可以从主目录的备份中排除哪些文件和目录？

Duplicity在进行高效备份方面已经做得很好，但是我仍要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？请明确命名这些名称，允许使用通配符，路径是相对于主目录的。

如果缺少这些文件和目录，大多数将重新创建。它们主要用于减少应用程序（Firefox扩展缓存）的启动时间，指示锁（.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，因此备份通常不那么明智。

这些目录可能被排除在外：

.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

特定于Flash：

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

档案：

.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

特定于KDE：

.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

特定于Firefox（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

特定于Opera的文件（有关Superuser.com的相关问题：是否可以在Opera配置文件文件夹中的文件和目录上找到文档？）：

.opera/temporary_downloads
.opera/cache
.opera/thumbnails
.opera/opcache
.opera/icons
.opera/application_cache
.opera/widgets/*/cache
.opera/lock

好问题。我喜欢这些-我们可以在其中收集社区意见/列表，并从中挑选相关内容。这是我的.exclude档案。我将此文件作为多个脚本中的参数提供给rsync--exclude-file=（也可以使用duplicity进行处理）。请注意，该问题暗示“您想要/需要保存什么”。例如，我备份了完整的.mozillaDIR，因为它包含多个配置文件和调整项，并且更容易将其转储到整个磁盘上。我的配置中也暗示：我做了很多“从头开始安装”来进行测试。因此，我具有一个已知良好安装基础的clonezilla映像，并且将我的个人（/ home）数据添加到磁盘上之后，将其存储在USB中；有时是选择性的，有时是整体的。

我在https://github.com/rubo77/rsync-homedir-excludes创建了一个ignorelist

您可以将其与Duplicity或rsync一起使用，例如：

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

我最近一直在考虑做这种事情，并且我注意到我不想备份的主目录中的许多文件似乎都没有设置组权限。如果在其他系统上也是如此，则可以使用以下方法获得可能的可疑对象列表：

find ~ -not -perm -g+r

（尽管检查了输出，因为尽管我的邮件看上去大部分都不错，但是我的电子邮件收件箱也出现在列表上，我不知道它对其他人的作用如何。）

这对我特别有吸引力，因为我的主目录是加密的（包括文件名），因此手动排除列表将是PITA，而我应该能够使用组权限自动生成排除列表。

（我知道线程很旧，但是我认为这可能对某人有用。）
