=====To Workstation=====
=====To Workstation=====
Backup to workstation provides for daily full or incremental backup on LAN workstation (via nfs or cifs) or local usb disk, and full or selective restore with use of dar program.
The main features of backup with dar aside use of session timeout are:
Incremental backup. This means that you can backup and restore data for the period of time you want : one day, three days, one week, one month, 100 days... and restore your system at any state it was during this period of time. This probably has no utility to do full restore of the system as it was one month ago, but restoring a file lost by a user two or three weeks ago can be useful. And restoring a safe system more than one day old can be needed.
The second function is keeping more than one set of backup (a set is full backup data and all data of next daily incremental backups) with automatic rotation. e.g. you can do only nightly full backups but keep three sets of backup for security reason (as being able to restore the system as it was 72h ago).
The third function is selective restore of any saved file or directory, exactly as it was for any of the saved days in your sets. Not only you can restore a lost file at it's last state, but also say : make restore of the most recent version of the file before this given date... Selective restore is not an easy thing to manage by hand, and providing this in a simple way with panels is useful. Dar permits to manage selective restore and e-smith-backup with dar panels tries to keep this function as simple as possible to use.

Change these to suit your particular situation.
In a typical scenario with Windows workstations backing up to a removable or shared drive in a workstation, with a weekly full backup on Friday and subsequent daily incremental backups & you wish to retain 2 backup sets on each disk, with backup to start at 8pm and finish at 8am, use the following settings.
Backup is enabled.
Backup is made on LAN workstation netshare via cifs
Destination backup share folder is backup
Login is backupuser
Password is ********
Number of rotating backup sets is 2
Number of daily backups contained in each set is 7
Compression level (0-7) of backup is 4
Daily backup occurs at 20:00
Each daily backup session is cleanly timed out after 12h except full backups which are cleanly timed out after 24 hours
Full backup session (new backup sets) is allowed only on Friday
======Verify workstation backup======
======Verify workstation backup======
This option allows you to verify that the backup to disk was completed successfully. In rare cases we have found that users ran out of disk space on their client PC while doing the backup to desktop. This options allows you to verify whether or not the backup did in fact complete successfully.
