Duplicity - 無法恢復單個文件

我嘗試通過來自亞馬遜S3的重複項來恢復單個文件或目錄，但是我得到一個錯誤。Duplicity - 無法恢復單個文件

Local and Remote metadata are synchronized, no sync needed. 
Last full backup date: none 
Traceback (most recent call last): 
    File "/usr/bin/duplicity", line 1251, in <module>

CollectionsError: No backup chains found

我做錯了什麼？

在這裏，我怎麼做備份出口PASSPHRASE = * *** 出口AWS_ACCESS_KEY_ID = * *** 出口AWS_SECRET_ACCESS_KEY = * *** GPG_KEY = * *** BACKUP_SIM_RUN = 1

trace() { 
     stamp=`date +%Y-%m-%d_%H:%M:%S` 
     echo "$stamp: $*" >> ${DAILYLOGFILE} 
} 

cat /dev/null > ${DAILYLOGFILE}
