I've been backing up my databases by piping pg_dump into gzip and burning the resulting files to a DVD-R. Unfortunately, FreeBSD has problems dealing with very large files (>1GB?) on DVD media. One of my compressed database backups is greater than 1GB; and the results of a gzipped pg_dumpall is approximately 3.5GB. The processes for creating the iso image and burning the image to DVD-R finish without any problems; but the resulting file is unreadable/unusable. My proposed solution is to modify my python script to: 1. use pg_dump to dump each database's tables individually, including both the database and table name in the file name; 3. use 'pg_dumpall -g' to dump the global information; and 4. burn the backup directories, files and a recovery script to DVD-R. The script will pipe pg_dump into gzip to compress the files. My questions are: 1. Will 'pg_dumpall -g' dump everything not dumped by pg_dump? Will I be missing anything? 2. Does anyone foresee any problems with the solution above? Thanks, Andrew Gould ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
