FLR to Linux System with Umlauts in path and filename

Post by tdeklein » Jan 23, 2019 10:06 am

Hi there,

we recently had a support case with Veeam regarding FLR of a backup from a Linux system to a Linux system. I was asked to post this here to make devel aware of the problem 'cause so far we have only a workaround that wont work in most cases.

Given is a backup from a Linux system and the need to restore somefiles. Starting the FLR App and selecting the files worked fine. Restore was extremely slow and stopped after about 5 to 10 MB (of14G). Veeam support pointed out the the release notes state under "known issues" that ssh operations on files and paths with umlauts are currently a problem and not working.

The workaround was to activate the root login in the FLR App and connect from the target system to the FLR App to get the files via sftp. That worked like a charm and at expected speeds.

Unfortunately this would be impossible for most of our systems, because between the FLR App and the systems that might need a restore there are firewalls that would allow a connection from FLR App to target system, but not the other way around.

One (hopefully) easy solution to the problem would be to use sftp instead of ssh for file operations in the FLR App.

I would be glad to hear about any other solution.

Cheers
Thomas

Maybe it's me missing something important, but how using SFTP going to be an easy solution for you considering the mentioned limitation being in place? Also, is the target VM hosted on VMware or Hyper-V?

Thanks!

Any chance this system is not UTF-8?

Hi,

thats my point: The workaround is for various reasons not a solution for production use :-). And we use VMware.

And here I obviously misunderstood your question. Let me rephrase my answer :-).

The problem we have is with the direction of the traffic flow. Since using sftp did not have the problem with special characters/umlauts that ssh has, I guess the solution would be to use (or even better make it optional) sftp instead of ssh for all file operations from the FLR App to the target.

Cheers
Thomas
