I think you're right that database performance is the culprit here -- the database is postgresql running on the backup server. It's a RAID-10 volume on six SATA 7200RPM drives. The database itself lives on a different OS partition on the same volume as the spools. 2GB RAM and a dual-core Xeon 5110 aren't helping. An untuned postgresql has some potential for improvement without hardware changes, at least. >> Does anybody else have experience backing up tons of >> files? > > There are users that backup 30 TB containing millions of files in one > job on this list. So 50M files is not out of the ordinary? Thanks.
