Remember a given btrfs filesystem is not necessarily a backup destination for data from one source. It can be, say, 30 or 60 daily snapshots, plus several monthly, for each data source * number of data sources. So while it probably will make a difference (5000 snapshots from one source, vs 5000 snapshots made from many sources) for balance times, I wouldn't call a large number of snapshots that unusual. -- Tomasz Chmielewski http://www.sslrack.com
