I don't remember anyone saying they couldn't be stored, just that if they are stored it's not ZFS' fault if they go corrupt as it's outside of its control. I'm actually planning to store the zfs send dump on external USB devices myself, but since the USB device will be running on ZFS I expect

However, I don't think that's what they're talking about here. I think they're talking about a ZFS pool that consists of an external USB device, and doing a send / receive directly to that pool. That way the USB device is a true backup copy of your ZFS pool, and I think the idea is that

Hi Miles, I probably should have explained that storing the zfs send on a USB device is just one part of the strategy, and in fact that's just our way of getting the backup off-site. Once off-site, we do zfs receive that into another pool, and in fact we plan to have two offsite zfs pools,

Hi Niall, I noticed that ZFS won't automatically import pools myself. I didn't really consider it a problem since I wanted to script a bunch of stuff on USB insertion. I was hoping to be able to write a script that would detect the insertion, attempt to automatically mount pools on devices

I believe the answer is in the last email in that thread. hald doesn't offer the notifications and it's not clear that ZFS can handle them. As is noted, there are complications with ZFS due to the possibility of multiple disks comprising a volume, etc. It would be a lot of work to make it work

Hey guys, This may be a dumb thought from an end user, but why does it have to be hard for ZFS to automatically mount volumes on removable media? Mounting single volumes should be straightforward and couldn't you just try to import any others and just silently fail if any required pieces are

Hi, As a part of the next stages of the time-slider project we are looking into doing actual backups onto removable media devices such as USB media. The goal is to be able to view snapshots stored on the media and merge these into the list of viewable snapshots in nautilus giving the user a
