Prior to doing the complete system backups (as outlined in my last email), I enter Firefox and clear all history.
why? it's not going to make that much difference in time taken or space consumed.
I don't know about Mozilla, but my Chrome cache is about 500M on the laptop I'm using now (which wouldn't rank higher than 3rd place for active web browsing systems I run). That makes a difference in space used.
500M isn't much these days. even 5GB is hardly noticable these days.
I think that Chrome isn't particularly good about managing the cache, for example I think that the cache file from last year is very unlikely to be of any use.
so run a cron job to clear it out every so often - checking to make sure chromium isn't running before deleting anything.
anyway, there's no need to delete before backing up, just tell rsync not to backup that directory.
Of course a decision to not backup files means that the application won't have access to them after a restore. So it's worth knowing what happens if you delete them. A quick test would be a good idea.
a cache is, by definition, transient, replaceable data. there should be no problem deleting it (or not backing up). if some program breaks because its cache is missing, then that's a bug that needs to be fixed. craig -- craig sanders <cas@taz.net.au>
