SYNCOID
|
||||
-------
|
||||
Syncoid depends on ssh, pv, gzip, lzop, and mbuffer. It can run with reduced
|
||||
functionality in the absence of any or all of the above. SSH is only required
|
||||
for remote synchronization. On newer FreeBSD and Ubuntu Xenial
|
||||
chacha20-poly1305@openssh.com, on other distributions arcfour crypto is the
|
||||
default for SSH transport since v1.4.6. Syncoid runs will fail if one of them
|
||||
is not available on either end of the transport.
|
||||
|
||||
On Ubuntu: apt install pv lzop mbuffer
|
||||
On CentOS: yum install lzo pv mbuffer lzop perl-Data-Dumper
|
||||
On FreeBSD: pkg install pv mbuffer lzop
|
||||
|
||||
FreeBSD notes: FreeBSD may place pv and lzop in somewhere other than
|
||||
/usr/bin ; syncoid currently does not check path.
|
||||
|
||||
Simplest path workaround is symlinks, eg:
|
||||
root@bsd:~# ln -s /usr/local/bin/lzop /usr/bin/lzop
|
||||
or similar, as appropriate, to create links in /usr/bin
|
||||
to wherever the utilities actually are on your system.
|
||||
|
||||
See note about mbuffer in FREEBSD.readme
|
||||
|
||||
|
||||
SANOID
|
||||
------
|
||||
Sanoid depends on the Perl module Config::IniFiles and will not operate
|
||||
without it. Config::IniFiles may be installed from CPAN, though the project
|
||||
strongly recommends using your distribution's repositories instead.
|
||||
|
||||
On Ubuntu: apt install libconfig-inifiles-perl
|
||||
On CentOS: yum install perl-Config-IniFiles
|
||||
On FreeBSD: pkg install p5-Config-IniFiles

# Installation
|
||||
|
||||
**Sanoid** and **Syncoid** are complementary but separate pieces of software. To install and configure them, follow the guide below for your operating system. Everything in `code blocks` should be copy-pasteable. If your OS isn't listed, a set of general instructions is at the end of the list and you can perform the process manually.

|
||||
|
||||
|
||||
## Debian/Ubuntu
|
||||
|
||||
Install prerequisite software:
|
||||
|
||||
```bash
|
||||
apt install libconfig-inifiles-perl pv lzop mbuffer
|
||||
```
|
||||
|
||||
Clone this repo, build the debian package and install it (alternatively you can skip the package and do it manually like described below for CentOS):
|
||||
|
||||
```bash
|
||||
# Download the repo as root to avoid changing permissions later
|
||||
sudo git clone https://github.com/jimsalterjrs/sanoid.git
|
||||
cd sanoid
|
||||
ln -s packages/debian .
|
||||
dpkg-buildpackage -uc -us
|
||||
apt install ../sanoid_*_all.deb
|
||||
```
|
||||
|
||||
Enable sanoid timer:
|
||||
```bash
|
||||
# enable and start the sanoid timer
|
||||
sudo systemctl enable sanoid.timer
|
||||
sudo systemctl start sanoid.timer
|
||||
```
|
||||
|
||||
## CentOS
|
||||
|
||||
Install prerequisite software:
|
||||
|
||||
```bash
|
||||
# Install and enable epel if we don't already have it, and git too
|
||||
sudo yum install -y epel-release git
|
||||
# Install the packages that Sanoid depends on:
|
||||
sudo yum install -y perl-Config-IniFiles perl-Data-Dumper lzop mbuffer mhash pv
|
||||
```
|
||||
|
||||
Clone this repo, then put the executables and config files into the appropriate directories:
|
||||
|
||||
```bash
|
||||
# Download the repo as root to avoid changing permissions later
|
||||
sudo git clone https://github.com/jimsalterjrs/sanoid.git
|
||||
cd sanoid
|
||||
# Install the executables
|
||||
sudo cp sanoid syncoid findoid sleepymutex /usr/local/sbin
|
||||
# Create the config directory
|
||||
sudo mkdir /etc/sanoid
|
||||
# Install default config
|
||||
sudo cp sanoid.defaults.conf /etc/sanoid
|
||||
# Create a blank config file
|
||||
sudo touch /etc/sanoid/sanoid.conf
|
||||
# Place the sample config in the conf directory for reference
|
||||
sudo cp sanoid.conf /etc/sanoid/sanoid.example.conf
|
||||
```
|
||||
|
||||
Create a systemd service:
|
||||
|
||||
```bash
|
||||
cat << "EOF" | sudo tee /etc/systemd/system/sanoid.service
|
||||
[Unit]
|
||||
Description=Snapshot ZFS Pool
|
||||
Requires=zfs.target
|
||||
After=zfs.target
|
||||
ConditionFileNotEmpty=/etc/sanoid/sanoid.conf
|
||||
|
||||
[Service]
|
||||
Environment=TZ=UTC
|
||||

|
||||
ExecStart=/usr/local/sbin/sanoid --take-snapshots --verbose
|
||||

|
||||
|
||||

|

||||
|
||||

|
||||
Environment=TZ=UTC
|
||||
Type=oneshot
|
||||
ExecStart=/usr/local/sbin/sanoid --prune-snapshots --verbose
|
||||
|
||||
[Install]
|
||||
WantedBy=sanoid.service
|
||||
EOF
|
||||
```
|
||||
|
||||
And a systemd timer that will execute **Sanoid** once per quarter hour
|
||||
(Decrease the interval as suitable for configuration):
|
||||
|
||||
```bash
|
||||
cat << "EOF" | sudo tee /etc/systemd/system/sanoid.timer
|
||||
[Unit]
|
||||
Description=Run Sanoid Every 15 Minutes
|
||||
Requires=sanoid.service
|
||||
|
||||
[Timer]
|
||||
OnCalendar=*:0/15
|
||||
Persistent=true
|
||||
|
||||
[Install]
|
||||
WantedBy=timers.target
|
||||
EOF
|
||||
```
|
||||
|
||||
Reload systemd and start our timer:
|
||||
```bash
|
||||
# Tell systemd about our new service definitions
|
||||
sudo systemctl daemon-reload
|
||||
# Enable and start the Sanoid timer
|
||||
sudo systemctl enable sanoid.timer
|
||||
sudo systemctl start sanoid.timer
|
||||
```
|
||||
|
||||
Now, proceed to configure [**Sanoid**](#configuration)
|
||||
|
||||
## FreeBSD
|
||||
|
||||
Install prerequisite software:
|
||||
|
||||
```bash
|
||||
pkg install p5-Config-Inifiles pv mbuffer lzop
|
||||
```
|
||||
|
||||
**Additional notes:**
|
||||
|
||||
* FreeBSD may place pv and lzop in somewhere other than /usr/bin — syncoid currently does not check path.
|
||||
|
||||
* Simplest path workaround is symlinks, eg `ln -s /usr/local/bin/lzop /usr/bin/lzop` or similar, as appropriate to create links in **/usr/bin** to wherever the utilities actually are on your system.
|
||||
|
||||
* See note about mbuffer and other things in FREEBSD.readme
|
||||
|
||||

|
||||
|
||||
**Sanoid** depends on the Perl module Config::IniFiles and will not operate without it. Config::IniFiles may be installed from CPAN, though the project strongly recommends using your distribution's repositories instead.
|
||||

Syncoid runs will fail if one of them is not available on either end of the transport.
|
||||
|
||||
### General outline for installation
|
||||
|
||||
1. Install prerequisites: Perl module Config::IniFiles, ssh, pv, gzip, lzop, and mbuffer
|
||||
2. Download the **Sanoid** repo
|
||||
3. Create the config directory `/etc/sanoid` and put `sanoid.defaults.conf` in there, and create `sanoid.conf` in it too
|
||||
4. Create a cron job or a systemd timer that runs `sanoid --cron` once per minute
|
||||
|
||||
# Configuration
|
||||
|
||||
**Sanoid** won't do anything useful unless you tell it how to handle your ZFS datasets in `/etc/sanoid/sanoid.conf`.
|
||||
|
||||
**Syncoid** is a command line utility that doesn't require any configuration, with all of its switches set at runtime.
|
||||
|
||||
## Sanoid
|
||||
|
||||
Take a look at the files `sanoid.defaults.conf` and` sanoid.conf.example` for all possible configuration options. Also have a look at the README.md

This argument tells syncoid to restrict itself to existing snapshots, instead of creating a semi-ephemeral syncoid snapshot at execution time. Especially useful in multi-target (A->B, A->C) replication schemes, where you might otherwise accumulate a large number of foreign syncoid snapshots.
|

|

+ --create-bookmark
|
||||
|
||||
This argument tells syncoid to create a zfs bookmark for the newest snapshot after it got replicated successfully. The bookmark name will be equal to the snapshot name. Only works in combination with the --no-sync-snap option. This can be very useful for irregular replication where the last matching snapshot on the source was already deleted but the bookmark remains so a replication is still possible.

--skip-parent Skips syncing of the parent dataset. Does nothing without '--recursive' option.

--mbuffer-size=VALUE Specify the mbuffer size (default: 16M), please refer to mbuffer(1) manual page.
|

--no-stream Replicates using newest snapshot instead of intermediates
|
||||
--no-sync-snap Does not create new snapshot, only transfers existing
|

--create-bookmark Creates a zfs bookmark for the newest snapshot on the source after replication succeeds (only works with --no-sync-snap)
|

--no-clone-rollback Does not rollback clones on target
|

--no-rollback Does not rollback clones or snapshots on target (it probably requires a readonly target)
