The rsync method also seems to be faster for us on WANs as well. Just wanted to let everyone know if this hasn't been brought up. Trey Nolen I've had the reverse happen to me -- after the upgrade from Cygwin 1.5.25 to 1.7.1 my rscynd backups over pre-established ssh tunnels started hanging randomly after ~24 minutes. I've reinstalled Cygwin, installed on fresh Win 7 machines, turned off all anti-virus and firewalls, and still can't eliminate the problem. It is definitely an rsyncd issue and not a ssh one as the tunnel stays up and active waiting. I'll give rsync over ssh a try again, though.

Re: [BackupPC-users] Convergent encryption
Hi Adam, From what I've read, it looks like convergent encryption would solve all the cases you mention. 1) Any third party wouldn't be able to decrypt the files on the drive, even when the server is online or without full drive encryption. The server can't ever read file contents. 2) As with 1), administrators wouldn't be able to view file contents. The problem you mention of destroying pooling wouldn't apply, as the goal of convergent encryption is to still allow the pooling of identical files by encrypting them the same way on different machines. 3) The need for encrypted tunnels is still there, but at least file contents wouldn't be visible in transit. Cody Adam Goryachev wrote: Cody Dunne wrote: I recently ran into a paper on convergent encryption, which is a way of encrypting file blocks by their hashes.

I'm not sure if this has been suggested before, but a brief peruse of the archives didn't turn anything up. It seems like the arguments against encryption in the past found the pooling issue insurmountable. I suppose there are a number of issues which should be solved by any encryption/backup solution, but which issues each person needs solved are different. 1) In some cases, the idea is to stop any third party that happens to break into the backup server from retrieving the data. 2) In other cases, you also want to prevent the admin of the backup server from being able to access the un-encrypted data 3) I'm sure there are other scenarios as well, but those are best resolved with a VPN/similar solution. To solve (1) there are probably a number of solutions from using an encrypted filesystem, or similar, though I'm not sure how useful that is when you need to leave the filesystem mounted 100% of the time so that backups can occur when needed. Same applies for auto-mounting the filesystem just before a backup, if the system can automount, then so could an attacker... To solve (2) there are also a number of possible solutions, one of which was mentioned on this list recently (rsync + encryption) which involved creating an encrypted directory structure (copy of the data) and then using the standard rsync to backup this encrypted structure. The ideal solution (from my perspective :) ) would be to have a custom open source'backuppc client' which can be installed on any linux or windows system, which supports rsync-like backups, with optional encryption prior to sending the data. This encryption will probably destroy the concept of pooling (unless every encryption key is the same on all clients), but it does make use of the other 90% of what backuppc provides (scheduling, interface, etc) Of course, the 'custom open source client' would also solve a number of other issues such as allowing the client to select which folders/files to include/exclude in the backup etc Regards, Adam -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
[BackupPC-users] Convergent encryption
Hi everyone,
I recently ran into a paper on convergent encryption, which is a way of
encrypting file blocks by their hashes. The hashes (keys) are stored
with the blocks, encrypted with the public key of any authorized
readers. This allows a server to pool identical files, as they end up
having identical encrypted blocks. This would allow BackupPC to still
work as it does now. Naturally, file size, location, quantity, etc are
visible but the contents wouldn't be.
I'm not sure if this has been suggested before, but a brief peruse of
the archives didn't turn anything up. It seems like the arguments
against encryption in the past found the pooling issue insurmountable.
I appended bibtex for the paper below.

Our mechanism includes: (1) convergent encryption, which enables
duplicate files to be coalesced into the space of a single file,
even if the files are encrypted with different users' keys; and (2)
SALAD, a Self-Arranging Lossy Associative Database for aggregating

You're correct that it needs to be modified, but AFAIK that document

the $Conf{BackupsDisable} section, just not in the one you refer to.
Also there is (at least the appearance of) a bit of a passing-the-buck

The FAQ http://backuppc.sourceforge.net/faq/ says The FAQ has been

This is on the FAQ page, not the documentation page. The FAQ isn't
updated any more, but AFAIK the documentation is.
However the wiki http://backuppc.wiki.sourceforge.net/ says This wiki
is not intended to replace the excellent BackupPC documentation [link to
FAQ].
It doesn't actually link to the FAQ, even though it is in the same
directory.
Clearly these are contradictory and cannot both be right. Where should
the above correction about BackupsDisable be made, and who can make it?
and which is the current view on which documentation location is
accurate, and who can correct that?
Craig updates the documentation, so we can get him to fix it.

The problem is, when I go to run BackupPC I check the XferLOG for the computer, and I get an inet connect: Connection refused error on port 1873. I've narrowed the problem down to this: I run netstat -a from the Windows computer and see that TCP computer:1873 is not even listed. However, TCP computer:873 is in the listening state. Disabling the rsyncd service removes that line, and enabling it brings it back. It seems that even though I specified in rsyncd.conf, port = 1873, the daemon still listens on 873.

Re: [BackupPC-users] Revamping the Wiki
For those of you interested, you can see the current structure of the wiki at: http://www.cs.umd.edu/~cdunne/files/BPCWikiStructure.png Also, the NodeXL workbook for it is here: http://www.cs.umd.edu/~cdunne/files/BPCWikiStructure.xlsx (sorry, Windows/Office2007 only) If anyone wants to take a shot at modifying it send me what you get or an outline. Jergen, thanks for your offer to help. I agree with your assessment of the need to consolidate simplify the FAQ and Tips and Tricks, but would include the Common Configuration Issues section as well. Also we could enforce some simple style formatting guidelines throughout. I haven't heard from anyone interested meeting yet, but I'll still plan on having it for anyone who wants to show up.

[BackupPC-users] Revamping the Wiki
Hello everyone, I've been looking over the BackupPC wiki to find somewhere to integrate my own material, but it's in pretty bad shape. There's no consistent structure or formatting, and I remember from my initial experience with it that everything was very hard to find. There is a proposed structure page (http://backuppc.wiki.sourceforge.net/ProposedWikiStructure) but it is fairly old, has no discussion, and it's suggestions are only partially implemented. I'd be willing to do a lot of the cleaning myself, though I don't want to step on anyone's toes without talking with you first. Also, my knowledge of BackupPC is fairly limited to my setup (XP/Vista clients Ubuntu server). Who would be interested in a short meeting about this, say this Sunday at 12pm via Skype or IRC? My username for both is edallme. Also, please send any other suggestions you have to me or add them to the ProposedWikiStructure wiki page/discussion.

Hi Juergen,

Things start to run smoothly, backupPC is really nice to install and

But how do I reasonably proceed with password protection for client
rsyncd? To get started, I presently use $Conf{RsyncdAuthRequired} = 0; -
works nicely, but not protection.
As an alternative I see that I can set that variable to 1, but then I
must store the password in the config.pl file - which needs to be world
readable. Not a good solution either - are there other alternatives?
Instead of using the rsyncd authentication, you can connect over a ssh
tunnel that then uses the rsyncd on the client. You then limit rsyncd to
only accept local connections. That way you have ssh authentication as
well as encrypted transfer. See
http://www.cs.umd.edu/~cdunne/projs/backuppc_guide.html for one way to
do this.

Hi Anandx, anandx wrote: There is a cygwin+rsync package available on the backuppc sourceforge site, which can make it very easy to install rsyncd. If you don't need rsync for anything else, and are happy to use rsyncd instead of rsync+ssh, then I've found this to be a good solution. Saw the package, and after reading the readme, it sure wouldn't be a problem to install it. I have a question on this, enabling the rsyncd on windows machine, does it arise any security issues of any kind ? Yes, rsyncd doesn't encrypt the file transfer and the authentication is less secure than ssh. You can allay these by setting up rsyncd to only allow local connections and then using an ssh tunnel for the transfer. For a guide, see http://www.cs.umd.edu/~cdunne/projs/backuppc_guide.html Btw any ideas if Backuppc can be configured to backup certain hosts at different intervals and certain at different ? Basically i want a machine to be backed up daily and keep 7 days backup, then 4 weekly backups and no monthly and then another one, i only want the monthly backups. Absolutely. The schedule settings in the CGI interface allow easy individual client settings for full backups: FullPeriod (time between backups) and FullKeepCnt (the number of backups to keep, which can be exponential over time). Similar settings are for incremental backups.

Re: [BackupPC-users] Junctions on WinXP
Hi Jeffrey, Jeffrey J. Kosowsky wrote: Does BackupPC know how to treat NTFS junction points. They are analogous to *nix symbolic links but only work on directories. Based on a little test, it seems like BackupPC does not know about them since it seems to have copied over all the data -- i.e. it treated the junction as a real directory rather than as a symbolic-type link. The attribute file also seems to treat it like a normal directory. Now to be fair, rsync does the same, so some of this may be an rsync artifact. Also, my understanding is that Vista introduced a notion of Unix-like symbolic links. Does anyone know whether they are treated properly by BackupPC? (I don't have Vista around to test but it would even be interesting to know how rsync treats them). I'm not sure about NTFS junction points in general, but in my tests the new Vista junction points broke rsync by recursively creating extra-long pathnames. I wrote excludes that would get rid of all the ones Vista creates for you.

One change that will likely require updates beyond File::RsyncP is: Protocol 30 now uses MD5 checksums instead of MD4. I assume this would require changes to RsyncDigest.pm and maybe also FileZIO.pm to deal with this new digest format. Maybe also a new first byte (d8 anybody???). Still would be great to have an upgrade to fix Windows issues (which seem to be pretty prevalent). I too would love an upgrade to File::RsyncP. Until then, perhaps a warning should be put in the documentation about trying to use rsync with Windows clients. There isn't anything in there saying to avoid rsync, and it was not obvious to me in my initial research that it would fail.

Yes they are in separate lines. After opening the ssh-connection (a real
shell, but I will change this for the future) the script waits 10sec. If
I remove the sleep the connection fails, perhaps the tunnel isn't
really ready?
If the tunnel is working for you, this probably isn't the problem but
it's my only idea. I think if you removed the screen command, it would
wait until the ssh command was finished and tunnel was ready before
returning. If you put sleep 10 on the same line as the ssh command,
sleep gets run on the client. That causes the tunnel to remain open for
10 seconds after the ssh command executes, which gives BackupPC time to
connect over it which keeps the tunnel open. This would remove your need
to explicitly kill the tunnel, as it would finish after BackupPC is done.
If you do the sleep, I don't think you need screen or the
DumpPostUserCmd you have. The tunnel will close automatically if
BackupPC fails to start or once BackupPC finishes or fails.
This wasn't working for me, don't know why. But as I already said - I
don't think, that the ssh-connection is the problem. I can backup my
linux-pc with the same conifg using a ssh-tunnel, too.
My only other ideas for you would be to add -v and and --progress to the
RsyncArgs and run BackupPC_dump like you have been. You could tail
/var/log/rsyncd.log on the client, too.
I added it, no big different. But in the log of the client I found a
strange thing: The clients sends 27 (!) files more to the server than he
receives.
Unfortunately that is the limit of my experience. Does anyone else have
any ideas for Heinrich?

I'm not a Linux expert, so this is possibly irrelevant, but why are you

kill the tunnel easily after the backup? If you do the sleep, I don't

close automatically if BackupPC fails to start or once BackupPC finishes
or fails. I also removed the -q from the ssh command for some reason...
but I don't remember now.

in your script you have defined a variable username, but you didn't use
it for the ssh-command.
Thanks for letting me know! I'd appreciate any other additions/fixes you

Also, I recently changed the exclude lists on my guide to remove

haven't had the problem since.
My only other ideas for you would be to add -v and and --progress to the
RsyncArgs and run BackupPC_dump like you have been. You could tail
