How to sync two time capsules?

I have two time capsules on my network and want to set them to automatically sync files between them for redundancy. How do I do this?

In theory, you could have another application like Carbon Copy Cloner or SuperDuper backup Time Capsule 1 to Time Capsule 2, but the same risks apply.. I haven't tried this....and won't....but maybe another user has.
Agree with Bob.. what you can do and what you should do are different. It is possible to use CCC and put the two TC in sync. The result will still be only as good as the quality of the first disk. That is a very slow way to backup.. TC is not designed as a NAS so it has no internal ability to sync files. It is purely designed as a target for Time Machine.
If you do use CCC all packets are copied via the computer.. over the network.. so if you use wireless expect to never finish.. before the next TM backup starts and CCC will still be syncing.. ie you will have created an endless loop. Don't do it.

How to have two times the same iTunes library ?

My parents are separated, so I have two computers (one with my father and the other one with my mother) and all my music is in the computer with my mother, I want to have the same iTunes library to my father how I should do?

Not an easy one. Maybe you can try on both computers ) if they are both Macs or both PC to setup your iTunes Librery to be on an external USB drive. Under Windows make sure the USB HDD always mount with the same letter. Both computers should be Authorized for your account.

How to synchronize two timer/counter tasks?

Hi,
I'm programming DAQmx through the nicaiu.dll with Matlab. I'm trying to start two different tasks, each controlling ctr0 and ctr1, respectively. Both timer/counter tasks should start on a common trigger, in my case /Dev/PFI0. Having searched the forum, I do understand that both tasks can't be triggered off PFI0. Instead, I probably need to trigger one of my tasks on a signal that turns on whenever the first task starts. My question is; What signal can inform my ctr1 task that my ctr0 has started? I basically want these two tasks synchronized, but not pulse by pulse since the pulse trains are quite different.
Trying to trigger both off PFI0 results in a resource conflict. Triggering ctr1 on ctr0gate doesnt work either.
Also, I need ctr1 to trigger on when the ctr0 tasks starts, i.e. not when the first ctr0 pulse appaers!
Thanks,
Per

Thanks Ryan.
I made some changes to my code now and it appears I CAN trigger both counters off PFIO (on an E-Series board). I only recently converted all my Traditional code into DAQmx, and got lost in my tracks. I was trying to generate finite pulse trains on both counters, and had used Finite timing on the counters to generate finite retriggerable pulse trains, without knowing that tied up the second counter. I solved this now using Pause Triggers instead. In the case where I generate single retriggerable pulses I still use a Start Trigger, and I can now Start BOTH counters using DAQmxCfgDigEdgeStartTrig and listening to PFIO with both counters (each counter running off a separate task).
Sorry, I got things confused, and your solution isnt required anymore. Similarly to your solution, though, I have always used a (real) analog output routed externally to the PFI0 pin on my E-Series board as the synchronizing trigger. However, if I could avoid the external wiring it would be nice, so I will explore your solution a bit more
I am not familiar with the concept of a 'dummy' task/channel. Can you point me to more documentation on this?
I already use the analog inputs on this board from another app. Will creating a dummy AI tie up all analog inputs, so I can't then access my physical analog inputs from other applications (on the same board)?

Hi,
Use TO_NUMBER to convert those strings into numbers that you can add.
Use TO_CHAR to convert that number back into a string.
In PL/SQL:
minutes := ( ( TO_NUMBER (SUBSTR (:psttime, 1, 2))
          + TO_NUMBER (SUBSTR (:pettime, 1, 2))
        * 60
        ) + TO_NUMBER (SUBSTR (:psttime, 4, 2)
          + TO_NUMBER (SUBSTR (:pettime, 4, 2);
str := TO_CHAR (TRUNC (minutes / 60))
    || ':'
    || TO_CHAR ( MOD (minutes, 60)
                   , 'fm00'
            );In SQL, compute the NUMBER minutes in a sub-query, so you can use the alias in a super-query.
This assumes that :psttime and :pettime are always well-formed: 2 digits for the hours, a colon, then 2 digits for the minutes. If you're not sure about the number of digits, the same basic approac will work, but the SUBSTRs will be a little more complicated.
I hope this answers your question.
If not, post a complete test script that people can run to re-create the problem and test their ideas. Include VARIABLE, CREATE TABLE, INSERT or whatever statements are necessary to provide some sample data, and also post the output you want from that sample data.

            System.out.print("job Fired "+new Date()+" by "+t.getName()+" ID :"+t.getId());
            sleep(5,System.out);

I'd only use one timer and write a dispatcher task that stores the time at which job2 is executed. If the last time is more than one minute past, execute job1, reset the time tracking field, and execute job2.

I think that PROMPT SELECTINPUT should be able to do what you need: have 2 selections of same Dimension in one Package. Take a look at example given in the documentation [http://help.sap.com/saphelp_bpc75_nw/helpdata/en/e9/23ece2cfd7489f8aa457d78d306a38/frameset.htm].

Subtracting two time Stamps

Hello all,
thanks for looking
I am subtracting (systimestamp - "TIME_IN") as "HOURS_WORKED"
(08/30/2010 04:42PM - 08/30/2010 04:00AM) ="HOURS_WORKED"
the column is called hours worked, the 'hours worked'columns shows '+000000000 12:42:58.9881'
I understand that hours worked are 12 hours 42 mins and 58 seconds.
is there a way i can format this column to just show me hours and mins?
from '+000000000 12:42:58.9881' to 12:42?
is there an easier way?
Thanks in advance

The difference between two points in time is not another point; it is an interval. Make c an INTERVAL DAY TO SECOND, like this:
declare
     a timestamp;
     b timestamp;
     c INTERVAL DAY TO SECOND;
begin
     a := localtimestamp;

Subtract two characters in a query

Hi Experts,
I want to know how to subtract two characters in a query could you please give me the solution regarding this.

Help I need to subtract times to find the difference between two times?

Hello there, I really need help.
I'm trying to make this attendance tracking system so that when a user enters his or her ID the system wll remember his/her check in time. However I also need to find out either how late the person is or how early to store their over time and late.
So I get the time by using a timestamp, so I'm left with a timestamp that I store into the db. But the problem comes when trying to compute for the late or over time. To do that I have to get the normal login/checkin time from the employee schedules table in the db and either subtract that time from the checkInTime to compute for how late or subtract the checkIn time from it to find early.
The thing is, the schedule is stored in datetime format in the db since the db is sql. Also I have no idea on how to subtract the two dates via java. The month, date and year stored in the sql db are just fillers, all I need computed is the time difference of the hours and minutes between the checkInTime and the schedule.
I've tried to use datediff: SELECT e.employeeNumber, datediff('hh', startTime, checkInTime) as lateTime from employeeschedules e, timandattendance, contractualemployees c where c.scheduleNumber=e.scheduleNumber and t.employeeNumber=c.employeeNumber and t.checkInNumber=1;
But it keeps on giving out various errors: You have an error in your sql syntax check your manual that corresponds to your sql server version. for the right syntax to use near , checkInTime) as lateTime from employeeschedules e, timandattendance, contractualemployees c where c.scheduleNumber=e.scheduleNumber and t.employeeNumber=c.employeeNumber and t.checkInNumber=1;
My sql server is My SQL 5.0.5

FEBA - How to post two or more transactions at the same time?

Hi,
    one of our banks sends the statemets with many lines that belongs to the same transaction. We have to post partially one line, and afterwards the other line. Any of you know how to post two lines at the same time from the bank statement?
Thank you in advance,
Miguel

Hi,
I'm sorry for replying so late.
The solution I reached was to change the a few things in the standard.
Now I have a new "context menu item". I select two or more transactions and I right-click the mouse. I select that "context menu item" and the next part of the code adds the total amount of the transactions to look for the correct post for the first transaction. Once posted automatically, the next transaction is posted automatically by the system.
I hope you understand my English. I've problem with technical FI terms.

I have two time capsules (1TB, 2TB) and want to use one for another set of Macs (my Family). How do I set both up and keep all the Macs from joining both Time Capsules?

I Have two Time Capsules (1TB and 2TB) and want to set one for business and the other for family - networking seperate Macs to each.

Both should be plugged into the network with ethernet.. if at all possible.
If you have a router already then both bridged otherwise one set to router and one to bridge.
How do you access the TC? Ethernet or wireless?
Are they located in the same area?
You could set different wireless networks.. if they use wireless.. this is nice easy way to do it.
You can set user account in the TC you want the business one to join with.. that will prevent access by the family.
So there is a number of ways.. none are particularly secure btw.. the TC is a home not a business device.. if anybody wants access they press the reset for one second.. pofff all the passwords are default for 5min.. to allow people who forget their password to get access.
On ML you can encrypt TM backups.. this is better for security if that is the problem.. and still use different user profile to prevent access.

How to subtract two time?
