  • E_DB if closing the database failed.
  • E_DB_BACKUP if SQLite backup failed.
  • E_EXIST if backup database exists.
  • E_READ_ONLY if database is opened read-only.

Arguments
