Most of these files and directories are recreated if missing. They are mostly intended for lowering the startup time of an application (Firefox extensions cache), indicating locks (.gksu.lock
), or containing session-specific information (e.g. ID of dbus session). Recent documents changes frequently and is generally not that sensible to backup.
These directories may be excluded:
.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-specific:
.adobe # Cache for flash, maybe others?
.macromedia # except for Flash persistence, there is no reason to keep this
Files:
.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 specific:
.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

.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/*/extensions.sqlite # extension database, recreated on startup
.mozilla/firefox/*/extensions.sqlite-journal
