[BackupPC-users] limitations

[Philip Parsons (Velindre - Medical Physics)]

Hi,

I notice the link to the backuppc limitations page hasn't been updated for a 
while.  Are the limitations mentioned in 
http://backuppc.sourceforge.net/faq/limitations.html still applicable to 
v4.4
 please?

Thanks,
Phil

Hi Sorin, Jeff, et al.

I am the one who contributed 
https://github.com/backuppc/backuppc/wiki/Build-Your-Own-Packages
and I am mostly lurking on the mailing list with a few posts here and 
there.


Disclaimer: My work was build on top of Benjamin Renard and already 
received contributions from i.e. Richard Hansen and a Github user named 
"wwuck".

I started with Raoul's packages for 4.0.x but they weren't being
frequently updated. I downloaded them and examined the package code -
all looked legit.

So, I used them as the basis for creating my own version with more
updated code.


Gotcha', thanks.
Will look into rolling my own upgrade eventually it seems.

I think Debian may use a newer stable release of BPC.
Maybe I can find something there. Till now, I've focused on Ubuntu 
packages

only.


FYI: I am packaging as time permits (job, family) and on the 
architectures used by myself or explicitly requested.  Thus, there might 
not be an up-to-date package that fits your environment.
However, I am definitely *very* happy to accept pull requests and/or 
other contributions.


Additionally, others started to build off of my work, i.e. 
https://launchpad.net/~rhansen/+archive/ubuntu/backuppc (though it seems 
it hasn't been updated to 4.4 yet?).



Having said that, there is also an effort underway to officially package 
BackupPC 4.4 for Debian.

It was recently submitted and is already available on testing.
You can find details here https://tracker.debian.org/pkg/backuppc
(Though I did not yet check the current status/differences)

Eventually, my plan would be to switch to the official Debian packages 
(that will also end up in Ubuntu somewhen) and continue my contribution 
there.


I would be hopeful that my package would fit your needs.
Feel free to get back to me with any questions and/or suggestions.

Cheers,
Raoul

I think the debian packages were the ones I stumbled upon and now have my
eyes on. :-)
Depending on when they filter through to Ubuntu, I might or not roll my own.

It also depends on family, job and time generally for me too.

The Kifarunix's guide seemed pretty complete otherwise.

Re: [BackupPC-users] Return to BackupPC

[Richard Shaw]

I've largely stayed out of the discussion since CentOS was not listed as an
option :) However, CentOS Stream will live on. I currently maintain
BackupPC for Fedora and CentOS/RHEL,etc, via Fedora EPEL.

I currently keep backups at home via a small CentOS Stream server so I am
likely to notice problems if they occur and am active on this mailing list
(when needed).

I also maintain a COPR for CentOS 7 so it has access to v4. I only mention
this because that repository has 10s of thousands of downloads so I believe
the package to be of very high quality and is obviously actively
maintained.

Just my $0.02 worth.

Thanks,
Richard

Re: [BackupPC-users] Return to BackupPC

[backuppc]

Thanks Raoul - very helpful information -- and without your webpage,
I would never have been able to get started myself...

Couple of questions:
1. You say on your webpage "libbackuppc-xs-perl Package ATTN Currently
   broken!"
   In what way is it broken?
   I haven't noticed any problems in building (or using) my own
   updated version of this based on your original 'debian'

2. Is there a reason that you use rsync-3.0.9 vs 3.1.3 supported by
   Craig upstream?  I know that previously I had trouble compiling
   >=3.1.12 using your 'debian' but I didn't really explore that
   further

3. Other than pulling in new upstream source and updating the version
   numbering, have you made any notable changes to the 'debian'
   directories on any of these packages over the past say 18 months.

4. When do you expect to switch over to the emerging 'official' debian
   4.x packages which just migrated over to 'testing' from 'unstable'?
   It would be good for all of us to consolide around a stable
   (semi)official package for Ubuntu (note I am still using 18.04).

Thanks Raoul for all your contributions!

Re: [BackupPC-users] Upgrade from V3 to V4 - Pool size growing for no obvious reason

[George King]

Hi everyone,

Sorry if I'm missing something obvious but would anyone have any ideas 
why my V3 pool is growing (hugely) after upgrading to v4.4.0.  It 
doesn't make sense to me.  Over 3 days it has grown from 219Gb to 383Gb 
and there is only one client that is not compressed (localhost) which 
has not backed up since the upgrade (subject of a different post).   The 
V3 cPool has also grown (16-28Tb, although the graph doesn't seem to 
show this) while the V4 cPool is static at 8.84Tb.  Thanks

Hi

I've upgraded from V3.3.1 to V4.4.0 on Ubuntu 18.04.05 LTS and it has 
gone pretty well, thanks to earlier help from this forum.  Most 
clients are successfully backing up but I've still got a few snags 
that I'm trying to work through.


The first one is that the Pool size is growing for no obvious reason.  
Should I be worried?


The graph below shows my pool and cpool during the change over from v3 
to v4.  I understand the new V4 cpool slice but what is strange is 
that the V3 pool is growing day by day (at the expense of both CPools, 
maybe).  The only client I had on pool backup was localhost (excluding 
/var/lib/backuppc of course) and I have not got that working under V4 
(see no 2 below), so I'm not clear why it is growing.  Any ideas?

I'm speculating a bit now, and trying to remember half-forgotten facts...
Isn't this expected when changing from v3 to v4, since two pools are active?

Eventually the v3 pool will be emptied and everything will be moved over to
the v4 pool.

IIRC, there should be a tool to convert the v3 pool to v4 and speed things
up.

Re: [BackupPC-users] Upgrade from V3 to V4 - Pool size growing for no obvious reason

[kingswindsor]

Yes, I'd expect v3 pools to go stay the same or down if anything but they are 
increasing in size.  And the pool files (either v3 or v4) should not grow 
anyway- all active hosts are set for compression.  

The documentation has these bits which are relevant

"V3 migration: nothing specific is needed. V4 can browse/view/restore V3 
backups.

"When a V4 backup is first done, BackupPC_backupDuplicate is run to duplicate 
the most recent V3 backup to create a new V4 backup. A "filled" view of the 
most recent V3 backup is used to create a "filled" V4 backup tree.
This step could be time consuming, since every file needs to be read (as a V3 
file) and written as a V4 file. However, the V4 pooling code knows about the V3 
pool, so it will move the V3 pool file into the V4 pool. So this duplication 
process doesn't burn a lot of pool storage space, but every file still needs to 
be read (to compute the MD5 digest) and "written" (really just 
matching/linking)."
