Hi,
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 db_recover -c.
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 environment? 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 important here.
regards, Peter
PS: I expect still to do occasional slapcats just as an extra security measure.
