Backup and bdb-logfile removal
I've been going all documentation I can find (FAQ/bdb-docs..) and I
still have some doubt whether I understand this correctly.
I run frequent dumps with slapcat to backup the database, but I still
need to cleanup the BDB logfiles and it would also be nice get faster
back online after a crash than you can from LDIF.
So I understand how to create a hot backup by copying the database files
(db_archive -s) and then the log files (db_archive -l) and runing
I can see that I can delete unused log files (db_archive [no options])
from the backup. But when is it safe to remove log files from the active
db_archive on the active environment lists fewer files than on the
backup (predictable enough).
The docs say that running db_archive -d can make recovery impossible.
OK... so I don't do that.
But what is required of my hot backup snapshot to know that I can delete
log files from the active environment? (and which?) and still not
influence the posibility for recovery.
Could anyone list a step-by-step procedure to create a snapshot for
backup and prune the log files from the active environment?
btw: openldap 2.3.30/ bdb 4.2.52 (debian) ... but I guess that's not so
PS: I expect still to do occasional slapcats just as an extra security
