Goals of the Backup Plan
We have a few servers we need to backup some at Duke University, some at the colo facility in Pheonix. Currently there is 34 GB of data backed up.
- CVS repos, But this will also include what ever VCS that gets implemented in the future.
- Databases there is some mysql and postgres databases that have scripted backups, we just need to pick up the dumps.
- wiki, The fedora wiki needs backing up.
- some other data on various servers.
- need to ensure that linux ACL support is included.
- security in the backup. Preferably ssh tunnel, if not stunnel, but not a vpn setup.
- possibly /home on NetApp but this would need quota limits imposed 5-10MB would be a good starting quota
- Weekly full backups and daily incrementals, keep 4 weeks worth of backups.
- ssh support
- Uses standard Unix tools, don't need client to restore can use tar and dump
- Requires client on each machine
- complex configuration
- stunnel for security
- Verification of files previously cataloged, permitting a Tripwire like capability
- Saves and restores POSIX ACLs
- Access control lists for Consoles that permit restricting user access to only their data
- built in email reporting.
- not currently in Fedora
- requires a daemon to be running on each host (though can be worked around with nfs)
- needs either postgresql, mysql or sqlite for backup database
- differentail and incremental backups are done on time stamps only. files moved in to backup tree with older timestamps will not be backed up
- Completely web based (for backups and restores)
- Very easy to use
- Can create individual configs on a per host basis or one global config for all hosts
- Stores identical files as hard links on the file system to save space
- Has ACL support on a per host basis (Would integrate well with our current Account system or a future one)
- Supports RSYNC over SSH (we won't have to install client software on the machines to get it to work)
- Perl based
- Perl based :-D
- Probably slower than other solutions
- Not currently packaged for Fedora
- uses ssh
- easily does differential backups
- written in python
- uses rsync
- supports ACL's
- no need for any daemons (
- command line restores
- no pretty configuration setup
- command line restores
- rdiff-backup needs to be installed on all machines
rsync and scripts
- simple to setup
- currently in place
- can use ssh
- harder to scale
- simple to mis-configure and waste disk space
