rdiff-backup - 備份文件夾小於原始/恢復文件時出錯

我正在測試 rdiff-backup，我想也許有人可以幫助我。1：為什麼我的備份比原來的文件夾小？在我的遠端伺服器中，我有 36G，而在我的備份伺服器中，它只有 29G。

2：我試圖恢復一些文件，但我得到了這個錯誤：

Exception '[Errno 13] Permission denied: '/home/brt/backups2/rdiff-backup.tmp.0'' raised of class '<type 'exceptions.OSError'>':

Fatal Error: Lost connection to the remote system

發生了什麼，我該如何解決？

謝謝你。

看起來像權限：OSError：

$$ Errno 13 $$權限被拒絕：’/home/brt/backups2/rdiff-backup.tmp.0' 聲明它被拒絕訪問此文件/目錄，從而導致連接失去。

還請檢查是否有足夠的可用空間
