Introduction

A Simple Backup Solution for Ubuntu should comprise of snapshot functionality – to restore to the last known good configuration of a single file, directory or a directory tree.

Rationale

User expects from their favorite OS the possibility to perform some sane and simple backups of their system.

Scope and Use Cases

  • James Troup's laptop has been stolen, he wants his data back.
  • HELP! my laptop is on fire! I must restore my music files somewhere else!
  • Hey somebody on #ubuntu told me to run sudo rm / -rf and now nothing works.
  • Matt accidentaly deleted his quaterly report and wants to get it back as new as possible
  • Pete deleted some very important piece of text from the product description document on Tuesday, he wants to get a copy of this document from Monday's backup to copy that text into the current version

Implementation Plan

  • user can configure a backup solution for his files - Recommended config or Custom config, Size requirements estimation - Includes: directory selection with default of the whole home directory ( system defaults to /etc, /opt, /usr/local, /var )

    - Excludes: checkboxes for common dirs and file types + textbox for regexes + maxfilesize (default to exclude ~/backup subdir, all media files (avi,mp3,wav,ogg,mpg) + all files >100 Mb, system level also excludes /var/backup) - Format: format selection and compression level selector (default: individual gzip level 9) - Destination: local dir, remote ssh session (default: ~/backup or /var/backup/)

    - Time: frequency (hourly, dayly, ...), type (full, incr), how long to store, timepoint (default: weekly full backup & daily incremental)

  • user can see how much disk space the backup will take
  • user can switch to admin mode
  • admin can configure backup solution for all users
  • package list is backuped
  • if admin allows this, users backup preferences override admins instructions

Note: incremental here means 'backup all files that have been changed (mtime) since the last backup'. diffs are not involved, as that would create a lot of complication for remote backup and lots of disc usage for the local ones.

  • Investigate dar as possible backend for multicd/dvd backups and can use other several kind of storage devices.

Data Preservation and Migration

None

Packages Affected

None

User Interface Requirements

  • GUI to configure the regular backups
  • GUI to recover files/directories

Outstanding Issues

  • dar cmd-line is complex.

  • During the BOF session, discussed system-level snapshoting as being the only way that could allow rollback and keep a consistent system, meaning at the whole filesystem is in sync with the contents of /etc. Looked at dm-snapshot target. If this can be made to work without wasting excessive amounts of space (eg, too many extra partitions) then this would be the ultimate foo, meaning that somebody could upgrade to Hoary, click 'rollback' and have their system come back exactly as it was 24hours early. This would require alot of investigate but maybe something is worth following up as a unique selling point.
