[opensuse] /var/adm/backup/rpmdb
The cron script cron.daily makes daily copies of the database (packed with gzip) and stores them in /var/adm/backup/rpmdb. The number of copies is controlled by the variable MAX_RPMDB_BACKUPS (default: 5) in /etc/sysconfig/backup. The size of a single backup is approximately 1 MB for 1 GB in /usr. 1-Why 5? 2-What do I loose if if I keep 1 or 2 instead of 5? 3-What do they offer that rpm --rebuilddb doesn't? 4-Why isn't rebuilddb in the rpm manual? 5-Why 30,000k per backup file? (My /usr is typically <3G total, including /usr/local/ which is on a separate filesystem.)

1-Why 5?
Why not? You have to pick up some number by default.
2-What do I loose if if I keep 1 or 2 instead of 5?
You have less time to realize something went wrong. Although with btrfs with enabled snapshots you have database backup as part of snapshot anyway, and exactly at the right time - immediately before it gets changed - so usefulness of this periodical job is questionable.
3-What do they offer that rpm --rebuilddb doesn't?
rpm --rebuilddb recreates other files from Packages. You still need consistent Packages to start with.
4-Why isn't rebuilddb in the rpm manual?
Because nobody took time to submit a patch?
5-Why 30,000k per backup file?
Because this is the size to which Packages gets compressed. If you want to know why it gets compressed to this size you probably need to ask on gzip list. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It doesn't depend on the /usr size, but on the number of packages. Maybe on the number of files, if the database stores a list of files per package, dunno.
1-Why 5?
Nice number
2-What do I loose if if I keep 1 or 2 instead of 5?
Sometimes 5 is not enough. I have it set to 10, because I found out that 5 was not enough. If you are unlucky enough to *need* this backup, and you find this out a week after the breakage, you are doomed, but I am not :-P
3-What do they offer that rpm --rebuilddb doesn't?
Because sometimes it doesn't work, and you need instead to replace the database. Happened to me /once/. Mind you, once is enough.
4-Why isn't rebuilddb in the rpm manual?
It is on another manual. Let me see if I can find it [...] no luck so far [...] man -K rebuilddb finds it. RPMDB(8) rpm {--initdb|--rebuilddb} [-v] [--dbpath DIRECTORY] [--root DIRECTORY] Use --initdb to create a new database if one doesn't already exist (existing database is not overwrit- ten), use --rebuilddb to rebuild the database indices from the installed package headers. Well, there it is :-) If you found "rpm --rebuilddb" in some doc, it is old and has not been corrected. It is "rpmdb --rebuilddb".
5-Why 30,000k per backup file? (My /usr is typically <3G total, including /usr/local/ which is on a separate filesystem.)
Mine are 110854615..113125097 bytes each. Don't complain :-P

Irrelevant :-) Anyway, I do not see the advantage of systemd timers.

You are right! It is there. I think it was previously 'rpm {--initdb|--rebuilddb} ...', and then moved to rpmdb. The documentation was just moved to another man, but not edited. Bug found! -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)
