口是心非还原会产生错误“未找到备份链”

Question

我正在测试口是心非的恢复功能：

duplicity restore file://fullSystemBackup/ backupOutput

这会产生以下错误：

Local and Remote metadata are synchronized, no sync needed.
Last full backup date: none
GnuPG passphrase for decryption: 
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1546, in <module>
    with_tempdir(main)
  File "/usr/bin/duplicity", line 1540, in with_tempdir
    fn()
  File "/usr/bin/duplicity", line 1391, in main
    do_backup(action)
  File "/usr/bin/duplicity", line 1468, in do_backup
    restore(col_stats)
  File "/usr/bin/duplicity", line 731, in restore
    restore_get_patched_rop_iter(col_stats)):
  File "/usr/bin/duplicity", line 753, in restore_get_patched_rop_iter
    backup_chain = col_stats.get_backup_chain_at_time(time)
  File "/usr/lib/python2.7/dist-packages/duplicity/collections.py", line 971, in get_backup_chain_at_time
    raise CollectionsError("No backup chains found")
CollectionsError: No backup chains found

这个错误是什么意思？

Answer 1

里面的路径file://fullSystemBackup/应该是绝对路径...

所以我做了file://"$PWD"/fullSystemBackup/...
