Using Time Slider

This appendix describes Time Slider as a tool for certain snapshot management tasks. The appendix covers the following topics:

About Time Slider

Time Slider provides a graphical way for Oracle Solaris desktop users to restore individual files or directories from automatically scheduled, incremental snapshots of home directories. If enabled, Time Slider takes a snapshot of every ZFS file system every 15 minutes, by default. These snapshots are then deleted again over time, such that only one snapshot is kept for each of the previous 24 hours, one for each of the previous 7 days, and one for each previous week that the Time Slider service was running.

Time Slider can automate periodic snapshots for any ZFS file system, including boot environments, even on non-desktop systems.


Note -  If you install the desktop/time-slider package, some desktop component dependencies might also be included in the installation.

Time Slider uses the following SMF services:

  • svc:/system/filesystem/zfs/auto-snapshot:frequent: Takes one snapshot every 15 minutes

  • svc:/system/filesystem/zfs/auto-snapshot:hourly: Takes one snapshot every hour

  • svc:/system/filesystem/zfs/auto-snapshot:daily: Takes one snapshot every day

  • svc:/system/filesystem/zfs/auto-snapshot:weekly: Takes one snapshot every week

  • svc:/system/filesystem/zfs/auto-snapshot:monthly: Takes one snapshot every month

  • svc:/application/time-slider:default: Manages automatic deletion of snapshots

  • svc:/application/time-slider/plugin:rsync: Replicates each snapshot automatically to a specified external storage device
