* Complete rewrite, cleaner object oriented code.

* Python 3 and 2 support.

* Automated regression against real ZFS environment.

* Installable via [pip](https://pypi.org/project/zfs-autobackup/).
|
||||
* Backwards compatible with your current backups and parameters.
|
||||
* Progressive thinning (via a destroy schedule. default schedule should be fine for most people)

This is a tool I wrote to make replicating ZFS datasets easy and reliable.

You can either use it as a **backup** tool, **replication** tool or **snapshot** tool.
|

|

You can select what to backup by setting a custom `ZFS property`. This allows you to set and forget: Configure it so it backups your entire pool, and you never have to worry about backupping again. Even new datasets you create later will be backupped.

An important feature thats missing from other tools is a reliable `--test` option: This allows you to see what zfs-autobackup will do and tune your parameters. It will do everything, except make changes to your zfs datasets.

Another nice thing is progress reporting with `--progress`. Its very useful with HUGE datasets, when you want to know how many hours/days it will take.

* Checks everything but tries continue on non-fatal errors when possible. (Reports error-count when done)
|

* Ability to 'finish' aborted backups to see what goes wrong.
|
||||
* Ability to manually 'finish' failed backups to see whats going on.
|
||||
* Easy to debug and has a test-mode. Actual unix commands are printed.
|
||||
* Keeps latest X snapshots remote and locally. (default 30, configurable)
|
||||
* Uses **progressive thinning** for older snapshots.
|
||||
* Uses zfs-holds on important snapshots so they cant be accidentally destroyed.
|
||||
* Automatic resuming of failed transfers.
|
||||
* Can continue from existing common snapshots. (e.g. easy migration)
|
||||
* Gracefully handles destroyed datasets on source.

* Easy installation:
|

* Just install zfs-autobackup via pip, or download it manually.

* Written in python and uses zfs-commands, no 3rd party dependency's or libraries.

### Destroying missing datasets
|
||||
|
||||
When a dataset has been destroyed or deselected on the source, but still exists on the target we call it a missing dataset. Missing datasets will be still thinned out according to the schedule.
|
||||
|
||||
The final snapshot will never be destroyed, unless you specify a **deadline** with the `--destroy-missing` option:
|
||||
|
||||
In that case it will look at the last snapshot we took and determine if is older than the deadline you specified. e.g: `--destroy-missing 30d` will start destroying things 30 days after the last snapshot.
|
||||
|
||||
#### After the deadline
|
||||
|
||||
When the deadline is passed, all our snapshots, except the last one will be destroyed. Irregardless of the normal thinning schedule.
|
||||
|
||||
The dataset has to have the following properties to be finally really destroyed:
|
||||
|
||||
* The dataset has no direct child-filesystems or volumes.
|
||||
* The only snapshot left is the last one created by zfs-autobackup.
|
||||
* The remaining snapshot has no clones.

## Tips
|
||||
|
||||
* Use ```--debug``` if something goes wrong and you want to see the commands that are executed. This will also stop at the first error.
|
||||
* You can split up the snapshotting and sending tasks by creating two cronjobs. Use ```--no-send``` for the snapshotter-cronjob and use ```--no-snapshot``` for the send-cronjob. This is usefull if you only want to send at night or if your send take too long.
|
||||
* You can split up the snapshotting and sending tasks by creating two cronjobs. Create a separate snapshotter-cronjob by just omitting target-path.
|
||||
* Set the ```readonly``` property of the target filesystem to ```on```. This prevents changes on the target side. (Normally, if there are changes the next backup will fail and will require a zfs rollback.) Note that readonly means you cant change the CONTENTS of the dataset directly. Its still possible to receive new datasets and manipulate properties etc.
|
||||
* Use ```--clear-refreservation``` to save space on your backup server.
|
||||
* Use ```--clear-mountpoint``` to prevent the target server from mounting the backupped filesystem in the wrong place during a reboot.
|
||||
* Use ```--resume``` to be able to resume aborted backups. (not all zfs versions support this)

## Backuping up a proxmox cluster with HA replication
|
||||
## Backup a proxmox cluster with HA replication
|
||||
|
||||
Due to the nature of proxmox we had to make a few enhancements to zfs-autobackup. This will probably also benefit other systems that use their own replication in combination with zfs-autobackup.
|
||||
|
||||
All data under rpool/data can be on multiple nodes of the cluster. The naming of those filesystem is unique over the whole cluster. Because of this we should backup rpool/data of all nodes to the same destination. This way we wont have duplicate backups of the filesystems that are replicated. Because of various options, you can even migrate hosts and zfs-autobackup will be fine. (and it will get the next backup from the new node automatically)
|
||||
|
||||
In the example below we have 3 nodes, named h4, h5 and h6.
|
||||
|
||||
The backup will go to a machine named smartos03.
|
||||
In the example below we have 3 nodes, named pve1, pve2 and pve3.
|
||||
|
||||
### Preparing the proxmox nodes
|
||||
|
||||
On each node select the filesystems as following:
|
||||
No preparation is needed, the script will take care of everything. You only need to setup the ssh keys, so that the backup server can access the proxmox server.
|
||||
|
||||
```console
|
||||
root@h4:~# zfs set autobackup:h4_smartos03=true rpool
|
||||
root@h4:~# zfs set autobackup:h4_smartos03=false rpool/data
|
||||
root@h4:~# zfs set autobackup:data_smartos03=child rpool/data
|
||||
TIP: make sure your backup server is firewalled and cannot be reached from any production machine.
|
||||
|
||||
### SSH config on backup server
|
||||
|
||||
I use ~/.ssh/config to specify how to reach the various hosts.
|
||||
|
||||
In this example we are making an offsite copy and use portforwarding to reach the proxmox machines:
|
||||
```
|
||||
Host *
|
||||
ControlPath ~/.ssh/control-master-%r@%h:%p
|
||||
ControlMaster auto
|
||||
ControlPersist 3600
|
||||
Compression yes
|
||||
|
||||
Host pve1
|
||||
Hostname some.host.com
|
||||

|
||||
|
||||
Host pve2
|
||||
Hostname some.host.com
|
||||
Port 10002
|
||||
|
||||
Host pve3
|
||||
Hostname some.host.com
|
||||
Port 10003
|
||||
```
|
||||
|
||||
* rpool will be backuped the usual way, and is named h4_smartos03. (each node will have a unique name)
|
||||
* rpool/data will be excluded from the usual backup
|
||||
* The CHILDREN of rpool/data be selected for a cluster wide backup named data_smartos03. (each node uses the same backup name)
|
||||
### Backup script
|
||||
|
||||
### Preparing the backup server
|
||||
I use the following backup script on the backup server.
|
||||
|
||||
Extra options needed for proxmox with HA:
|
||||
|
||||
* --no-holds: To allow proxmox to destroy our snapshots if a VM migrates to another node.
|
||||
* --ignore-replicated: To ignore the replicated filesystems of proxmox on the receiving proxmox nodes. (e.g: only backup from the node where the VM is active)
|
||||
* --min-change 200000: Ignore replicated works by checking if there are no changes since the last snapshot. However for some reason proxmox always has some small changes. (Probably house-keeping data are something? This always was fine and suddenly changed with an update)
|
||||

||||

|
||||
