This has been a major pain
, and I'm only posting here in case someone has bumped into something similar and found a solution.
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
