Re: [Bacula-users] Migrating jobs between different SDs (servers)
Hi Mariusz !
Welcome to the underrated migrating club ! :) I also tried to migrate
between SDs to no avail. I supposed that migration for us bacula users
using FILE storage systems would be implemented as well, but alas, it is
not.
Why did you want to migrate the files ? Something connected to expanding
a filesystem ? Because this is a feature of FILE based volumes, that
they are not easily extendable (as opposed to tapes) and migration could
be a good way to transfer data between old (let's say a 1TB LVM system)
and new (4TB netapp) storage systems.
Finally, I moved the volumes themselves to the new storage server (10X
400GB SATA disks), and "migrated" the old server's TCP/IP address to the
new server. bacula picked up from there and it eventually worked quite
well, except for the Intel 965 motherboard that is not well supported by
linux.
Cheers,
Michael

In fact I spent the last couple hours setting just such a system up, and was surprised when if failed with the tape SD looking for the disk SD's storage device. I then re-read the docs on migration, and it doesn't say anything about it. I'm sure anyone who was familiar with the code would not be surprised by this limitation, but it probably should be made explicit in the docs. The idea was to avoid slowing down my server waiting for a tape drive.

The problem is that those who have time to work on features don't have enterprise-scale systems and so don't work on enterprise-scale related features. Those who do have such systems don't have the time (and/or programming ability) to try and write such code. There is nothing stopping you from working on (or paying for someone to work on) the necessary code and then contributing it back into the feature pool. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

You should use spooling - as always with a decent tape drive IMO.

Hmm... This highly complicates my idea :/ Have to 'redesign' the whole
concepts...
BTW. If it was mentioned previously - is it possible to add "multi SD
migration" to the TODO list (question to developers, I think)? I hope
I'm not the only one to use this feature. IMHO it could be very
important in backing up multiple/distributed systems, where it is much
easier and cheaper to have one big library for long term storage then
equip every system/site with dedicated, smaller libs.

No, that's not possible. Perhaps it will be implemented some day - I
talked with Kern about this - but I'm quite sure nobody started
implementing this.

Not reliablility itself, but the duration of the jobs alone makes them
more easily affected by network problems.

[Bacula-users] Migrating jobs between different SDs (servers)
Hello,
I have yet another problem to solve. I didn't find similar case in
documentation.
I have two separate systems in two locations (let's say "site1" and
"site2"). In "site1" I have local DDS5 drive and TS3310 library. In
"site2" server is only equiped with DDS5. Also, "Site1" is accesible
from "Site2" via WAN. So, "Site1" configuration looks like this:
Site1:
- StorageDaemon1:
* device: filesystem-1
* device: dds5-1
* autochanger: ts3310-1
- Director1:
* storage: filesystem-1 (@StorageDaemon1)
* storage: dds5-1 (@StorageDaemon1)
* storage: ts3310-1 (@StorageDaemon1)
* pool: localfiles-1
+storage: filesystem-1
* pool: localtape-1
+storage: dds5-1
* pool: tapelibrary-1
+storage: ts3310-1
I plan to backup backup hosts to pool "localfiles-1", then migrate it to
"tapelibrary-1". "localtape-1" will be used for backupserver itself.
Expect no problems with it. Then, "Site2" conf:
Site2:
- StorageDaemon2
* device: filesystem-2
* device: dds5-2
- Director2:
* storage: filesystem-2 (@StorageDaemon2)
* storage: dds5-2 (@StorageDaemon2)
* pool: localfiles-2
+storage: filesystem-2
* pool: localtape-2
+storage: dds5-2
Again, I plan to backup backup hosts from "Site2" to pool "localfiles-2"
and "localtape-2" will be used for backupserver itself. Expect no
problems with it, either.
We could not buy a dedicated library for "Site2", OTOH TS3310 in "site1"
is big enough to hold backups from both sites. So, I thought about
migrating jobs stored in "localfiles-2" to a library via WAN connection.
IHMO I should add such items:
Site2:
- Director2:
* storage: ts3310-1 (@StorageDaemon1)
* pool: tapelibrary-2
+storage: ts3310-1
So I could migrate locally stored jobs from "fileststem-2" to
"tapelibrary-2" which resides on remote ("Site1") library.
!!
My question is: are there any weak points in this idea? I.e. is it
possible to migrate between different storage daemons? Can [slow] WAN
connection (some 2 Mb/s I think) affect backup reliability?
!!
Any comments and suggestions are gratly appreciated.
