Évaluation des logiciels de backups connus.

Critères

Critères de base

Maintenance

• le logiciel doit être bien maintenu par une communauté, avec un package debian

Dernière mise à jour

• des mises à jour régulières

Libre

• un logiciel libre, bien sûr

Transport

• le transport des données doit être sécurisé

Incrémental

• garde un historique des backups sans dupliquer les données

Performant

• peut conserver des quantités massives de données, tant en terme de taille que de nombre, de façon efficace

Méta-données

• permet de conserver les permissions, ACLs, ownership etc

Documentation

• avoir une bonne documentation des procédures de restore et backup

Stabilité

• ne doit pas corrompre les données de temps en temps ou échouer les backups de façon consistente (peut seulement avoir des infos là dessus à l'usage)

Extra

Ceci sont des "nice to have", pas nécessaire pour notre application.

Encryption

• supporte l'encryption des données par le client

Déduplication

• déduplique les données entre les différents backups

il y a seivot qui est interessant, mais plein de bugs, et inutilisable.

Non-évalués

Ori FS

DVCS-style filesystem over FUSE that deduplicates data and stores file history.

http://ori.scs.stanford.edu/

• supposedly builds on Linux, FreeBSD and Mac OS X
• not packaged in debian
• low activity on the mailing list
• last release in january 2014
• last commit in january 2014

Backup pc

http://backuppc.sf.net/

• Packages for FreeBSD (?) and Debian

• Encrypted network support (ssh)

• Supports whole filesystem backups (also saves space on duplicate files)

• Documentation

• Maturity

• Backup design: pull
• suports windows workstations

To be considered for RdiffBackup replacement.

Running very well on communautique backup system. Has a nice web interface for status, job control and direct in place restore. Thumbs up. -- TheAnarcat 2007-07-04 12:57:43

xfsdump

The main disk was mirrored to the /backup script with xfsdump(8).

Unfortunatly, the xfsdump format (or the implementation) works very slowly. In fact, it is impossibly slow to restore data using it, so we are dropping it.

See /XfsDump for more documentation.

Cedar backup

http://cedar-solutions.com/software/cedar-backup/

• Packages for FreeBSD and Debian

• Encrypted network support (through ssh)

• Support for whole filesystem backups flaky (problems with UTF-8 in XFS) and sub-optimal

• Documentation good, could be better

• Maturity

• Backup design: pull, ssh, internal tar implementation

pros:

• easy to configure multiple hosts backed-up

problems:

• made to backup a discreete number of files
• flaky support for bizarre environments (had bugs with utf-8 filenames, resolved)

Cedar usage has been phased out. See lethe.koumbit.net/CedarBackup for legacy information

home-made rsync + hardlinks script

Inspired from: http://www.mikerubel.org/computers/rsync_snapshots/

http://lethe.koumbit.net/cgi-bin/cvsweb.cgi/koumbit-maint/bin/remote_backup.sh

• Packages for FreeBSD and Debian N/A

• Encrypted network support (through rsync + ssh)

• Support for whole filesystem backups too slow

• Documentation none

• Maturity custom script

problems:

• takes a lot of processing power and time to backup complete filesystems

See /RsyncAndHardlinks for more documentation.

Bacula

http://www.bacula.org/

• Packages for FreeBSD and Debian N/A

• Encrypted network support (through stunnel or builtin with tls... in the next release, 1.37)

• Support for whole filesystem backups

• Documentation

• Maturity

interesting features:

• sql-database of backed-up files
• completely decentralised nature: the backup directory can be on a server, have many storage servers, consoles on other machines, multiple clients, etc

problems:

• complex and hard to install
• network encryption is not built into the main release, only in the dev version. therefore requires stunnel or ssh forwarding.

See /BaculaSetup for installation and configuration.

burp

bacula fork - simpler and supports disk-based backups and rotation better and supports deduplication.

http://burp.grke.org/

Bareos

Bareos, or Backup Archiving Recovery open source, is another fork of bacula. It seems to be a 1:1 match of bacula 5.2 that continued efforts to make it move forward.

http://www.bareos.org/

Dirvish

Duplicity

http://www.nongnu.org/duplicity/

hdup

http://www.miek.nl/projects/hdup2/

• Packages for FreeBSD (?) and Debian

• Encrypted network support (ssh)

• Support for whole filesystem backups (?)
• Documentation (?) simple doc available
• Maturity (?)

interesting features:

• uses tar
• archive encryption (gpg)
• archive compression with gzip, bunzip, lzop or none
• incremental
• archive splitting
• remote backups over ssh
• supports the "one filesystem" flag to tar
• syslog support

problems:

• hdup suffers from the same design problem than cedar wrt offsite-only backups in that it stores local copies of the backed-up files and therefore doesn't stream them straight to remote which is a problem in thight diskspace environments.
• hdup must be installed on both machines (client and server) to work

amanda

• à tester: amanda

Mondo rescue

Barebones backup solution, allows creation of bootable cd images. Uses afio (tar replacement).

bdsync + bdbackup

bdsync creates a diff from two (maybe one local and one remote) block devices, and can apply such a diff to a block device.

bdbackup is a tool that can be used to keep a number of copies of diffs created by bdsync.

• bdsync's homepage: http://bdsync.rolf-fokkens.nl/

• bdbackup's project page: https://github.com/maxigas/bdbackup

Both weren't tested yet by koumbit staff.

ZBackup

zbackup is a globally-deduplicating backup tool, based on the ideas found in rsync.

http://zbackup.org/

Features:

• deduplication throughout all backups
• LZMA compression
• can encrypt data

No purging old backups

Back in time

Simple to use rsync + hardlinks desktop client.

http://backintime.le-web.org

restic

http://restic.github.io/

• deduplication, with an interesting new chunking algorithm

• encryption
• s3 support
• written in go

• can't delete old backups (and no schedule

• can't resume interrupted backups

• password shows up on the commandline

• no compression

• possible reliability problems with large datasets: https://github.com/restic/restic/issues/298,
