problem with scheduled backup in NG secure platform

[peteralm]

I would like to schedule backups from our configuration on cp ng secure platform (via secure web interface), but cannot get this scheduled task to work properly.

In the past I've configured tftp as our backup option. Everything seemed to work fine, but it occured to me that all files ended up the size of 32Mb. Some investigation learned that a default limit of 32Mb with TFTP is available (on 32-bits with a word of 16 bits giving default block size 512 * 65535=32Mb)and all our backups ended with this maximum size, but were corrupted.

I started experimenting with scp. Installed openssh on our Windows server and I am able to manually make succesfull backups. When however I try to schedule the backups, the backup fails with the message in our Windows event log": "sshd : PID 28860 : Failed password for cpbackup from 10.41.232.1 port 10209 ssh2". This even happens if I use the command line syntax from our firewall module. I am absolutely sure that the passwords I use are correctly and they should work as manual backup does work with the same password. All scheduled backups fail however and I don't know where to look now.

Any help would be appreciated very much.

It seems that I have to be worried about my problem as I'm seeming to be the only one having this problem?

look out for a version of tftp which runs as a service and you get rid of the problem you can use this one for example http://www.solarwinds.net/Toolsets/C...FTP-Server.htm

Sorry lmhost,

We did use this product already. tftp does not give a problem with the file transfer process itself, however it chops the files after 32Mb (due to block size and number limits) as mentioned in my first post. The files are not completely transfered after the tftp which seems to finish correctly (corrupted tar due to incomplete sending).

Therefore I think I have 3 alternatives:
1. make my backup manually started from webgui with scp
2. Use a tftp server that is able to change blocksize
3. solve my scp problem as this scheduling is a
Checkpoint given option that in my opinion should work
(noone else seen this problem?).

thanks for your reply anyway.
Any new suggestions will be welcome.
