I have PDF files on a folder. They should be moved on a tape for
archiveing. If this is successful done. the source files will be
delete. Then after some time, new files are in the source folder and
should be moved to the tape and so on. The tape should be a fast
recovery solution for us. If it's not useable -we can get the files
from the client. So this solution is only a faster way for us.
My plan is to define a pool like this:
Pool {
Name = Archive
Pool Type = Backup
Recycle = no # Bareos can automatically recycle Volumes
AutoPrune = no # Prune expired volumes
Volume Retention = 20 years # How long should the Full Backups be kept?
(#06)
Maximum Volumes = 100 # Limit number of Volumes in Pool
Label Format = "Archive-" # Volumes will be labeled "Full-<volume-id>"
}
Well, Label Format does not matter for tape storage. You also need to
specify a Storage which uses a tape device.
The job will be done manually as a full backup type.
So I'm right, that every new job will append on the tape until it's
full
Yes.
and then the next empty tape will used by using auto-labeling?
No, you will have to label your tapes in advance. If you have a scratch
pool, you can put unused tapes there, and Bareos will pick a tape from
there into whichever pool needs one. I don't really recommend it
though, I think it makes management more difficult, ie., you have to
check the database to see if LB1004L7 is an Archive tape or not. I
prefer to make my own barcode labels with separate number series for
different usage.
When using auto-labeling, it defines a new volume by taking the prefix
from the Label Format, defined at the Pool settings followed by
counting up - 0000 4 digits. In SD the device is defined with
LabelMedia = yes;
Oh, I was assuming you have a tape robot. Auto-labling may work on a
standalone drive.
Would it be possible to do manually label a tape, then add it to the
pool for using if needed?
Yeah, put it in the Scratch pool if you don't want to put it in the
Archive pool directly. Bareos will not start using the extra tapes
before the current tape is full, anyway.
Thanks Kjetil,
Now, after some month of using Bareos and understanding the system, I'm
thinking about to buy a Quantum SuperLoader LTO 7 with 16 slots ;-)
Your explanation describe exactly the way I want to go, figuring out in the
last days. Planing with the auto loader, I will do also my own barcode labels
and put it in advance to a storage pool. Cumulative long time archives will
not be placed permanently inside the auto loader and I can put it after 3 months
manually in and out.
Finally, can I discuss the following example:
I have to archive from 3 departments audio, video and print files as "cold
data",
stored on tape:
First, I will will do copy all audio files to a local hard disk on the same
host,
where the tape is connected directly, because copying files of the network from
different host a slower than writing to tape.
Second, creating a job, using "Enabled = no" for starting it manually via GUI.
Setting the client to the local fd,
Setting a file set, which points to a local directory, where the data are stored
from step #1
Setting also the storage to the tape
Define a pool where I have predefined some empty tapes
Now run the job and archive the audio files.
When finished successful, would it be a good idea to delete the collected audio
files from the hard disk and go ahead with copying now the video files and start
the job again or will it be better, to make for each types of data (audio,
video,
print) an own job with an own pool and so tape like named:
audio1, audio2 / video1, video2 ..?
Sorry for asking but you guys have more experience with such tape scenario than
a
green horn like me :-)
Thanks for your help,
Frank
