For starters, I suppose very few people are using FreeBSD on AWS, so "most of us" don't have a choice :-) But this might simply be my understanding: what if I want to use the EBS snapshot of the 5 disks I've taken and attach them to another machine, and mount it? But perhaps you don't know what an EBS snapshot is? It's not a backup of your file system, it's a hardware-based backup of a disk at a single point in time. I.e. with EBS I can take a snapshot of 5 1TB, create new disks from it, and attach it to another machine. In SECONDS. I'm not looking for a way to take a ZFS snapshot, stream that to S3 for hours, and stream it back and write to another disk for hours. But in case I didn't get you: could you please let me know if your approach would allow me to take a consistent backup of my disks and mount them on another server or use them for recovery purposes? --=20 All the best, Berend de Boer ------------------------------------------------------ Awesome Drupal hosting: https://www.xplainhosting.com/ --pgp-sign-Multipart_Wed_Jul__3_14:08:13_2013-1 Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit Content-Description: OpenPGP Digital Signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) iQIcBAABCAAGBQJR04eNAAoJEKOfeD48G3g5IJ0QAJq76UAFXIY5wHMOKjyUwKqH BO6kWfogMZmJloYYP6ckGdOwCmIwGJnFwIoxjKASIKTmw6WpXmkuZnEQpqKvKudk rBlPVa5hw8mcr2a2qvZqW2M6dsMH5abAfYyF7wGf/ktKME/RBIJhKi/kKpQMUAwc SqgZWoMS7Ye3wAf9MSfvpOXO553A1gb+7Bj6RbwSYeVsJahDyNd843JogRQ+g3ix SStvsTbmH+ppVLYDsrFhJQ2YD+Apk7aVGQ4JwkH5JQ+GWfq+gzz4E8W8SIfjKhF7 m6TWs73JzHAWL2OwA1GCxzv+ujdXnpdbESUp2oRHHNRf1a3hek+mUK7xldjUT+NN 4J2Lk+EE9P7XslG6pD4h8oHT5UPec6yvp9be+P4zh9Ut94X3EDeqL8PHjXlviubP iXLWW4AxRyfVxNOggs7XCn9oXFFmIbk5rnebgV7rdYfLIZnQ/mSuF2INBzAi7ROX qucJz53fF91gmTbN5iWxdaF+b0zgHnQGqP352OINz1Is7mJJn/F42uM7v8kwEgn+ sCNu3y603fV64ZsXuCXkGQxJV8KcFntzTOVa+sCzEKThMzRQFRo4es6B9e5sCTvi VAqlHs/OfZ6T94SVmQbOEoA91oYNLnS4qxc3fUbnvaMkolgs3Bj8q94Pavm56ygU q9t9Rgv5qUk/IEFAurZF =T6f7 -----END PGP SIGNATURE----- --pgp-sign-Multipart_Wed_Jul__3_14:08:13_2013-1--
