User:Larivact/drafts/Synchronization and backup programs

From ArchWiki
Comment: WIP draft for Synchronization and backup programs.

Features to consider:

  • file metadata
  • symbolic and hard links
  • sparse files

Questions to help you decide on a solution:

  • Where do you store your backup? External storage medium or remote server?
  • Do you need to synchronize files between devices?


This article or section needs expansion.

Reason: Fill blanks. Migrate conflict resolution, handles renames, FS metadata, platforms. (Discuss in User talk:Larivact/drafts/Synchronization and backup programs)
