Has anyone been able to use cloud storage reliably with Bacula 11? I am trying
to convert from using volumes on local disk to using minio as a cloud service
without much luck.
The odd thing is, it will work for a time. But if bacula-sd or bacula-dir
restarts, I end up in a state where the device status shows things like:
> Device Cloud (S3 Plugin): "cloudDrive-01" (/tmp/cloudDrive-01) is not open.
> Device is BLOCKED waiting for mount of volume "rpi-0002",
> Pool: rpi
> Media type: CloudType
> Drive 0 is not loaded.
and I don't see any obvious way to force it to mount the cloud storage into
that device node -- short of running s3fs to mount the volume as if I was doing
a restore. I would think that would not be needed since this mount request is
from a backup.
Restores are another problem, as I have yet to get one to work reliably with
cloud media. Maybe I just need to tune my settings a bit more, but doing a
mount of a volume with lots of small files via. s3fs is painful at best, and
doesn't work at all in the worst case. Having to mount that under a specifc
directory when I'm running bacula-sd in a docker container is even more
painful, since it requires reconfiguing and restarting bacula-sd any time I
want to restore something.
Here's a sample of my config (with passwords/hostnames obsfucated of course):
> Device {
> Name = cloudDrive-01
> Device Type = Cloud
> Media Type = CloudType
> Archive Device = /tmp/cloudDrive-01
> AutomaticMount = yes
> AlwaysOpen = no
> RemovableMedia = yes
> Label Media = yes
> Random Access = yes
> Autochanger = yes
> Maximum Part Size = 50MB
> Maximum File Size = 50MB
> Cloud = minio-nas
> }
> Autochanger {
> Name = CloudAutoChangerS3
> Changer Device = /dev/null
> Changer Command = ""
> Device = cloudDrive-01, cloudDrive-02, cloudDrive-03, cloudDrive-04
> }
> Cloud {
> Name = "minio-nas"
> Driver = S3
> HostName = "nas.xxx.com:9000"
> BucketName = "bacula"
> AccessKey = "bacula"
> SecretKey = "xxxxxx"
> Protocol = HTTP
> UriStyle = "Path"
> Truncate Cache = "AfterUpload"
> Upload = "EachPart"
> Region = us-xxx-1
> MaximumUploadBandwidth = 100MB/s
> }
