Backup
Backup is a module that creates exact snapshots of your filesystem
on a remote server without running of disk space.
Thanks to Mike Rubel for providing the essential ideas.
See here
for his excellent treatise on rsync/hardlink backups.
Backup uses a mixture of rsync, hardlinks,
Python, ssh-add and cron to create snapshots
- every two hours on the current day,
- daily snapshots in the current week
- weekly snapshots in the current month and
- monthly snapshots in the current year
all appearing as exact copies of the file system
as it looked on the date the snapshot was taken.
Platforms
This script was written for Debian Linux as local host
and Sun/SOlaris as fileserver. Other platforms might require
minor modifications.
