Start a database backup
#include <qdb/qdb.h> int qdb_backup( qdb_hdt_t *db, int scope );
qdb
This function performs a backup on the connected database db and optionally any attached databases, depending on the scope argument. Backups are controlled in the configuration object, with the BackupDir and Compression options. For more information about these options, see the Database configuration objects section.
A client can cancel a backup operation by calling qdb_bkcancel(). If a backup is canceled (either by a client or through the QDB resource manager interface), the call to qdb_backup() fails and returns -1, with errno set to EINTR.
