Re: [Bacula-users] Unmount command (Re: eSATA / USB disks as media for Bacula)

IMHO, "mount/unmount" are very different operations for disk and
tapes. For tapes, it is acceptable to leave them "mounted" in the
drive, because a "rm -rf /" won't touch them. For disks, they are
made part of the filesystem namespace when they are mounted, so their
contents will get blown away by "rm -rf /".
That's scary to me... the only reason I'm using Bacula instead of just
RAID mirroring is that accidental or naive malicious attacks can wipe
out all my data. I realize that moving my backups to a secure offsite
location is the only way to prevent this fully, but I'm looking for
middle ground with convenience and some measure of safety.
I'm currently using the patches mentioned by Cedric Tefft at:
http://bugs.bacula.org/view.php?id=1361
in conjunction with:
Device {
Name = FileStorage
Media Type = File
Archive Device = /MY-DIR/volumes
Mount Point = /MY-DIR
Mount Command = "/bin/mount %m"
Unmount Command = "/bin/umount %m"
Requires Mount = yes
LabelMedia = yes; # lets Bacula label unlabeled
media
Random Access = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = yes;
AlwaysOpen = no;
Offline On Unmount = yes
}

[Bacula-users] simple (?) mount/unmount of USB storage device
Hi, I'm a long-term Bacula user, having used it for file and DVD volume backups in the past. I'm scratching my head over what seems like a really simple requirement, but I can't for the life of me figure it out right now. I have a large external USB drive on which I want to write file volumes, by mounting it as /var/lib/bacula/media I have everything working to create and rotate files in the /var/lib/bacula/media directory, but I want to leave the drive unmounted (and thereby less liable to corruption) as often as possible, so that bacula-sd "mount"s it as /var/lib/bacula/media to do the backup, and "umount"s it when the backup is finished. I've been messing around with the autochanger scripts, but just don't understand them enough to put something this simple together. Anybody out there have a suggestion for what to do?

[Bacula-users] long waits for "status dir" to complete and *unknown* volumes
Hi, all... I have Bacula 1.38.11-5ubuntu1 installed. Just recently, I believe our Bacula setup hit its first year anniversary, and so now our 365 day volume retention period goes into effect. It now takes a long time (several minutes) to complete a "status dir" command. To try to speed it up, I've run "myisamchk -o *.MYI" on all the Bacula tables on our MySQL server. I've also added the following indices (based on watching what queries bacula-dir was issuing via MySQLAdmin): mysql> alter table File ADD INDEX(JobId); Query OK, 2679492 rows affected (59.59 sec) Records: 2679492 Duplicates: 0 Warnings: 0 mysql> alter table JobMedia ADD INDEX(MediaId); Query OK, 13895 rows affected (0.15 sec) Records: 13895 Duplicates: 0 Warnings: 0 mysql> This has helped a little, but I'm wondering if there's anything else that I can do to make it snappier. My second question is that I just noticed "*unknown*" being returned for the volume on the scheduled jobs. Is this normal? I don't remember seeing this before. Here is the output I get from running bconsole. # bconsole Connecting to Director bacula-dir:9101 1000 OK: bacula-dir Version: 1.38.11 (28 June 2006) Enter a period to cancel a command. *status dir Using default Catalog name=MyCatalog DB=bacula bacula-dir Version: 1.38.11 (28 June 2006) i486-pc-linux-gnu debian testing/unstable Daemon started 13-Apr-07 17:40, 0 Jobs run since started.
