Just added a new section to /etc/periodic/monthly/mine.monthly
in the attempt to create monthly backups of my subversion repositories, using compressed dump files:
[Update: Now using quoted variable names.]
[Update: Now checking "format" file.]
if [ -d /Library/Repositories ]; then
cd /Library/Repositories
for i in * ; do
# Not a subversion repository? Ignore it.
if [ ! -f "$i/format" ]; then
continue
fi
line="/tmp/monthly-$i.out"
# File: /Volumes/Backups/Attic/svn-file-2014-01-17.dump.gz
name="svn-$i-`date +%F`.dump.gz"
dump="/Volumes/Backups/Attic/$name"
if [ ! -f "$dump" ]; then
echo "Dumping subversion repository: $name"
# Dump into a gzipped file; "Dumped revision n" into temp file.
{ /usr/bin/svnadmin dump "$i" | gzip -c -9 > "$dump"; } >& "$line"
# Change the user for the dump file.
chown gollum:gollum "$dump"
# Only output the last stderr line then delete the file.
tail -1 "$line"
rm "$line"
else
echo "Warning: Dump already exists: $name"
fi
done
else
echo "Error: Repositories directory not found."
fi
N.B. I also use TrashLater to keep files for only 6 months in the Attic folder.
For /etc/periodic/weekly/mine.weekly
I only dump the most recently modified repository since I don't normally work on multiple projects. This is done with a different foreach loop, where we get just one repository file name:
if [ -d /Library/Repositories ]; then
cd /Library/Repositories
# List the dir by last modified and get the first entry only.
for i in `ls -1t | sed '1 q'` ; do
line="/tmp/weekly-$i.out"
# [...as above...]
done
else
echo "Error: Subversion repositories not found."
fi
