Schedules

Zeitpläne 4.0 en.jpg

This window shows an overview of the configured schedules and the events that are connected to them. Using the buttons in the toolbar you can configure the chronology of all processes in SEP sesam. Either create a new schedule or edit an existing one. In this schedule create a new event and define its job. The job is then done at the desired time and, if needed, forwarded to the next time of execution in the calendar.

Schedule properties - create new schedule

Name 
Name of the schedule
Execution 
(De-)Activate all events that are connected to this schedule
Cycle 
Options for cyclical behaviout of a schedule
once 
No repetition, single run
daily 
Repetition in days, hours or minutes
weekly
Repetition in weeks or weekdays
monthly 
Repetition on absolute or relative dates: 1st, 2nd, 3rd, 4th, last day, weekday, weekendday, Mon, Tue, Wed, Thu, Fri, Sat, Sun of the month. Optionally a positive and negative day offset is possible.
yearly 
Same as monthly; absolute and relative dates are possible
user specified (Option)
List of absolute and relative dates
Period of validity 
Range of time for the execution of a schedule. The date can be entered with a graphical calendar which pops up when clicked.
Begin 
Start time of the repetition cycle. The schedule is only valid after the day that's enterd in this field. There can be no execution prior to this date.
End 
If the checkbox next to End is selected the schedule will not be executed after the date that's specified in the field. If this field isn't activated the schedule is repeated indefinitely
Start time frame
the event can only be started within this defined time frame
Start 
Designated start time of the event. The actual start time depends on the processor load of the system. Every event is forwarded into the queue at its starting time. Depending on the workload and job limit of this queue and the schedule priority the execution has to wait until jobs with higher priority are finished. For jobs with the same priority there is the FIFO rule (first in first out).
Duration 
The user can define a start time frame by setting its duration. If the execution isn't possible within this time frame the job isn' started. This is entered in days, months, and minutes.


New Backup Event

The button 'New Backup Event opens the following window:

Restore Task 
Selection of a restore task
fix Restore 
When selecting Fix Restore the restore is executed exactly as defined in the task. The selected saveset is restored according to the set criteria and the selected files.
Selection
The restore task is used as a template. This way the backup task and the restore type (full, selective) are preset. The exact saveset however is selected dynamically by using the following entries.
Parameters 
Saveset Limitation 
indication of the time frame:
  • Sicht: ältester Auswahl: erster, zweiter, dritter, #-ter

backup day 
set a time frame for the backup day: from date ... to date
relative backup day

Example : 2 weeks ago until now: from date = -14, to date = 0
FDI-Type 
Only savesets with the according FDI-Type are selected (Copy, Full, Diff, Inc):C, F, D, I.
Selection 
A dynamic selection of the according saveset is done for the restore. Using the options youngest or oldest the youngest or oldest saveset within the selected time frame (as per the relative backup day and other limitations).
Media Preference 
Option to limit the media that are used as the restore source (should cloned media be used?)
  • No limitation >> ' '
  • Regular medium before clone >> 'media'
  • Clone before regular medium >> 'clone'. If no clone is available this selection is ignored.
Tolerance 
Option to limit the media that are used for the restore
  • Error if medium is not available (Default) >>
  • Only select available media >> 'available'
  • Only select available media that are eol-protected >> 'eol-protected'
Pool Restriction 
Option to limit the possble sources to specific media pools in a selection box.
Status 
Possible limitations in regard to the backup result are:
  • Successful or with warnings (Default)
  • Only successful
  • Only with warnings
  • partially restorable (canceled backups)

Drive Group 
Display of the drive group that's assigned to the selected media pool.
Drive 
Selection of the target drive that's to be used. Only drives that are assigned to the drive group are selectable.

Migration Task Event

New Migration Task Event

As with executing the other SEP sesam tasks first you need to create a new schedule in Scheduling -> Schedules.

Then, create a new migration task event in this schedule by clicking New Migration Task Event. Select the desired migration task from the drop-down-menu in the field Name and click OK.

Selection 
Instead of the saveset selected in the restore task a dynamic selection of the saveset to be restored from the time of the restore is made. Selections are newest or oldest', i.e. the newest/oldest saveset out of the selected interval (according to the relative backup day) is selected.
Media Preference 
Limiting selection of the media to use as the restore source / Should a cloned medium be used
  • No limitation >> ' '
  • Regular medium before clone >> 'media'
  • Clone before regular medium >> 'clone'

If no clone is available the selection is ignored.

  • Errors if media not available (Default) >>
  • Selection of available media >> 'available'
  • Selection of available media with EOL-block only >> 'eol-protected'
Pool Limitation 
Enables the backup source to be limited to specific mediapools by selecting a check box.

New Media Event

Newmediaevent 4.0 en.jpg


Succession Parameters
Priority
Priority
Blocking event
The event is only in effect to block other media events for the pool when schedules overlap


Execution Parameters
Media Pool
Grouping of media by certain criteria (e.g. by types of media etc.)
Media Strategy
Indication of strategy OLD defined in the media pool
Drive Group
Selection of a drive group. Advantage: Sesam uses the drives belonging to a specific group independently
Drive
Selection of a certain drive
Tape Label
Selection of a pre-set tape label (tape identification) from the media pool
Spare Label
Selection of a pre-set spare label from the media pool

A media event from the point of its activation defines a specific media of a pool onto which the backups write their data. The contents of the media are deleted by the event.

If the expected media is unavailable at the start of a backup or end of media is reached during data-transfer then SEP sesam creates an internal media event which provides the next media for the backup. If no media event is configured in the calendar only the internal one is in effect at the EOM.

New Command Event

The switch New Command Event opens following window:

Access restriction of command events

An event starts any executable command on the chosen client. Since there are certain security issues to consider not every command can be implemented by each user on specific clients. Without additional entries only commands entered in the system directory at <SESAM_ROOT>/bin/sesam are allowed. Within these commands, e.g. a Shell Script, any desired commands can be released to selected users. If a command should be started from another directory before the regular backup tasks, this must be entered/permitted at the target client.

UNIX External commands are only executed when the user name and the command are entered into the file /etc/sesam_cmdusers.allow at the client computer.

Format: 'user command|* ( * = all commands )

          is started with su - user

Windows External commands are only executed when the user and the command are entered in the registry of the client computer, in key text: HKEY_LOCAL_MACHINE/SOFTWARE/SEP Elektronik GmbH/sesam/ HKEY_LOCAL_MACHINE/SOFTWARE/SEP Elektronik GmbH/sesam/CommandEvents/user/command

command           execution
*                 all commands
specific command  this command only
cmd /c            all DOS commands ( dir, etc. )
DOS-Command       this command only


Additionally on the client computer the entry

CTRLD_Path=ID/bin/sesam;ID/bin/sms in the file

ID/var/ini/sm.ini in section [CTRLD_Server] must be extended with the directories where the desired programs reside.

command Run
* all Commands
Specific Commands only these
cmd /c all DOS Commands ( dir, etc. )
DOS-Commands only these


Note

Many errors are made when setting up the desired user permissions and allowed commands:

  • The necessary entries are not entered in the target client directories, not entered in the server or entered incorrectly.
  • Instead of entering the command as a key it is entered as a character string.
