Cobian Reflector and Monolithic zip file generation error

[nquinteros]

Hello. I have recently migrated from Cobian 11 to Reflector 2.5.0 and imported all job lists from the previous version.
I require one of the jobs to do a compression to a monolithic .zip file, and while it appears as if Reflector is working normally, the .zip file is never generated.
After a while, or if I cancel the job, I receive the following message:

ERR 2023-10-07 11:05:01 An unexpected error has occurred: StartIndex cannot be less than zero.
Parameter name: startIndex
ERR 2023-10-07 11:05:01 Source: mscorlib Details: in System.String.Substring(Int32 startIndex, Int32 length)
in Cobian.Reflector.FSTools.GetTopDirectory(String directory)
in Cobian.Reflector.Engine.LocalBackup.checkDynamics()

in Cobian.Reflector.Engine.TaskBackupExecutor.startBackup(BackupTask subTask, String backupId, SourceDestination realSource, DateTime backupTime, Boolean lastDestination)
in Cobian.Reflector.Engine.TaskBackupExecutor.Process()

I need compression, because after the .zip file is generated, with another task I send that file via ftp to a NAS located in a remote site.
If I don't compress, the total size to be uploaded extends too much.
Does anyone have any idea of a solution?
Thank you!

1) What is the source of the task?
2) any filters?
3) Doea it work with 7z?

Hello. I answer your questions:
- The files to be backed up are located on other servers, other than the one on which "Reflector" is installed. I access them through UNC paths (\\server\resource\). This works correctly in "Gravity"
- I have filters by extension (for example: *.bak), and filters by date (for example: < 1/1/2021)
- Yes, it can be compressed by 7zip
Thank you very much for your attention!

Seems to be a bug in the Zip library then.. Will try to reproduce that somehow. Under the mean time you can use the 7z implementaion.

Hello. Were you able to replicate the error in generating the .zip file?
I wanted to know if they solved the problem to migrate to Reflector permanently.
Thank you!

Couldn't replicate the error. Will try again tomorrow.
