Hi, I have a very limited amount of bandwidth between main office and
a colocated rack of servers in a managed datacenter. My hope is to be
able to zfs send/recv small incremental changes on a nightly basis as
a secondary offsite backup strategy. My question is about the initial
"seed" of the data. Is it possible to use a portable drive to copy the
initial zfs filesystem(s) to the remote location and then make the
subsequent incrementals over the network? If so, what would I need to
do to make sure it is an exact copy? Thank you,
Mark
Just be aware that sending zfs snapshots not only involves the actual
new data, that has been written to the source(s) but also the metadata.
If you don't need it, maybe disableing atime will take away some of that
load, but I have learned that, depending on how the dataset gets
accessed - in my case it's all about file sharing via netatalk and
samba, the stream resulting from an incremental zfs send as always
significantly greater than the data, that has been altered or has been
written newly onto the dataset.
