NAME

glastree - build live, daily backup trees

SYNOPSIS

glastree [options] sourcedir backupdir

DESCRIPTION

Builds live backup trees, with branches for each day. Users directly browse the past to recover older documents or retrieve lost files. Hard links serve to compress out unchanged files, while modified ones are copied verbatim. A prune utility (see glastreeprune) effects a constant, sliding window. You may repeat invocations to one backupdir with different sourcedirs. Intermittent backups will retain compression if runs are not more than sixty (60) days apart.

EXAMPLE CRON
# backup ~/Mail everyday at 5am
0 5 * * *    glastree Mail /backup
# as above, keeping only last 3 days
0 5 * * *    glastree Mail /backup; glastreeprune --days=3 /backup | xargs -- rm -fr
