[BackupPC-users] AsperaSync?

[Moorcroft, Mark (ARC-TS)[Analytical Mechanics Associates, INC.]]

Has anyone looked into dropping the paid AsperaSync or perl module parsync into 
BackupPC to replace vanilla rsync?

What is it about clicking Send that improves reading comprehension?  Right 
on the page (http://www.michaelstowe.com/backuppc/ ) is a link to the 
Github page:  https://github.com/mwstowe/BackupPC-Client

In my defense, it was way at the end of a blurb about a specific older 
version, but still...  :(  (Paragraphing FTW!  :)  )

Excellent!  Your statement above caused me to do some extra searching.  A 
couple of things:

1) I was using a much older version.  I can't find the installer I used at 
the moment, but I'm pretty sure it was 1.1, and almost certain it was from 
the goodjobsucking.com site and not the michaelstowe.com one.  In fact, I 
*did* look for an update before I wrote something:  but I was looking at 
the old site.  I didn't even know about the new one.  So, you *have* 
updated things -- and significantly! Yay!

For others:  Michael seems to be shy to link people to his work.  So, I'll 
do it for him:  http://www.michaelstowe.com/backuppc/

2) I looked for a github site for this software and couldn't find one, 
including searching for various permutations of "backuppc github".  I 
probably don't need it with the updated items linked above, but would you 
mind sharing it?

Again, thank you very much for the updates!  I'm excited by being able to 
lazy-install it on Windows Server 2012 now, as well as  maybe using it on 
my multi-drive servers!

So I still collected some 4.4 GB of caps, split them into chunks of 10
mio each and this is what I can see:

The last ACK from the backup server to the client:

81873   144.097589  10.8.80.6   10.21.32.5  TCP 52  1 → 
873 [ACK] Seq=1
Ack=73045447 Win=1321 Len=0 TSval=1701819479 TSecr=193052428

Then a series of Spurious Retransmissions from the client to the Server:

81874   172.857945  10.21.32.5  10.8.80.6   RSYNC   1406[TCP 
ZeroWindow] [TCP
Spurious Retransmission] Server MOTD

Followed by several Dup ACK from the server to the client:

81875   172.857979  10.8.80.6   10.21.32.5  TCP 64  [TCP 
Dup ACK 81873#1] 1
→ 873 [ACK] Seq=1 Ack=73045447 Win=1321 Len=0 TSval=1701826669
TSecr=193052428 SLE=73003473 SRE=73004827

And finally the client sends a reset:

81884   172.862230  10.21.32.5  10.8.80.6   TCP 40  873 → 
1 [RST, ACK]
Seq=73004827 Ack=1 Win=0 Len=0

Now, I'm not an expert at reading TCP streams, so I'd be grateful if
anyone could point out what I need to be looking for, or how to
interpret this data.

Looks like the Windows client is ending the connection, but does anyone
see why from this?

I can't tell what happened, but this time around (with rsyncd, not
ssh+rsync) I'm seeing "same" on the second attempt.

Also, it managed to get more files this time around than at any previous
attempt, so it created a new partial backup.


Best regards,
David

Re: [BackupPC-users] BackupPC-3.3.1-1.el6.x86_64 and Windows 10

[Stephen]

A stab in the dark: which smbclient are you running on your backuppc 
server? My guess is it's older than 4.0 (which supports SMB3, nee SMB2.2), 
and probably older than 3.6 (which introduced SMB2 support).


My colleagues that support windows tell me that Windows 10 disables SMB1 by 
default. There are valid security reasons for preferring SMB2/3 over SMB1 
(see ).


If you want to verify and/or resort to allowing SMB1, on your Win10 
machine, use regedit to BACKUP your registry, then search for and change:


HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
SMB3=0
SMB2=0
SMB1=1

Create these DWORD entries if they do not exist. Reboot when done. Note I'm 
not responsible if you screw up your machine. Educate yourself before 
blindly following strangers' directions.


Hope this helps.

Cheers,
Stephen

Hello all,

 

   I’m using smb to backup my Windows 7 computers with BackupPC.

 

Windows 7 x32 and Windows 7 x64 Backup just fine…

BackupPC-3.3.1-1.el6.x86_64

CentOS 6.7 running  /kernel-lt-3.10.93-1.el6.elrepo.x86_64 (elrepo)

HP ProLiant ML310e Gen8 v2, 6GB ram, mdadm raid1 (/dev/sdb,/dev/sdc) w/ lvm 
1.5tb partition, ext4

 

Everything works fine….

 

Question:

    After a hard drive crash my cad workstation guy wanted to move to Windows 
10. My problem is now, BackupPC won’t backup his workstation and another 
Windows 10 preview
test computer I have.

 

The initial problem is “No files dumped for share C$”. That translated to I 
need some sleep and got the user/password for the C$ setup correctly on Windows 
10 and since
I use the Administrator account, typed “net user administrator /active:yes and 
an administrator cmd prompt. On my test machine, it wasn’t backing up all of the
directories, ie c:\users, etc. In messing with the Windows 10 permissions, even 
with running full backups, it’s only backing up a file or two (seems at random 
or only
changed files)

 

Now ‘m down to the point of it not backing up anything again and back to the 
“No files dumped for share C$” error.

 

From Google searches, it doesn’t appear anyone is using or has tried backing up 
Windows 10 via BackupPC.

 

Any suggestions would be appreciated.

 

Kind regards,

 

Richard

CGI didn't have permission to the file, once I gave CGI the appropriate 
permission the two graphs showed up.  Prior to that I just got 
placeholder icons, no images.
