zxfer doesn't transfer zfs data sets that have no snapshots #50

Open eohrnberger opened 5 years ago

eohrnberger commented 5 years ago

Hi, Love zxfer, and have cron jobs that transfer data sets from primary storage to backup storage, and it works very well.

I had a zfs dataset that didn't have any snapshots and wanted to transfer that dataset to backups. No problem, use zxfer. Except it didn't.

I added a single snapshot to the source dataset, and then all was well.

But I wonder if this capability in zxfer might be included in future release.

Also, could the manpage be updated to remove http://www.zxfer.org and replace it with https://github.com/allanjude/zxfer?

In ZFS it is not possible to replicate without a snapshot. zxfer does not create snapshots.

Yes, that is a good idea.

Yeah, then this is not possible, but thought that I'd ask.

I just ran into the same issue. The dataset was a canmount=off dataset, so there has never been any need to snapshot it.

Would it be a solution to let zxfer create the dataset instead of transferring, using the same properties it'd have used if it was sent?
