Hi,
I have tried to start vchanger long time ago but i found it a bit too
complex. Since then i am running following configuration:
Autochanger {
Name = local-sd
Changer Device = /dev/null
Changer Command = ""
Device = drive-0, drive-1, drive-2, drive-3
}
Device {
Name = drive-0
Device Type = File
Media Type = File
Archive Device = /var/lib/bareos/storage
Automatic Mount = yes
Always Open = yes
RemovableMedia = no
RequiresMount = no
Autochanger = yes
Drive Index = 0
Maximum Concurrent Jobs = 1
RandomAccess = yes
Label Media = yes
}
Device {
Name = drive-1
Device Type = File
Media Type = File
Archive Device = /var/lib/bareos/storage
Automatic Mount = yes
Always Open = yes
RemovableMedia = no
RequiresMount = no
Autochanger = yes
Drive Index = 1
Maximum Concurrent Jobs = 1
RandomAccess = yes
Label Media = yes
}
Device {
Name = drive-2
Device Type = File
Media Type = File
Archive Device = /var/lib/bareos/storage
Automatic Mount = yes
Always Open = yes
RemovableMedia = no
RequiresMount = no
Autochanger = yes
Drive Index = 2
Maximum Concurrent Jobs = 1
RandomAccess = yes
Label Media = yes
}
Device {
Name = drive-3
Device Type = File
Media Type = File
Archive Device = /var/lib/bareos/storage
Automatic Mount = yes
Always Open = yes
RemovableMedia = no
RequiresMount = no
Autochanger = yes
Drive Index = 3
Maximum Concurrent Jobs = 1
RandomAccess = yes
Label Media = yes
}
Storage {
Name = bareos-sd
Maximum Concurrent Jobs = 4
# remove comment from "Plugin Directory" to load plugins from specified
directory.
# if "Plugin Names" is defined, only the specified plugins will be loaded,
# otherwise all storage plugins (*-sd.so) from the "Plugin Directory".
#
# Plugin Directory = "/usr/lib64/bareos/plugins"
# Plugin Names = ""
}
Pool {
Name = default
Pool Type = Backup
Recycle = no # No recycling, volumes used once and
then truncated
AutoPrune = yes # Prune expired volumes
Action On Purge = Truncate
File Retention = 70 days
Job Retention = 70 days
Volume Retention = 70 days
# Use Volume Once = yes
Maximum Volume Jobs = 1
Label Format = "default-${JobId}"
Storage = local-sd
}
I belive this setup is a bit tricky but it works perfectly for me. The
trick is to have only one job per volume and having number of jobs limited
on SD level to the total sum of devices. I am not sure but i think it was
set that way in order to avoid having the same volume opened by multiple
jobs simultanously.
Hope this can be helpful but feel free to correct me if you find this
configuration to be a total mess.
PS. It is possible that this setup require a helper script in order to have
expired volume files (and jobs) correctly removed.
Kind Regards,
Bartłomiej
