Description Yedidyah Bar David 2015-04-19 13:37:18 UTC

Description of problem:

With bug 1188132, engine-backup supports the following new options:

 --archive-compressor=COMPRESSOR
    Use COMPRESSOR to compress the backup file, can be one of:
    gzip
    bzip2
    xz
    None
 --files-compressor=COMPRESSOR      for the files, same options as --archive-compressor
 --db-compressor=COMPRESSOR         for the Engine, same options as --archive-compressor
 --db-dump-format=FORMAT
    Engine DB dump format, see pg_dump(1) for details. Can be one of:
    plain
    custom
 --db-restore-jobs=JOBS             Number of restore jobs for the Engine DB, when
                                    using custom dump format and compressor None.
                                    Passed to pg_restore -j. Defaults to 2.
 --dwh-db-compressor=COMPRESSOR     for DWH, same options as --archive-compressor
 --dwh-db-dump-format=FORMAT        for DWH, same options as --db-dump-format
 --dwh-db-restore-jobs=JOBS         for DWH, same as --db-restore-jobs
 --reports-db-compressor=COMPRESSOR for Reports, same options as --archive-compressor
 --reports-db-dump-format=FORMAT    for Reports, same options as --db-dump-format
 --reports-db-restore-jobs=JOBS     for Reports, same as --db-restore-jobs

engine-backup should be tested on a large setup with various relevant combinations
of these options, in order to have data about their affect on the size of the
resulting backup file and the speed of backup and restore.

Was this done? Can we get the results?

Did we indeed choose well the details for:

--smallest

--fast-backup

--fast-restore

?

If not, what should be used?

Any requirements on where to run this tests?
Memory, processor, etc?

I'd say use the recommended specs - 16GB RAM, 4 cores.

Use a large db - of at least, say, a few tens of hosts and a few hundred VMs.

With DWH/Reports.
