Hello,
first, thanks for your answer.
I'm using using the Debian packages.
As i can see in changelogs
(https://metadata.ftp-master.debian.org/changelogs//main/b/backuppc/backuppc_4.4.0-3_changelog),
there is no problem.
my concern was more about compatibility between backups made with
backuppc 3.3.2-2 and backuppc 4.4.0-3, as well as compatibility of
configurations.
I don't see any such concerns anywhere.
So I can go with my eyes "almost" closed?
No risk to see my current backups (backuppc 3.3.2-2) disappear
About your note "version 4.x of BackupPC
"version 4.x of BackupPC does not traverse filesystems"
I'm not quite sure what that means.
I guess it's because I don't use this feature?
Thanks again

Hi there,

I am upgrading debian servers currently "Buster" to "BullsEye".
I notice that backuppc is upgrading from
3.3.2-2+deb10u1 (buster) to version 4.4.0-3 (bullseye).
Are there any prerequisites before upgrading or is there nothing to do?
Will the configurations and backups still be correct?
YMMV. My personal approach will (as always) be to allow some of the
inevitable problems to appear - and be ironed out - before I upgrade
anything to Debian 11.
Assuming that you are using the Debian packages, I would expect that
the Debian maintainer will document any changes necessary in the
information accompanying the package upgrades.
There are some significant changes. I would note in particular that
without a change to the default configuration, version 4.x of BackupPC
does not traverse filesystems. See the archives of this mailing list
for more information, e.g. search for '--one-file-system'.
Hi, from my experience (I followed bullseye when it was testing) :
Watch for $Conf{PoolV3Enabled}, you likely need it set to '1'.
The biggest catch is that you need to rewrite your $Conf{RsyncSshArgs}
line if you are using rsync over ssh. The exact syntax depends on your
setup, but there's a generic example in the docs shipped with the Debian
package. There are also discussions here and there online but the
documentation on the subject is seriously spread over the internet, and
lacking. That is as far as I know, please someone correct me.
Also if you are using rsync as your method, the '--one-file-system'
default option can cause some pain. If you have anything mounted under
the root of you backup, you will have to choose between having that
mount point backed up as a separate root (with '--one-file-system'), or
under the mount point (without '--one-file-system'). Personally I never
could make a "/home/user/mount" filesystem be backed up separately with
'--one-file-system', I resorted to remove the option and get everything
under the same root backup.
Hope it helps.
