I've just done another one which might be useful...
I keep backups on disk for about a week over a month, then
I migrate my Differential and Full backups to tape for safe
keeping. Bacula doesn't purge media when all jobs from a
virtual tape have been migrated to physical tape, so the
disk jobs stay around for the full life of the job. In my
case that means my Full backups would live on disk for
9 months, even though they were migrated to tape almost 8
months ago.
So, I need a way to find all MediaId's which have had *ALL*
of their jobs migrated to tape so that I can purge them.
Here's what I've come up with. (If there's an easier way
to do this, please tell me). (Works on MySQL)
:Test List Migrated Jobs stored on Media
*Order by (Job or Media):
!DROP TABLE tempmig;
!DROP TABLE tempmig2;
!DROP TABLE tempmig3;
CREATE TABLE tempmig (MediaId INT, Type BINARY(1));
CREATE TABLE tempmig2 (MediaId INT, Type BINARY(1));
CREATE TABLE tempmig3 (MediaId INT NOT NULL);
INSERT INTO tempmig
SELECT JobMedia.MediaId,Job.Type
FROM Job,JobMedia,Media
WHERE JobMedia.MediaId=Media.MediaId
AND Job.JobId=JobMedia.JobId
AND Job.Type='M';
INSERT INTO tempmig2
SELECT JobMedia.MediaId,Job.Type
FROM Job,JobMedia,Media
WHERE tempmig.MediaId=JobMedia.MediaId
AND Job.JobId=JobMedia.JobId
AND Job.Type!='M';
INSERT INTO tempmig3
SELECT tempmig.MediaId
FROM tempmig
LEFT JOIN tempmig2
ON tempmig2.MediaId = tempmig.MediaId
WHERE tempmig2.MediaId IS NULL;
SELECT DISTINCT
Job.JobId,JobMedia.MediaId,Job.Name,Job.Type,Job.Level,Job.JobStatus AS
Status,Job.JobFiles AS Files,Job.JobBytes/(1024*1024*1024) AS GB
FROM JobMedia,Job,tempmig3
WHERE JobMedia.JobId=Job.JobId
AND JobMedia.MediaId=tempmig3.MediaId
ORDER by JobMedia.%1Id ASC;
!DROP TABLE tempmig;
!DROP TABLE tempmig2;
!DROP TABLE tempmig3;
