DESCRIPTION
|
||||
|

This is a *prototype* of a simple SMF service which you can configure to
|
||||
take automatic, scheduled snapshots of any given ZFS filesystem as well
|
||||
as perform simple incremental or full backups of that filesystem.

|
||||
|
||||
To use the service, the user must install the method script, import the default
|
||||
instance, and then create instances for each ZFS filesystem that should be
|
||||
managed by the service.

Documentation for the service instance is contained in the manifest file,

|
||||
|
||||
As of version 0.9 there is a simple GUI that allows the user to configure
|
||||
which filesystems are to be included in the default canned SMF instances.
|
||||
This GUI is installed in the GNOME menu under:
|
||||
|
||||
Administration -> Automatic Snapshots
|
||||
|
||||
We also bundle a simple GUI application, which will query the user for the
|
||||
properties required, and will proceed to build an instance manifest. This
|
||||
GUI is documented as part of the installation instructions below.

INSTALLATION
|

|
||||
To install, as root, run the following commands:
|
||||
To install, as root, pkgadd TIMFauto-snapshot. This package now contains
|
||||
several canned SMF instances which are enabled by default. These are:
|
||||
|
||||
# cp zfs-auto-snapshot/lib/svc/method/zfs-auto-snapshot /lib/svc/method
|
||||
# svccfg import zfs-auto-snapshot/zfs-auto-snapshot.xml
|
||||
online 1:17:43 svc:/system/filesystem/zfs/auto-snapshot:hourly
|
||||

|
||||
online 1:17:49 svc:/system/filesystem/zfs/auto-snapshot:weekly
|
||||
|
||||
Once you have installed these, you need to create an instance of the service
|
||||
for each set of ZFS snapshots you want to take. The properties we need are:
|
||||
These instances use the special "//" fs-name to determine which filesystems
|
||||
should be included in each snapshot schedule. See the description for "fs-name"
|
||||
below.
|
||||
|
||||
zfs/fs-name The name of the filesystem
|
||||
The included instances have the following properties:
|
||||
|
||||
frequent snapshots every 15 mins, keeping 4 snapshots
|
||||
hourly snapshots every hour, keeping 24 snapshots
|
||||
daily snapshots every day, keeping 31 snapshots
|
||||
weekly snapshots every week, keeping 7 snapshots
|
||||
monthly snapshots every month, keeping 12 snapshots
|
||||
|
||||
The default service instance does not need to be enabled.
|
||||
|
||||
Additional instances of the service can also be created, for example to group
|
||||
related sets of filesystems under a single service instance.
|
||||
|
||||
The properties each instance needs are:
|
||||
|
||||
zfs/fs-name The name of the filesystem. If the special filesystem
|
||||
name "//" is used, then the system snapshots all
|
||||
filesystems with the zfs user property
|
||||
"com.sun:auto-snapshot:<label>" set to true, so to take
|
||||
frequent snapshots of tank/timf, run the following zfs
|
||||
command:
|
||||
|
||||
# zfs set com.sun:auto-snapshot:frequent=true tank/timf

zfs/label A label that can be used to differentiate this set of

backups from others, not required.

|

zfs/verbose Set to false by default, setting to true makes the

service produce more output about what it's doing.

zfs/avoidscrub Set to true by default, this determines whether
