# ZFS Uploader
ZFS Uploader is a simple program for backing up full and incremental ZFS
snapshots to Amazon S3. It supports CRON based scheduling and can
automatically remove old snapshots and backups. A helpful CLI (`zfsup`) lets
you run jobs, restore, and list backups.
### Features
- Backup/restore ZFS file systems
- Create incremental and full backups
- Automatically remove old snapshots and backups
- Use any S3 storage class type
- Helpful CLI
### Requirements
- Python 3.6 or higher
- ZFS 0.8.1 or higher (untested on earlier versions)
## Install Instructions
Commands should be run as root.
1. Create a directory and virtual environment
```bash
mkdir /etc/zfs_uploader
cd /etc/zfs_uploader
virtualenv --python python3 env
```
2. Install ZFS Uploader
```bash
source env/bin/activate
pip install zfs_uploader
ln -sf /etc/zfs_uploader/env/bin/zfsup /usr/local/sbin/zfsup
```
3. Write configuration file
Please see the [Configuration File](#configuration-file) section below for
helpful configuration examples.
```bash
vi config.cfg
chmod 600 config.cfg
```
4. Start service
```bash
cp zfs_uploader.service /etc/systemd/system/zfs_uploader.service
sudo systemctl enable --now zfs_uploader
```
5. List backups
```bash
zfsup list
```
## Configuration File
The program reads backup job parameters from a configuration file. Default
parameters may be set which then apply to all backup jobs. Multiple backup
jobs can be set in one file.
### Parameters
#### bucket_name : str
S3 bucket name.
#### access_key : str
S3 access key.
#### secret_key : str
S3 secret key.
#### filesystem : str
ZFS filesystem.
#### prefix : str, optional
Prefix to be prepended to the s3 key.
#### region : str, default: us-east-1
S3 region.
#### endpoint : str, optional
S3 endpoint for alternative services
#### cron : str, optional
Cron schedule. Example: `* 0 * * *`
#### max_snapshots : int, optional
Maximum number of snapshots.
#### max_backups : int, optional
Maximum number of full and incremental backups.
#### max_incremental_backups_per_full : int, optional
Maximum number of incremental backups per full backup.
#### storage_class : str, default: STANDARD
S3 storage class.
#### max_multipart_parts : int, default: 10000
Maximum number of parts to use in a multipart S3 upload.
### Examples
#### Multiple full backups
```ini
[DEFAULT]
bucket_name = BUCKET_NAME
region = us-east-1
access_key = ACCESS_KEY
secret_key = SECRET_KEY
storage_class = STANDARD
[pool/filesystem]
cron = 0 2 * * *
max_snapshots = 7
max_incremental_backups_per_full = 6
max_backups = 7
```
Filesystem is backed up at 02:00 daily. Only the most recent 7 snapshots
are kept. The oldest backup without dependents is removed once there are
more than 7 backups.
#### Backblaze B2 S3-compatible endpoint, full backups
```ini
[DEFAULT]
bucket_name = BUCKET_NAME
region = eu-central-003
access_key = ACCESS_KEY
secret_key = SECRET_KEY
storage_class = STANDARD
endpoint = https://s3.eu-central-003.backblazeb2.com
[pool/filesystem]
cron = 0 2 * * *
max_snapshots = 7
max_incremental_backups_per_full = 6
max_backups = 7
```

#### Single full backup
```ini
[DEFAULT]
bucket_name = BUCKET_NAME
region = us-east-1
access_key = ACCESS_KEY
secret_key = SECRET_KEY
storage_class = STANDARD
[pool/filesystem]
cron = 0 2 * * *
max_snapshots = 7
max_backups = 7
```
Filesystem is backed up at 02:00 daily. Only the most recent 7 snapshots
are kept. The oldest incremental backup is removed once there are
more than 7 backups. The full backup is never removed.

```
Filesystem is backed up at 02:00 daily. Only the most recent 7 snapshots
are kept. The oldest full backup is removed once there are
more than 7 backups. No incremental backups are taken.
