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. 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. 500M+ of rapidly changing data for each of 3 systems makes a real difference when I'm storing incremental backups on a 500G disk! One thing I've been planning to do is to create a separate BTRFS subvolume for ~/.cache, that would exclude it from the BTRFS snapshot backups as well as the removable media backups (which are from the snapshot backups). > > But, during the backup (after booting into Recovery mode), rsync > > displays the copying of MANY files within this directory... > > > > /home/user/.cache/mozilla/firefox/abcd1234.default/cache2/trash/3363925 > > > > Given the names of some of those directories, I wonder if it is safe > > to delete them (rm -r) just before the backup? > > > > If so, at which level... trash? cache2? > > 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. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
