Symptoms

Backup to FTP task fails:

Error: server "server"  
Cannot export dump file 'backup_info_1701202300.xml' to 'ftps://username@192.0.2.2
[Repository error: File'backup_1701202300.zip' not found]
Error:
Repository error: File 'backup_1701202300.zip' not found

psadump.log with debug mode enabled shows failed FTP directory listing:

[2017-01-27 23:02:11.656|4908] Debug: CurlError[8a20bdc1-acf7-49a2-a236-7a38ce7ada86]: Curl error: Failure when receiving data from the peer [..\..\..\..\..\common\plesk-utils\PMM\repository-transport\ftp.cpp:680]  
plesk::tFtpConnection::ListEx  
[2017-01-27 23:02:11.656|4908] Debug: TransportError[adfa6747-68a4-4df9-84e5-7b7816da7416]: Transport error: unable to list directory: Curl error: Failure when receiving data from the peer [..\..\..\..\..\common\plesk-utils\PMM\repository-transport\transport.cpp:905] plesk::tRepositoryFtp::ListDirEx

The issue appears when the same task is triggered twice within one minute.

Cause

The backup filename contains timestamp split to minutes: yyMMddHHmm. Therefore, the first and the second backup use the same file and the first process removing the file just after it finished uploading.

This is Plesk bug with ID #PPPM-5728 that was fixed in Plesk 17.5.3 #MU7.

Resolution

Install the latest Plesk micro-updates .
