N.612 Backup files could not exceed 4Gb (technology limitation). The fix consists in archiving the backup as a tar.gz instead of a zip. As a consequence, installing iTop now requires TWO additional PHP modules: phar/zlib. The zip module remains mandatory because it is used in other places. The restore utility accepts both legacy zip files and brand new tar.gz files. DBBackup::CreateZip is deprecated in favor of DBBackup::CreateCompressedBackup. DBRestore::RestoreFromZip is deprecated in favor of DBRestore::RestoreFromCompressedFile (which autodetects the format for backward compatibility).
