可以从主目录的备份中排除哪些文件和目录？

Question

Duplicity在进行高效备份方面已经做得很好，但我仍然希望尽量减少要备份的文件数量。

主目录中可以排除哪些文件或目录？请明确命名这些，允许通配符，路径相对于主目录。

Answer 1

如果丢失，大部分文件和目录都会重新创建。它们主要用于降低应用程序的启动时间（Firefox 扩展缓存）、指示锁定 ( .gksu.lock) 或包含特定于会话的信息（例如 dbus 会话的 ID）。最近的文档经常更改，通常不太适合备份。

可以排除这些目录：

.gvfs                           # contains mounted file systems?
.local/share/gvfs-metadata
.Private                        # contains the actual encrypted home directory
.dbus                           # session-specific
.cache
.Trash                          # do I need to say more?
.local/share/Trash
.cddb                           # cached info about audio CDs
.aptitude                       # cached packages lists

Flash 专用：

.adobe        # Cache for flash, maybe others?
.macromedia   # except for Flash persistence, there is no reason to keep this

文件：

.xsession-errors            # contains errors from the current graphical session
.recently-used              # recently used files
.recently-used.xbel
.thumbnails
.Xauthority                 # session-specific
.ICEauthority
.gksu.lock
.pulse                      # directory
.pulse-cookie
.esd_auth

KDE 具体：

.kde/share/apps/RecentDocuments # Recent documents on KDE
.kde/share/apps/klipper         # Contains a history of the Klipper clipboard (KDE)
.kde/share/apps/okular/docdata  # you will loose saved scrolling positions of PDFs
.kde/share/apps/gwenview/recentfolders
.kde/share/apps/kmess/displaypics  # cached other users' profile pics
.kde/share/apps/kmess/customemoticons  # cached emoticons of others

Firefox 特定（另请参阅Profile 文件夹）：

.mozilla/firefox/*/Cache
.mozilla/firefox/*/minidumps    # in case Fx crashes dumps will be stored in this
.mozilla/firefox/*/.parentlock       # session-specific           
.mozilla/firefox/*/urlclassifier3.sqlite  # phishing database, recreated
.mozilla/firefox/*/blocklist.xml   # blacklisted extensions
.mozilla/firefox/*/extensions.sqlite  # extension database, recreated on startup
.mozilla/firefox/*/extensions.sqlite-journal
.mozilla/firefox/*/extensions.rdf
.mozilla/firefox/*/extensions.ini
.mozilla/firefox/*/extensions.cache
.mozilla/firefox/*/XUL.mfasl     # cached UI data, recreated
.mozilla/firefox/*/XPC.mfasl
.mozilla/firefox/*/xpti.dat
.mozilla/firefox/*/compreg.dat

Answer 2

好问题。我喜欢这些——我们可以在那里收集社区意见/列表并挑选相关的东西。这是我的.exclude文件。我将此文件作为多个脚本中的参数提供给rsync--exclude-file=（您也可以使用duplicity 执行此操作）。请注意，该问题暗示“您想要/需要保存什么”。例如，我备份我的完整.mozillaDIR，因为它包含多个配置文件和调整，并且更容易将其作为一个整体转储回磁盘。在我的配置中也暗示：我做了很多“从头开始安装”的测试。因此，我有一个已知良好的干净基础安装的clonezilla映像，并在将其添加到磁盘上后添加存储在 USB 上的个人（/home）数据；有时是选择性的，有时是整体的。

Answer 3

我在https://github.com/rubo77/rsync-homedir-excludes创建了一个忽略列表

您可以将其与 Duplicity 或 rsync 一起使用，如下所示：

rsync -aP --exclude-from=rsync-homedir-excludes.txt /home/$USER/ /media/$USER/linuxbackup/home/$USER/

这是定期更新的，目前我们已经有了：
