The best choice is to rename the syslog files with a date, and don't repeatedly rename them, eg: syslog.YYYYMMDD.gz (eg: syslog.20021128.gz). Pruning old ones isn't too hard: simply reverse sort the names and remove everything after the first 213. It also makes it easier to find a particular log file. > 2) create hard-links to identical files in > --backup-dir=/backup/incremental-2002-11-27 when is detects that > /server/sylog.138.gz is the actually the same as > /backup/current/syslog.137.gz, BackupPC is one package that does this; see http://backuppc.sourceforge.net. (disclaimer: I'm the author). I'm in the process of adding rsync support.
