Schedule Snapshots Rotation

Hello,
I have two Hyper-V servers running Replica feature, it is working great, but it only protects me from hardware failure.
Now I want to have snapshots enabled for quick rollbacks (and full backups for more restoring options, but that's for later).
I found this script which describes how to schedule a snapshot each 7 days: https://support.managed.com/kb/a1872/how-to-automatically-rotate-hyperv-snapshots.aspx
From what I understand, it will rotate the Snapshot each 7 days, creating a new one and deleting the previous... but I am looking for something more complicated.
What I really wanted was having a snapshot each 7 days, just like that example, but keeping the last two weeks, and also have a new snapshot daily. So I would always have three separate snapshots instances (2 weeks old, 1 week old and "yesterday").
If I notice performance degradation, I will only keep 2 snapshots (1 week and 1 day old).
Does anyone know how to do it?
Thanks,
Rafael

Hi Brian,
Thank you very much for your answer.
Well, I am not thinking of snapshots as a backup. I am thinking about a fast way to do a rollback in case of need.
Recently I had a problem with a server where the last backup I had was 5 days before, and recover was not very fast (very fast I mean a few minutes, if that much). Snapshots are a way to cover me from that kind of problem.
Because of the quantity of servers I run, most of them have automatic updates. I had a case not long ago that one update messed up the "fonts" on a windows server 2003. I also have some servers where more then one people have access... once a employee
deleted by accident something he was not supposed to.
Beyond having snapshots, I will also have proper backup. Maybe having 2 weeks of snapshots is a little too much. But I think having at least one day and a week always recoverable can save me some headaches.
So... my question is how to make a script to always have a one week old and a one day old snapshot. The script I have for a week is:
$Days = 7 #change this value to determine the number of days to rotate.
$VMs = Get-VM
foreach($VM in $VMs){
    $Snapshots = Get-VMSnapshot $VM
    foreach($Snapshot in $Snapshots){
        if ($snapshot.CreationTime.AddDays($Days) -lt (get-date)){
            Remove-VMSnapshot $Snapshot
    Checkpoint-VM $VM
How to add a daily snapshot without overwriting the weekly snapshots?

  • Cannot schedule log rotation from LMS32 GUI

    All,
    I've been experimenting with the log rotation feature from LMS 3.2 UI (CS > Server > Admin > LogRotation) and have noticed when I try to schedule the logrotation with any backup directory (/var/adm/CSCOpx/log for example) it indicates that I cannot schedule it for that directory structure.  I even tried /tmp which is wide open for writing from any account but it still errors out.
    I am familiar with the logrot.pl -c from the CLI but I need to try this first from the UI.   Has anyone run into this before or know if this is a product issue or a mis-configuration on my part?
    Regards,
    Michael

    Exactly what error are you getting when you try and schedule the rotation?  You should be able to use both /var/adm/CSCOpx/log and /tmp.

  • ISCSI Target Scheduled Snapshots

    I know there are cmdlets to snapshot a target but is there a built in way to schedule snapshots?
    Alternatively, is there a cmdlet to list snapshots for a target so I can create a script to run on a schedule to remove old snapshots and create new ones.

    Yes, you can use Schedule Snapshot Wizard to have automatic snapshots. See:

    Alternatively you can use cmdlets to deal with these tasks (PowerShell would give you more control over
    creation / deletion of a snapshots. See:

    The ones should be of your interest are Checkpoint-IscsiVirtualDisk and Remove-IscsiVirtualDiskSnapshot cmdlets.
    Also you may use SMI-S and WMI if you want to use say C# or C++ and not PowerShell.

  • How do you troubleshoot a scheduled snapshot

    Hello, I have a ton of reports that have a snapshot taken on the 2nd day of the month. Has worked fine until this past weekend when the snapshots did not happen. There is nothing I see in SSRS that explains it. The schedule is still there. Is there a way
    to find the root cause of why the snapshots didn't fire? The server and database were functioning at the time.

    Hi cmunkres,
    As JJordheim posted earlier, please check if the schedule is work well in the report server. In SSRS, we can open the Schedule table in the ReportServer database to check the schedule. And the SnapshotData table is record the data about the snapshot.
    Reference: Report Server Database
    Alternatively, we can check the log file to fine the root case. In SSRS 2012, the log file default location is:
    C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\LogFiles
    Could you please post the error log? It is benefit for us to do further analysis.
    Hope this helps.

    I need to schedule the refreshes every day except Saturday and Sunday. Got any idea how can I do that?
    Prash

    You would probably want to use the dbms_job package to schedule the refresh in that case, rather than scheduling the refresh in the materialized view creation. Write a function that returns the next refresh time for your snapshot and pass that in when you create your job.

  • Analytical snapshots and scheduled jobs

    Hello,
    for extended analytical reports we need to make the snapshots of our statistic datas every day.
    There is an option of doing snapshots of the Project in Project Management, but we need to have snapshots of our own BO's or data sources. Is there any possibility to do this?
    In case snapshots can't be done by the system we also would perform it in coding, by creating business objects with required datas and saving them. But we need to do the saving automatically (regularly).
    In Project Management it is also possible to run scheduled snapshots. How can we schedule jobs (it would be enough if we could execute an action which saves our datas at scheduled time)?
    We have found only "Mass Data Run Process" in this context but the MDR's can be done only for the special standard Floorplans, aren't they?
    Best regards,
    Leonid Granatstein.

    Hi,
    currently it is not possible to create snapshots for partner BO content by a standard process.
    Also defining a mass data run object, which you could schedule and where you could implement the snapshot by yourself, is not available for partners yet.  So we have no standard mechanism available to get your task done with the use of the current implementation possibilities.
    The only option I see is that you develop the snapshot activity on your own in ByD studio.
    To trigger the snapshot activity on a regular basis, I only see the option to trigger this from outside. An option would be to define a web service or an XML file upload.
    You could write for example a small program ( by using PHP or .NET) on a PC which runs on a regular basis and which uploads an XML file or calls a web service. This then triggers the snapshot activity you have programmed in ByD Studio.
    I hope this helps.

  • Pdf  WEB PAGES  -  MISSING SNAPSHOT TOOL (and others)

    I recently installed Adobe reader 9 and this has been a severely retrograde move. My university course makes ALL our lecture notes and documents avaialble OVER OUR INTRANET (i.e. as WEB PAGES) as pdf documents - we used to be able to simply click on the link and view them in a webpage, then use the Adobe snapshot tool whenever necessary to extract pictures or text from the notes (which often have ENORMOUS variations in font size and picture resolution WITHIN the ONE DOCUMENT) and paste them into a temporary document in order to blow them up and print them out so we can SEE them. They also often needed to be ROTATED before they could be printed out.
    Now however, the Adobe reader 9, when we view these documents IN A WEB PAGE, has NO tools that allow us to do these VERY IMPORTANT MEASURES to make our lecture notes READABLE. All it allows us to do is to print it as it is!
    In an incredibly demanding and intensive course, we now have to WASTE TIME we can ILL AFFORD by saving the document (which we DON'T WANT or NEED TO SAVE) and THEN OPEN it, use the tools which suddenly appear in Adobe reader 9 when opening a saved document, do what we need to do to print out something readable, then remember to delete what we've saved.
    This we have to do OVER and OVER AGAIN - it is UNELIEVABLY INCONSIDERATE and ANNOYING.
    We are already under HUGE pressure in our course, and students in the REAL WORLD do NOT have rich American mummies and daddies who pay all our expenses - we CANT AFFORD to buy every new expensive Adobe program just because our university decides to use pdf for everything.
    If anyone has information that there IS a way to do snapshots, rotation etc on a pdf document VIEWED IN A WEB PAGE, could you please advise us here? Thankyou!

    Thnakyou for your reply - there's definitley no way the uni will change their standard format, and it's really not their fault anyway. I wanted to re-load Adobe 7 but can't find it anywhere on the Adobe website, and do not want to risk loading it from elsewhere!

  • Manage btrfs snapshots

    One of the feature that i much like about btrfs is Snapshot.
    What i want to do is to create snapshots of /home every 5/15 minutes (i have to test better the impact on performance) and retain:
    02 - Yearly snapshots
    12 - Monthly snapshots
    16 - Weekly snapshots
    28 - Daily snapshots
    48 - Hourly snapshots
    60 - Minutely snapshots
    The above scheme is indicative and i'm looking for suggestion in order to improve  it.
    After long google searching finally i've found a very simple but powerful bash script to manage btrfs snapshots: https://github.com/mmehnert/btrfs-snapshot-rotation
    I've changed a bit the script in order to use my naming scheme
    #!/bin/bash
    # Parse arguments:
    SOURCE=$1
    TARGET=$2
    SNAP=$3
    COUNT=$4
    QUIET=$5
    # Function to display usage:
    usage() {
    scriptname=`/usr/bin/basename $0`
    cat <<EOF
    $scriptname: Take and rotate snapshots on a btrfs file system
    Usage:
    $scriptname source target snap_name count [-q]
    source: path to make snaphost of
    target: snapshot directory
    snap_name: Base name for snapshots, to be appended to
    date "+%F--%H-%M-%S"
    count: Number of snapshots in the timestamp-@snap_name format to
    keep at one time for a given snap_name.
    [-q]: Be quiet.
    Example for crontab:
    15,30,45 * * * * root /usr/local/bin/btrfs-snapshot /home /home/__snapshots quarterly 4 -q
    0 * * * * root /usr/local/bin/btrfs-snapshot /home /home/__snapshots hourly 8 -q
    Example for anacrontab:
    1 10 daily_snap /usr/local/bin/btrfs-snapshot /home /home/__snapshots daily 8

  • Sjsws7 log rotation policy using CLI

    Is it possible to set the log rotation policy using CLI.
    We want to script the process of log rotation using CLI instead of configuring it from the console.

    Thanks for you interest in Web Server 7.
    Yes, Web Server 7 has a rich CLI and
    Log rotation like most administration tasks is configurable using the CLI.
    To schedule log rotation you need a create an "event" . The event as can be seen from the usage could be restart/reconfig/rotate-log/rotate-access-log etc.
    wadm> create-event
    Usage: create-event [--echo] [--no-prompt] [--verbose] [--no-enabled] config=name command=restart|reconfig|rotate-log|rotate-access-log|update-crl|commandline ( (--time=hh:mm [--month=1-12] [--day-of-week=sun/mon/tue/wed/thu/fri/sat] [--day-of-month=1-31]) | --interval=60-86400(seconds) )
    CLI014 config is a required option.
    I will walk thru the steps in the CLI starting from scratch..
    1. Create a config.
    2. Create an event
    3. Create an instance of the config
    4. Start the instance
    5. Deploy the config ( This is a workaround. You should not have to to do this in the upcoming Technology Preview Release 3).
    That's it.. The log should be rotated as per the parameters specified when you create the event.
    I am pasting below the actual result of following the above steps.
    In the example below the event scheduled is a rotate-log event. rotate-log rotates the error log. If you need to rotate the access logs use rotate-access-log instead.

    after all 5 inputs are given .
    why i was not getting output after one input.why
    hy the thread out was waiting for remaining threads
    input.Probably because of how the scheduler was rotating among the threads while waiting for input and queueing up output.
    When you call readLine, that thread blocks until a line is available. So it probably goes to the next thread's readLine, and so on. All threads are probably blocked waiting for input before you enter a single character.
    Something inside the VM has to coordinate the interaction with the console, and between that and your threads, the out stuff just doesn't get a chance to display right away.
    In general, you can't predict the order of execution of separate threads.

  • JDBInsight 2.0 Announced - See @ JavaOne Next Week

    DUBLIN, IRELAND - 5 June, 2003 - JInspired (www.jinspired.com), a leader in J2EE™ transaction analysis, today announced JDBInsight 2.0, the next generation of J2EE performance management products from JInspired. JDBInsight will be available for preview at JavaOne 2003 in San Francisco.
    JDBInsight is the first product to effectively integrate Java profiling information with JDBC/SQL transaction analysis. Version 2.0 has numerous features derived from its support of the Java VM Profiling Interface (JVMPI) such as Java call stack analysis, CPU, blocking and waiting measurements at the transaction path level.
    The "Best Java Application Monitoring Tool" just got better. JDBInsight 2.0 sports a new client interface that once again shows that JInspired is the leader in delivery of rich and informative visualizations of J2EE transactions and performance execution. The products innovative use of symbols and graphics is unrivalled within the Java performance assurance industry.
    With the new Java call stack classification engine developers, testers and J2EE administrators can now understand the interaction of various technologies with corporate databases. Classifications engines are available for Java enterprise technologies such as EJB, JSP, Servlets, JTS, CORBA, JDBC, JCA, Web Services, JDO and Struts. JInspired will also be announcing new engines over the coming weeks for various web/persistence technologies such as JavaServer Faces, Tapestry, WebWork, and Hibernate.
    JDBInsight 2.0 is the first performance management product to have the ability to detect and present resource transaction demarcations – allowing visual sub-transaction identification.

    In addition to the JDBInsight Version 2.0 feature rich client interface, JDBInsight also provides a suite of functional command-line utilities, JDBInsight 2.0 Terminal Services. The Terminal Services component of JDBInsight 2.0 delivers the server to a wide variety of desktops without the need for graphical environments. The JDBInsight 2.0 Terminal Services provides a quick and easy way to communicate with multiple servers without having to use a graphical user interface. This facilitates the streamlined connection, activation and deactivation of profiles on local or remote servers with the ability to control multiple servers from a single terminal.
    These Terminal Services also provide a powerful environment to create and schedule snapshot information, in order to monitor servers at regular intervals, with the ability to store and retrieve snapshots from any mounted drive, as well as providing a rich set of commands to assist in analysis of this highly detailed data.

    About JDBInsight
    JDBInsight is an innovative enterprise development product, aimed at simplifying the performance tuning and testing of J2EE™ applications, which access data through the Java Database Connectivity (JDBC™) API. JDBInsight analyses the access of enterprise data by J2EE™ client-, web-, and bean containers. The analysis can encompass transaction executions, from multiple J2EE™ containers. JDBInsight captures timing and execution information for enterprise data accessed by Servlets, JavaServer Pages, Session- and Entity Beans using JDBC™ or an Entity Bean using a container's persistence engine. JDBInsight can also profile non-J2EE applications that access enterprise data through the JDBC™ API.
    About JInspired
    JInspired located in Ireland, delivers JDBInsight, a comprehensive solution for Application Performance Tuning and Testing that focuses directly on early identification within the development and testing lifecycle. Jinspired offers sophisticated analytical tools, that capture transactional behaviour and performance timing information, across multiple containers in a single console, and presents this information intuitively to the user "Visualizing the Invisible”.

    Glad to hear I'm not the only lucky one! Reading these forums has helped me a lot, but it has also made me a bit paranoid. I understand that Support > Discussions is by its nature focused on problems, though. I've always thought that technology companies tend to focus more on adding features, whereas they'd be better off to focus on making all the features work properly all the time for everyone! Apple has often been a leader in this regard (best overall service record of any major hardware company by numerous consumer polls), but they've been growing fast lately and I confess I fear their quality control may have some challenges 'scaling' to the larger size of their user base. It's great to see so many helpful users in these forums trying to act as volunteer apple support staff!

    CPU speed may play a role but after experimenting with Activity Monitor it looks like available memory is key. For example if I export a 100% crop of a 10 megapixel RAW file to JPG it sometimes takes over a minute. When this happens there is essentially zero free memory. Also, preview updates are usually running in the background. At other times there is ~100MB free memory and it performs better.
    I do agree with a post elsewhere that on my machine, at least, the sliders have so much lag it is hard to get the effect you want. Constantly over and under shooting. Might be livable since some nice effects can be had if you work at it.
