Weird happenings on data loss and backup

Re Q10
At work my blackberry files somehow were synced to my computer even though I never intended them to be. I deleted my blackberry files off my computer. A few hours later I was missing a lot of pictures and music files. Some pictures and music were each on the device and my CD card.
No problem - on my home computer I just made a full backup. I did a restore and I am missing the same pictures and music files. Does the backup program backup the SD card also? How did my files get deleted off my blackberry in the first place. I guess some wireless sync? Its possible the files I lost were on the SD card which was never backed up? Is there any way to get the mssing data back?

Hi KayZerSoze,
"There are disk operations in Hyper-V (powershell or GUI) to create a new "fresh" VHD, to replace the "suspect" VHD?"
I'm afraid there is no such a way .
You may try to use hyper-v manager to create a new VHD file then attach it to that VM :
If the issue persists , I would suggest to contact ArcServe for further assistance .

Complete data loss and can't hot sync to user - Zire 72

I had a complete data loss on my Zire 72s due to battery drain. I have the palm desktop back ups on a pc Windows vista and mac os 10. I reset the device and now cannot get it to identify the desktop user account to sync and can't seem to find a way to add the same user name to the handheld.
Any information, steps to help me out would be great so I can get the info back onto my zire.
p.s. I also lost my solitaire game and where I can download this app again would be welcome as well.
Thanks.

URGENT - Data loss and query re-execution

Is there a way to re-execute a VO and not lose data still not persisted to DB?
Or can I select and store rows not yet committed and, later, put it back on a VO instance, in a simple way?
This is needed to develop a wizard-type application, that persists data only at the end. The user must do a random number of searches and inserts on several tables, so I cannot see a way to insert row, requery data when needed and still mantain control. This is so easy with Hibernate, can't it be done with OAF?
Commit data before last step of operation is out of question.
Thanks for attention,
Elner Ribeiro.

Thanks so much for the response.
My VO is an EO basedVO, indeed. I don't need to mantain a specific current point in VO, but when I re-query it (VO) I'm losing all data not saved.
Is there anything wrong with my approach?
Thanks for your attention.

No sleep mode at low battery - data loss and time reset

I'm having this issue for about a year now:
When I run my macbook pros Battery down, there comes the low battery warning. After a while the system just goes down without suspending anything to my harddisk. When I restart my computer it does a normal start and after logging in I'm experiencing a lot messages due to the reset time. I correct my system-time and restart my mac and the system is back to normal.
Usually I'd say: Replace your CMOS-Battery (I know I have an EFI-Firmware), but where is it?. Or in other words: Is there a "System"-Battery, that would prevent my mac from forgetting the time?
Since I'm not running down my battery to 0 very often I only experience this issue from time to time and never took time to do anything about it.
I would also appreciate a workaround so that my mac immediately starts shutting down, after the low battery warning. That would be great.
iStats battery-Status says: Health:83%, Cycles:333, charge 50%...

Well, the problem, seem's to have reoccured: Battery ran out (even the indicator leds on the side didn't show any life), Time reset to 1.1.2001, again some rebooting and setting the time again...
Is this a sign of a degrading battery health status?
It looks like reseting the SMC didn't help after all.

Bearing Data Loss

Hello Experts,
I have taken backup full on 21 JULY 2011 9:00 am and I have taken archivelog all backup 21 JULY 5:00 pm and then in the next morning I took another full backup on 22 JULY 2011 9:00 am,now i have confusion about the archivelog all backup is it still required after full backup taken on 22 JUL 2011 9:00 am
we can bear data loss and I want to restore the database till last full backup of 22 JULY 2011 09:00 am or assume I have lost my archive backup and archive files too,can we restore database without archivelog backup and files ?
Thanks in advanced
Regards,
Asif
Edited by: Asif Hussain on Jul 21, 2011 11:29 PM

If My database has created more than 1000 archivelog files since 6 month before to till date,so I have required all archive files till today with Full backup ?
Ans: No, you need all the archive logs after your last full backup taken.
DB Created: 1st Jan, 2011
Last Full RMAN backup: 20th July, 10:00 AM
Then to recover the database without any data loss you need full backup of 20th July 10:00AM + all archive logs after the full backup.
## Time based recovery
startup mount;
restore database until time "TO_DATE('29/10/10 19:00:00','MM/DD/YY HH24:MI:SS')";
recover database until time "TO_DATE('29/10/10 19:00:00','MM/DD/YY HH24:MI:SS')";
alter database open resetlogs;
## SCN based recovery
startup mount;
restore database until scn 10000;
recover database until scn 10000;
alter database open resetlogs;
## log sequence based recovery
startup mount;
restore database until sequence 100 thread 1;
recover database until sequence 100 thread 1;

Question: Will non committed persistence data loss if my application which is using Kodo/JDO crashes???

Hi,
I am very new to JDO and Kodo and I am still learning. I have a user
specification that requires no data loss when the application crashes. If I
am developing my application using Kodo for data access layer, when my
application crashes just because and needs to restart, what happen to all
the persistence data that have not committed to database??
Vivian

I am very new to JDO and Kodo and I am still learning. I have a user
specification that requires no data loss when the application crashes.
If I am developing my application using Kodo for data access layer, when
my application crashes just because and needs to restart, what happen to
all the persistence data that have not committed to database??If an app crashes, all current transactions will be aborted. There is a
difference between data loss and aborting the current transaction. Data
loss implies losing some persistent data -- data that resides in the
database. That won't happen with Kodo.
You will, however, lose any changes that have not been committed to the
database yet. This is a good thing. You absolutely DO NOT want an
unfinished transaction to be recorded, because that could violate the
integrity of your data. Consider a transaction that decrements from one
bank account and increments another to implement a funds transfer. You
certainly wouldn't want to record the decrement unless you are absolutely
sure the increment would be recorded too!

LR catalog and backup vanishes

A nice little surprise just now when I opened LR. I got a dialog box titled Confirm with a header saying 'Lightroom catalog was not found.' Then 3 lines saying catalog at blah blah could not be found and would I like to locate and existing catalog or create a new one. I searched my system for any occurence of each of the 3 listed files, .lrcat, .lrdb and .aglib using various wild card combos but could find no such files.
I had done about half a dozen full imports as I've never trusted LR but use it mainly for ongoing testing purposes in my business. I had done backups per LR's routine but no offline backups as the imports/metadata wasn't critical. I've had no system or LR crashes and just used LR a few hours earlier.
A rather odd issue to say the least and I'm glad I wasn't using it for prime time use. I woulda been backing up externally as I do all other data but we all know the gaps that can occur between data change and backups.
Just a FYI for the developers,
VG

Yep, right where they always were before:
C:\Documents and Settings\COMP\My Documents\My Pictures\Lightroom
I could possibly do an unerase search and find the old cats, but I don't care at this point as nothing valuable was lost.

Unexplained data loss

Unexplained data loss even when computer is turned off. No hackers. No extra wifi units. Just account drains usage in one hour.Running daily Virus Scan. No other person in house can access.Woke up at 3 am had 830 mb a hour later had zero mb

Kirradog01 I too have experienced a high unexplained data loss, and have had no joy in finding a solution. Can you tell me how you managed to solve your problem??? You might like to catch up with my past query on this forum, I've torn my hair out trying to figure out why this is happening, & short of having to call an "overseas" call centre, I'm at a loss. I guess I could try the Ombudsman, but then that would mean presenting facts & figures..........which I have, but I'm sure it will be a hassle................ Maybe you can provide an answer for me?? Thanks, MegsMum

I need a reliable (auto reconnect, no data loss, etc) TCP/CP Socket class

I have been searching for a third party (free or pay) socket class that will do things that all of us programmers must do:
reconnect when socket is disconnected
reconnect and re-send data (so no data loss)
and implementing all of these other features that we all require for "reliable" network communications over public networks.
I would like to use this socket class on both my client and server applications. Does one exist somewhere? It certainly must. I want something that is tried and proven. free is great with open source but paying money is okay too. thanks !

I am surprised at these responses. Using JMS or creating my own ARQ seems to not meet my requirement (lots of overhead in the case of JMS you usually need a middle "server" and the overhead is huge in high bandwidth situations -- lots of cpu and extra bandwidth -- and the ARQ is a nice idea but i really dont want to create anything myself)
The fact is TCP/IP is unreliable over the internet. anyone who tries to use sockets over the internet recognizes this. It is not an issue of my application but the fact of the internet. the internet is designed with the assumption that the internet is unreliable (hence why the government created ARPA and the internet)
so what if i loosened the requirement and said it was okay to lose some packets, but i just need something that knows the other side is alive and will reconnect/discnonect appropriately? doesnt this exist already? i mean every tcp/ip programmer is doing this and anyone who implements tcp/ip with the assumption that the "network is reliable" is going to be in big trouble. It doesnt need to be TCP, it can be a reliable UDP (i dont care what transport is used) but i just need something where i can take my existing code, drop in this new class instead of "Socket" and get my project done. it would be nice if it had features like reconnecting, dropping data if it is too old or if there are too many messages. i will be using it in high bandwidth applications (20-50mbps over the internet) and dont need 100% packet reliability, if we drop some packets due to a hiccup that is ok, but i do need it to be intelligent in reconnecting and such.

[DATA LOSS] I closed the Tab Groups and all my tabs dissapeared. How can I recover the tabs in Firefox 26? Would you please just delete this feature?

Thank-you in advance for reading all of this.
A slip of the mouse in trying to return to the left-most tab caused the tab groups feature to take over the window. I completely failed to comprehend what I was looking at and closed the thing by clicking the x because I damn sure didn't want what I was looking at. Undo close group? Of course not, I didn't want a group in the first place. Hey! My tabs are completely gone now! So in just a few steps all of which seemed innocent, I have lost all but ten of the tabs that were open, and those were only the most recent ten (and actually older tabs would have been more valueable than newer so insult on top of injury).
I don't think increasing the number of undoable tab closures is the answer. I think getting rid of the tab groups feature all together is the best way to go. I seem to have lost all the tabs I had open, irretrievably, and some of them had been open for WEEKS so they can't be reopened from history.
The tab groups feature is a data loss bug. Please remove it from the UX completely. If you have to figure out a way to grandfather people who actually have a tab group, fine but don't further vex me with it, please.
The reason this catastrophe has occurred is that your feature, was so discoverable that I activated it by mistake, and the UI after that had to be learned on the spot, yet was too complicated to learn. You really should withdraw it until you can figure out how to keep the UI for it from causing data loss such as I have experienced this morning.
Also, there may be other questions on this feature which are from a certain point of view the same as this one. It's hard for me to tell for sure. None of them had a true resolution so that's why I posted this one, also I'm seeking a specific fix, removal of the offending feature.
Why remove the feature? Because if I allow in my discussion the possibility of retaining it, it will stick around in its present and dangerous form until your team is done bikeshedding the new form it should take. Instead I want you to delete the feature and then require its champion to convince you that a new incarnation won't cause data loss before you allow it back in.
Fellow users, if you know of a way to recover all 50 lost tabs from an "undo close tab group incident", I would be grateful for that advice, but I would still believe the feature should be deleted. Some of the tabs have been retained for months so digging them out of the history is not practical.

I am not 100% certain but I am fairly sure development of this tab feature has ceased and it is likely to be deprecated. I am even less sure what the replacement will be.

I have not tried this and am not even using Windows at present but the tabs groups are stored as entries in the sessionstore.js files. Firefox has such a file plus sometimes numbered copies and a backup copy. Firefox will have re-writen these files but I suppose there is a posibility the Windows OS may have kept copies.
* see http://windows.microsoft.com/en-US/windows7/Previous-versions-of-files-frequently-asked-questions
* http://kb.mozillazine.org/Sessionstore.js Note the files are kept within the Firefox Profile
** Firefox Button -> Help -> Troubleshooting [open profile] (or some thing similar) is one method of locating the profile.
Find and backup any current sessionstore.js file. Consider also bookmark or otherwise recording anything you have open. Now find any previous versions and try putting them in Firefox's profile before restarting it.

What can I do simply to keep all my previous contents, (own pics, videos, etc.) on my previously authorized iPad on PC, but get a new authorisation and a right syncronization, without data loss with a new iTunes on my new Mac?

Friends,
I already had an iPad(1) and its full contents (not only the purchased items, applications from Apple, but my all own pics, videos, songs etc.) is normally syncronized with an authorized PC (Windows) computer.
Now, I've bought a new MacBook Air computer, and want to sell my PC. But I don't know how to transfer (or syncronize) all of the contents from my previous iTunes on PC to the new one on the Mac.
When I connected my iPad to my new MacBook Air, I promted, if I want to change authorization of my iPad to the MacBook.
But also got a warning, that the new iTunes will delete from my iPad all my previously syncronized items, pics, videos and music, with the previously authorized iTunes on the previous computer, expect the saved pics from the net.
What can I do just like that, simply to keep all my previous contents on my iPad, but have a new authorisation and a right syncronization, without data loss with the new iTunes on my new Mac?
Thanks a lot for your answer.
([email protected])

Here are some instructions that I have posted several times that may be helpful to you as they have been to others. You can simply ignore anything that does not apply or that you have already done.
As Alan stated above - transferring the iTunes library is the best first step. If you can transfer the iTunes library to the Mac, most of this will be unecessary for you to do.
Very Important ....
1. Authorize the computer.
2. Turn off auto sync in iTunes
3. Transfer purchases
The text in italics is from the other thread - non italics are my words.
The following was copied from this thread. This is essentially what you want to accomplish.
https://discussions.apple.com/message/11527071#11527071
1) Without connecting your iPad to your new computer, start iTunes. Click on iTunes. Click on Preferences. Click on Devices. Check the box next to "Prevent your iPod etc. from automatically syncing." Click OK.
2) Now connect your iPad to your computer and start iTunes.
3) When iTunes starts, right click on your iPad under Devices in the left column. Select Transfer purchases etc.
4) After it finishes transferring all your apps to your computer, right click on your iPad and select Backup your iPad.
5) After it finishes backing up your iPad, right click on your iPad and select Restore etc.
6) After it finishes restoring, left click on your iPad , then click on the Apps tab on top, and check the box next to Sync Apps, then click on Apply below.
If everything on your iPad looks good after the sync, go back and click on iTunes / Preferences / Devices and UN-check the box next to Prevent your iPod etc. The only other thing you may want to check is if your contacts, bookmarks, etc. are syncing correctly now. If not, go to the Info tab after connecting and make sure you indicate which features you want to sync with what sources.
Read this thread and the support links as well. There are apps that you can purchase that will allow you to transfer photos from the iPad to your computer. Look at Photo Transfer App in the App store and you can search for others as well.
https://discussions.apple.com/message/13016026#13016026
This support site will help you with transferring iTunes music to your new computer.

One final note - you may want to leave auto sync turned off - but that is totally up to you. I never did use auto sync.

EZ Media and Backup - all data disappeared

I have an Iomega EZ Media and Backup 2TB system I've been using for about a year with no problems.
Yesterday had a very strange issue, was having trouble connecting so rebooted with button on the back (pressed for under 5 seconds).
Drive shut down, hit the button again to turn back on, connected from laptop, all my files, about 1.8TB are gone!
User accounts, settings, directories are all still there, but all files are gone and picture at the top shows the drive as being empty.
Is there any way for me to recover this?
I believe everything was fine after upgrading to firmware 4.0.8.23976, but I'm not 100% that didn't cause the issue.

Hi mattgaines,
Pressing and holding the power button is not recommended because it may result in data loss. I'm not sure if this is the cause since you said it was for under 5 seconds, but it is possible. It could also be the firmware on the device. Some customers have been able to get their data back by adding the shares back by the same name, but since the directories are still there that might not work.
Is this device still covered by the warranty? I think it would be best if you contacted technical support to see if they can troubleshoot the device to get the data back. However, data recovery is not covered under the warranty. If the data cannot be retrieved, you will have to use a data recovery service to try to get the data back.

How can I force Time Machine to make a complete backup of my Hard Drive. I just installed a new external drive for Backup since my previous one failed. Now when I back up, Time Machine only backs up my data folder and the Users folder.

How can I force Time Machine to make a complete backup of my Hard Drive. I just installed a new external drive for Backup since my previous one failed. Now when I back up, Time Machine only backs up my data folder and the Users folder.
When I start a backup. Time Machine says "Oldest Backup: None; Latest Backup: None", so it seems like it should do a complete backup, but it only does a partial.

System altered. Upto this i was clear, but now i cann't understand when you actually dropped the control file from you database(in running stat) how can you perform "alter system checkpoint" and other "alter tablespace.." command? Once controlfile is inaccessible, oracle database is not suppose to function.
