Hi there,
I'm using an HP MSL2024 Tape Library. If i have a look at my volumes, I see
that bareos is only writing round about 3,7TB each tape:
| mediaid | volumename | volstatus | enabled | volbytes | volfiles |
volretention | recycle | slot | inchanger | mediatype | lastwritten |
| 397 | BKA659L6 | Full | 1 | 4,088,514,705,408 | 4,098 |
31,536,000 | 1 | 9 | 1 | LTO-6 | 2015-07-08 07:59:45 |
thats only ~60% of the maximum capacity. What could be the reason?
my Tape config:
bareos-sd.conf
Autochanger {
Name = HP-Autochanger
Device = Drive-1
Changer Command = "/usr/lib/bareos/scripts/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg3
}
Device {
Name = Drive-1
Drive Index = 0
Media Type = LTO-6
Archive Device = /dev/st0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
Spool Directory = /tank1/bareos-spool
Maximum Spool Size = 107374182400 #100GB
}
Pool:
# Vollbackups auf Tape
Pool {
Name = B2T-full
Pool Type = Backup
Recycle = yes
Auto Prune = yes
Volume Retention = 1 year
Volume Use Duration = 1 week
Storage = B2T-01
Recycle Pool = Scratch
Scratch Pool = Scratch
Purge Oldest Volume = yes
}
Pool {
Name = Scratch
Recycle = yes
Auto Prune = yes
Pool Type = Scratch
Recycle Pool = Scratch
}
Job:
# Kopiert alle Fullbackups aufs Tape
Job {
Name = "copy-full"
JobDefs = "DefaultJob"
Type = Copy
Pool = B2D-full
Level = Full
Schedule = "copy"
Selection Type = SQLQuery
Selection Pattern = "select * from Job where Level = 'F' AND JobStatus
= 'T' AND ClientID in
('3','5','10','17','18','19','20','21','26','27','30','32','36','38','41','48','49')
AND(endtime between (NOW() - INTERVAL '8' DAY) AND NOW());"
Spool Data = no
Priority = 11
}
JobDefs {
Name = "DefaultJob"
Type = Backup
Level = Incremental
Client = de-backup01-fd
FileSet = "linux-set"
Schedule = "WeeklyCycle"
Storage = B2D-01
Messages = Standard
Pool = B2D-incr
FullBackupPool = B2D-full
DifferentialBackupPool = B2D-diff
IncrementalBackupPool = B2D-incr
Priority = 10
Write Bootstrap = "/var/lib/bareos/%c.bsr"
Write Bootstrap = "|/usr/sbin/bsmtp -h smtp.contact.de -f \"\(Bareos\)
\" -s \"Bootstrap for Job %j\" backup@********.de"
# Run After Job = "/usr/local/sbin/bacula2nagios \"%n\" 0 \"%e %l %v\""
# Run After Failed Job = "/usr/local/sbin/bacula2nagios \"%n\" 1 \"%e %l
%v\""
Allow Duplicate Jobs = no
}
Thanks for every hint!
