Backup4All FTP Problems
« on: April 17, 2008, 06:32 AM »
This has been a major pain  :'( , and I'm only posting here in case someone has bumped into something similar and found a solution.  :tellme: :tellme: I've been in contact with the Backup4All developer, the Hosting provider, the router manufacturer  :( and we seem to be running in ever diminishing circles with most people excusing themselves, understandably, and saying it's not their responsibility.

OK: What's the story:
I've got a paid-up latest version of Backup4All Pro that I'm using, amongst other things, to back up off-site, via FTP, to my Windows hosted site at LunarPages.com.

No problems at all locally. Plenty of FTP problems though. B4A almost seems incapable of overwriting a file, not all the time, but when it fails (99% of the time) it always fails when it's trying to write a file that exists on the FTP server. It'll do an initial backup and FTP it to my site without problems. When I do another backup, it'll successfully FTP the next *.zip but fail with the catalog.

The B4A devs have investigated the log files and catalog and said the failure is caused by:
The problem is that the FTP connection is interrupted during the backup.
-B4A Developers

I tested B4A using some free FTP space over at 0catch.com and it performed fine without problems, using exactly the same backup job (just changing the destination).

I tried the FTP backup to my site with SyncBackSE and it performed without problems (obviously using the same FTP account: therefore it's definitely not permissions).

So I think I can presume:
  • It's not a router issue as SyncBack works on my site, B4A works on 0catch.com and Filezilla works on my site.
  • It's not a permissions issue as SyncBack works fine.
  • It's not my site, as SyncBack works on my site as does Filezilla
  • It's not B4A, as it works on 0catch.com

It can only be the combination of B4A and my site??? Is that possible  :-\

Just a wild guess : did you change your TCP/IP settings with any kind of "Internet Accelerator" ?  If Yes, try to revert to windows defaults.  Most TCP/IP tuning tools allow that, try for instance a free one : Ashampoo Internet Accelerator 2.

Thanks MerleOne: but no  :(

My best guess at the moment is some incompatibility between B4A and another programme running here... I'll just have to take some time and find it... tomorrow

Are you using Passive mode FTP (http://www.backup4al...m/passive-mode.php)?  Passive mode works much better when going through a NAT router.

My experience is that the version of Samba on the linux machine can pose problems (I have the exact same problem here in a "mixed" LAN network, only SyncbackSE is able to make backups)  :(  Still, I'm looking for an answer for this one.

Definitely Passive. Even tried Extended Passive.

The dev asked me to try Active, but it didn't get off the ground.

That's interesting. I didn't find any problems backing up to my NAS (once I got the temporary folder set correctly)  :)

Yes, this is definitely driving me crazy...

Right now I'm a happy person, because I did find a solution (to my problem at least ;D).

http://areca.sourceforge.net/ is the way.

Not such a nice GUI (in version 5.5.5.5) but is very capable and once setup I can access it through the commandline for scheduled backups.

Right now I am too!  :D

The Backup4All developers identified that the FTP Server was not responding correctly to a SIZE command sometimes, they've amended their application and it works a dream!!

Mind you: it doesn't answer any questions  >:( Apparently it's a standard Windows2003 & IIS install, so why would it be mucking up just with Backup4All, or are all other softwares taking a similar approach to get around that "bug"??

But, anyway: the upshot is that the problem is fixed (and all the Help Desks were very helpful too)!
