Thanks very much Emanuel :-TU

Thanks Emanuel

This will be very helpful


Thanks! That is nice, and appreciated!

Any chance to get the full list of codes…?

Like my 101450:;msg361993#msg361993

Or 100050:

… and whatever else…?

Just thought I’d check - if it’s not too much trouble…?

No worries… Thanks!

??? Yeah, for example, What does code 29 mean

how about 108

The error is caused by sending an invalid http request to the server.

Regarding Error 46, “path is invalid” means the destination path. I got this right off the bat while setting up a scheduled backup. I had not already created the series of folders the job was to be placed in. So for example, let’s say you’re saving the backup to F:/Folder1/Folder2/Folder3/. You must already have in place Folder 3 in Folder 2, and Folder 2 in Folder 1.

Odd that the job won’t just create the folder series if it doesn’t already exist, or at least offer to.


This issue was fixed in 3.0 version, which is now in BETA stage.



How about code 66? Just got this one on a co-worker’s machine today.

Hi, I just updated to version 3.0, and got an error 59. Help please.

Can you also advise if automatic scheduling is still available in this version?


This error suggest a corrupted backup.
Can you please give more details.

No features were removed, so if by automatic scheduling you understand backup jobs that start automatically at a specific time interval, yes this is still available.



duh…thanks. not sure how I managed to miss it the first time through

I edited it after you asked :slight_smile:


Hi all,

getting this message: backup process failed with code 1.

Its every time when i try to make backup on shared folder on our network or even on network drive.

Anyone know what is wrong? Thanks all for help.



If you are using incremental/differential scheduled backups this might be the cause.
This issue is caused by an internal error and it was fixed.
An update will soon be available.
