I would like some input about the use of zfs snapshot. The Auto snapshot is nice on rpool but in some of the other zfs fs I've created that kind of frequency doesn't seem necessary.
However generating my own cron setup for a dozen or so fs to create snapshots, maybe only when data is transferred, in will take a fair bit of scripting, thought and time to get done and working smoothly... It would need scripting that was easily expanded as more fs are needed. I'm capable of the scripting but it would take me a fair while to get that all working smoothly. Its tempting to just let the auto snapshot stuff run on all fs. I guess what I'm asking about is if that number of snapshots will be a serious problem at some future time... Most of my zfs fs are devoted to accumulating data from remote windows and linux desktops. All of the current FS reside on mirrored pools.. not raid. Just pairs of matched discs in mirror mode. Two 750s' and 4 500s' in 3 sets of paired mirrors. I'm not going to need more any time soon since this is a small home lan that the zfs server handles. It seems to me, it would suffice to create snapshots whenever more data is transferred in. In between, isn't the data fairly safe since its mirrored and not much goes on in the fs unless a file is needed on one of the desktops (and then it wouldn't be much traffic)? But some kind of scheme like that would take some doing as noted already. Are there existing scripts for handling snapshots in some other fashion than the auto setup? Is it even necessary to worry about it? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
