.SH NAME
.PP
glastree \- build live, daily backup trees
.SH SYNOPSIS
.PP
.B glastree
[options]
sourcedir
backupdir
.SH DESCRIPTION
.PP
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
.I backupdir
with different
.IR sourcedir s.
Intermittent backups will retain compression if runs are not more than
sixty (60) days apart.
.SH EXAMPLE CRON
.nf
# 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
.fi
