Hi,

is there a way not to replicate houry and frequent snapshots between dailys?
I removed the -R at zfs send, but it seems it still does ist!

Cheers

Hi Guys,

perhaps you are able to add a kind of compression to the Replication, similar FreeNAS does it.

Perhaps you can Pipe the zfs send and recive via a gzip or lz4?

We do not use compression on Datasets and ZVOLs because of using VMs and latency!

This would multiply the load of Data, especially on WAN Connections.

For local Speedup perhaps you can add mbuffer?

I really appreciate your great work!
If there is a way to donate, let me know!

Having the following pool layout:

tank
tank/a
tank/a/b
tank/c
...

all of the filesystems are handled well, due to -e/-d FS=${DATASET#/} and FS_BASE=${DATASET##/}
However, this doesn't work for the very pool root (not sure what the official name for it is).

"tank" doesn't match neither FS nor FS_BASE and will result in the following remote layout:
remote/tank
remote/a
remote/a/b
remote/c
...

the goal is to make sure local "tank" (pool root) can sync into "remote" (remote pool root).

I used the following code to provide special case handling for pool root, right after -e/-d case handling (

# Special case for pool root
if [[ "$DATASET" != */* ]]
then
  TARGET="$REMPOOL"
fi

please add this special case into your repo.

Hi, please provide a function to keep snapshots longer on destination!

hi,
please explain (step by step) how to set the $PROP value in script for files-1tb/jails because I'm misunderstand something:

Filesystem 1K-blocks Used Avail Capacity Mounted on

files-1tb/jails 823983904 128 823983776 0% /files-1tb/jails

Thank you.

hi .. im try a script for backup snapshot to another server using zfs. but i have error like this

No datasets configured for backup! Please set the 'com.edu:backuptarget' property
appropriately on the datasets you wish to back up.

what the meaning "com.edu:backuptarget" ?

if i see a command "zfs get datapool/fs1"
im not see property "com.edu:backuptarget"

and if im add manual will be error no value property.

anyone can help ? or give me any reference ?

thanks :)

Please add a flag to Filter like -r but with creation value

When I run the script without the -v-Option, there's no output -- when I use -v I get this:
`./zfs-backup.sh -v

rpool/vm-199-disk-0:
./zfs-backup.sh[195]: [: argument expected
./zfs-backup.sh[213]: [: argument expected
Remote snapshot is the same as local; not running.
`
What's wrong?
