Why backup

This is a suggestion for apple. I have a lot of stuff on my Macbook Pro. And a lot of music. When I delete all my movies I am left with 18.9 GB. I would pay extra to have the music I bought from iTunes which is most of my 4000+ songs archived on apple server. Why should I have to backup my music on my computer or an external hard drive when apple, I assume, as a state of the art backup system themselves. It would also be a good way for client to use iTunes and for the music industry since you could only access music you paid for.
So for me it's a win, win, win & win solution.

*Why should I have to backup my music on my computer or an external hard drive when apple, I assume, as a state of the art backup system themselves.*
They are your files. If Apple were to allow re-downloads they would have to pay the recording companies again to re-downloading them. Its how the licensing works. Do you expect Microsoft to backup your documents? After all you can buy office online. Backing up data is an individual responsibility especially when it is your data.
Apples serves have backups, but that is very different since their data exist in multiplicity on their server farms.
*It would also be a good way for client to use iTunes and for the music industry since you could only access music you paid for.*
Why should Apple be responsible for your stuff? The whole point of iTunes is that you own the content you buy. For that to happen the files must exist on your hard drive in its entirety. If the music were to live on Apples side, you would be "renting" your music. Something that nobody wants.
Point of the story. Storage is real cheap. You can get over a quarter of a terabyte of storage for about $100. Its an important investment for your important information.

Why Backup When *Starting* LR?

LR prompts me to do a backup when I open the program. I have looked for a way to change this to prompt me to backup when I am leaving the program - which seems to make more sense - but I can't find a way.
(1) What if anything am I missing in the settings?
(2) Why backup before you've done the work as opposed to after?
Thanks,
--Bob

1) You can't back up after, presently (would be a nice addition).
2) So you have a backup before you mess up something.

**Tech explanation why BACKUPS take long, how to make it very short, etc*

I noticed my backups to increase quite a bit over the last few days. I also noticed so many posts on why are backups taking so long, what can I do (only solution given is to click x or modify so that backups are not done, etc). Well to answer all those that want the "real" answer, I decided to do a few minutes of research and share what I've learned. I have seen nothing at all on google or anywhere else about the recommendations I'm suggesting, but from my experience I think it will answer 99% of all the backup threads on this site.
All your backups are being stored in:
XP: C:\Documents and Settings\(Your Name)\Application Data\Apple Computer\MobileSync\Backup\
Vista: C:\Users\*Your User*\Appdata\Local\Apple Computer\
Mac: ~/Library/Application Support/MobileSync/Backup
The main directories are GUIDs that are based on the version of the iphone, so you may see more than one folder. Make sure to view the date last modified of the folder to make sure you go into the latest one. Order the files inside this directory by date modified. Here you can see how many files are being updated ON EVERY BACKUP. The older ones are not being backed up anymore because you probably uninstalled that app on the iphone (apple doesn't delete old unnecessary backup files that won't be ever used - bad programming #1). They are encoding all these files and inside the files in base 64, so you can decrypt them to view the contents, but you don't really need to and I don't have to show how for the solution to this. Open a file in wordpad. Within the first few lines you'll get an idea of what the backup is.
So here is the solution....sort these files by date modified. My biggest single file was 29,582KB!! looked inside and it's the WeDict app. There are other files from WeDict, but obviously for me if I want fast backups I need to get rid of this app. A few other top files I found are awesome apps on the iphone that have awesome trailers, intro movies for games, etc. Well guess what, they backup every single game intro, trailer, etc. So for instance, the game tap tap tap has a few m4a songs....well every one of those m4a songs are encrypted and backed up EVERY TIME (apple backups up files that don't need to be backed up which would probably reduce backup times by at least 98% - for instance, intro movies don't need to be backed up, nor app songs, nor game instructions, etc because that information should be on itunes backed up separately when you install an app, not when you do backups and it should be smart enough to update that folder when a new version is out....and only do backups on files that can change like high scores in apps, notes, etc - bad programming #2).
So anyway, you can see which apps are taking the most amount of time. Obviously if you remove every app on your iphone, it will backup fast, but some of these apps are shockingly huge. Problem here is that you can have 1 file or 100 files associated with 1 app. You could have only 2 apps installed on your iphone and your backups could be slower than a person having 30 apps just because some apps take a ridiculous amount of more backup data and time and what makes this even worse is every part of the data is encrypted, which I will talk about below (which doesn't need to be). Only time that file is not going to get updated is if it's deleted from your iphone.
You don't HAVE to use base 64 encryption. Come on now, especially on apps? They could lighten the encryption and it would be much faster backups because it has to decode and encode every file now. You are overencrypting these files so huge programs take forever backups. (Bad apple programming #3 don't over encrypt when speed is a necessity on something that doesn't need extreme high security).
As a developer with a computer engineering degree, to also make it even faster than what users were experiencing with backup times prior 2.0. They are obviously not tagging each portion that needs to be backed up individually. Lots of software companies do this to speed stuff up. For instance if you have Kaspersky antivirus with the defaults, the first scan will always take long, but every scan afterwords will be fast because instead of rescanning that file for a virus, it just checks to see if the checksum has changed and if so rescan that file, so most of the time the scan will happen fast unless there has been a period of time that you haven't done one that updates the checksums. They could do something very similar with this. So basically even if you changed a few things on your phone, the backup should be only a few seconds because only those few changes would be signaled to be rebacked up. (bad apple programming for backups #4). This process can make backups be from 98% faster to 99.98% faster....meaning having a backup only take 4 seconds even with 100 apps installed. Actually coding this one thing would make it extremely fast, but would take the most programming time. You can even make an algorithem where for the whole backup process it would just have to read one file that it would check checksums and then tell it to modify 1 or 2 other files and that's it as opposed to backing up (for me almost 5,000 files) some being several MB in size.
So all the above should give apple suggestions on how the can speedup backups by 99.98% faster than how they are doing it now and then anwers all those questions why it takes longer, what needs to change, how can I shorten my backups (this way you can find out what apps are taking the most time), etc.
The problem here is apps will continue to grow, become larger, more trailers, movies, songs embedded inside apps, etc. This problem is only going to grow. The additional problem is that they can say they have tweaked the backup programming to make it faster, just like they did in 2.0.1, but backups seem slower because there are newer better more awesome apps out!! Well that's why it doesn't look like it's faster but it's slower! They will keep doing this as opposed to solving the root of the problem by recoding the whole backup foundation as I'm suggesting from above. Backups will forever take longer and longer and longer and longer. That is what you have to look forward to. My guess is that they are not going to fix the foundation of how backups are done anytime soon having a good idea how they are doing this one. They would have to do a massive overhaul of the whole backup code, which basically they would have to admit that all the time coding this way was a waste and they see no profit from it and we deal with it just by pressing x sometimes. We can complain all we want, but for awhile if you don't want long backups, this is the real solution. What's funny is writing this email took much more time than figuring out what apple is doing, but I think this will help many apple iphone users. Let me know what you guys think.

Supposedly apple made backups slightly faster on 2.0.1, but like I said in my original posting above...it will get worse and worse because of the apps.
Just to verify and you could do this yourself. Right before you plug in to sync and it auto starts the backup process do this...go to the folder where all the files are as mentioned above, sort it by date modified. Add a refresh button on the toolbar. Then start the sync/backup, keep refreshing and you see the files getting updated. There are even temporary files apple's backup process creates that you don't see that keeps adding to a file, so even if you see one file updated, you might see it updated a few times until the whole backup for that file completes.
Here are my stats:
For me this time it took 27 minutes (earlier it took 2 minutes, but like i said with updates to apps, more apps, depending on types of apps, your computer speed, etc it will increase.
For me: In 27 minutes, it updated 1707 files with a total size of 82.8MB. There are a ton of computers that are much faster than mine that I'm sure would cut the minutes down. I have 6 pages of apps, but like I mention above, that doesn't matter because you could have one app that has 400 files with a large size. I would be interested in others posting their results, maybe in this format:
27min 1707files 82.8MB Pentium4HT Antivirus and other large programs running in background.
If you are interested you can even download program that will decrypt these files so you can view them in more detail...for mac, for instance, there is something like this: http://mac.softpedia.com/get/iPhone-Applications/Tools-Utilities/iPhone-Backup-D ecoder.shtml It allows you to backup and modify. It may help you decide what is taking your backups so long and you can decide if it's worth having that app installed versus not having a good backup. You can also pick out you sms backup file, contacts backup file, etc for those really interested in having backups of those specific files.
Hope this helps clear up things for everyone.

Why Backup database then backup archivelog from time...

Dear Experts,
I found in one of our rman scripts the 2 following statements:
backup database;
backup archivelog from time 'SYSDATE -8';
It seems to me that a "backup database plus archivelog;" is more simple/accurate instead of these 2 lines as the retention windows is defined (5 days) for this DB so rman will manage the retention of datafiles and archived log, isn't it ?
Why this separate statement for the archivelog ? I find it redondant but is it...
Any advice is as usual greatly appreciated.
Best Regards,
Guillaume

You are right. The use of backup database plus archivelog; is much better and you are sure that you backup all archived log you need.
Probably that is an old script, previous version or the responsable of this script didn't know RMAN so good and the option you posted.
Bye, Aron

Why backup gets corrupted?

I did a backup from my iphone and now i can't get it to the new one, it says its Corrupted, why it's that? i need to get all my pictures and sms

One thing to check is to be sure your new device has the vary latest version of IOS. If the old device had the latest version when the backup was made and the new one is even just one point version behind (new devices may sit on shelves a while and not get updated), then you can get a compatibility error.

Why backup to Time Machine doesn't work on Mavericks?

I upgraded to Maverics from Mountain Lion two weeks ago and I've experienced number of issues since then.
This time I have a problem with Time Machine backups. It has stopped creating backups since the upgrade to Maverics.
When I try to create backup I'm keep getting following message:
'The disk image "MyName Macbook Pro.sparsebundle" is in use
Try ejecting the disk image'
The problem is that Time Machine seems to be ejected. I checked that it is ejected properly both in Finder and Disk Utility.
Please could someoune possibly help me with the issue?

That's a known problem with AirPort Extreme and Time Capsule. If you have got any of these ones, restart your Mac and the AirPort Extreme or Time Capsule, and turn them on again, so you should be able to back up again.
Remember that Apple released a firmware update for them in order to fix this issue. Open AirPort Utility (in /Applications/Utilities) and follow the steps.
If you have got an external drive instead of the Time Capsule, disconnect it and connect it again

Why backup is so big ?

Hello!
     I've migrated some simple application from MySQL to Oracle XE. Application works fine, but backups created with backup.sh script are huge!
MySQL database backup was less than 2MB, but Oracle XE backup of the same database is about 1GB: 500 times more.
Is there any way to make smaller backups ? I need something simple like output from pg_dump or mysqldump.
best regards
Jarek

MySQL database backup was less than 2MB, but Oracle XE backup of the same database is about 1GB
I don't know if the two backups are comparable, but with backup.sh script you won't ever have a so small backup : it makes a full RMAN backup, and to reduce the backup size you have two choices :
1. Modify the script so that it does a compressed backup
2. Create your own script.
Said that I obviously prefer #2, if you want to modify the script, you can change all lines with "backup as backupset device type disk database;" to "backup as compressed backupset device type disk database;"
FYI, the difference, for my XE database, is as follows :
Normal :
-rw-r----- 1 oracle dba 790650880 6 lug 15:25 XE_07oe2pan_1_1.bck
-rw-r----- 1 oracle dba   9830400 6 lug 15:25 XE_08oe2pb6_1_1.bck
Compressed :
-rw-r----- 1 oracle dba 176455680 6 lug 15:32 XE_comp_09oe2pnl_1_1.bck
-rw-r----- 1 oracle dba   1097728 6 lug 15:32 XE_comp_0aoe2poo_1_1.bck

Why backup controlfile to trace doesn't produce the trace file in udump?

Hi there,
I recently redirected some of the data files on different drives. I started nomount with pfile and created new controlfile with the new datafile locations. I was able to open db and saw the new location of the db files. But when I trace the controlfile, I didn't see the trace file on the udump. Could anybody explain why?

also, when I did the show parameter I got the following results:
SQL> show parameter spfile
NAME TYPE VALUE
spfile string
SQL> show parameter pfile
NAME TYPE VALUE
spfile string
I did startup the db with pfile and open it with resetlogs. I created spfile from pfile. Why I'm not seeing the location of the pfile or spfile? Could you please help me understand this?

Why backup (dmp) restore at change in init.ora

i had change db_block_buffer and share_pool_size increase more in size
due to time saving at report retrive/process.
should i remove all tables and restore all table again.

rega.
pankaj ravalShould I use some strong words for your dba? Well, let me say this that increasing the memory and expecting the queries to be faster is rather a wrong approach to tune the queries. If you are saying that doing so gave you proper results you are sadly mistaken because when the memory would be full, you would again see the performance coming down and I can bet, you won't have the luxry to add memory as and when you would want. Second, you were asked what version of database you are running because the parameter, db_block_buffer has been deprecated since 9i onwards and you must be using db_cache_size . Depending on the version of the db(which you haven't shared with us) , most of the memory regarding parameters are now auto-tuned thus not requiring you to do anything about them and are also dynamic thus doesn't need to bounce the db as well.
HTH

Why backups fail despite ample disk space?

PROB: Backups fail. Not enough space. With Disk Utility, erased contents of 239.9 GB Maxtor. Still backups fail with 232.5 of 232.6 GB available.
QUES: Next step in troubleshooting backup failures.
TIA, Jim

I'm having the same problem. I have a 1 TB Time machine hard drive, and I have 761GB to back up.
I reformatted the Time machine hard drive. When I try to back up, I get a message: Backup failed. You have 961GB to back up and only 931GB available space.
That's too small.
First, while it varies greatly depending on how you use your Mac, Time Machine usually needs 2-3 times the space of the data it's backing-up, to be able to keep a reasonable "depth" of backups for you. See #1 in the FAQ per my previous post.
Second, a 1 TB Time Capsule has a total of about 930 GB when counted the way Leopard counts it, after formatting. If the message says it needs 961 GB after adding the 20%, it's trying to back up more like 800 GB. So you must have something else connected. Check the +Total included+ as in my previous post.
See #A1 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] for a handy widget that will display the backup messages from your logs. They'll show more of the detail.
You may be able to squeeze a backup onto your TC by excluding a lot of large things, so the total plus 20% doesn't exceed 931 GB. Then remove the exclusions and run another backup -- since the new amount to be backed-up will be much smaller, the 20% won't be as large, either, and it may fit.
Longer term, you need a much larger Time Machine volume.
Since you have an iMac, your best bet is to get a 2 TB external HD and connect it directly to your iMac. It will be much faster and more reliable, too.

Time Machine backup failure on 60Gb iPhoto Library on second partition

I had 1 partition on my Macbook Pro (2010). I have several users on the mac and I use fast switching for them. All users use same iPhoto Library and iTunes Media - they are situation in a separate folder in my partition root. My Time Capsule was setup to backup everything and it actually did it well.
Sometime ago I started to find a solution to avoid file permission problem - when different users add files/photos, they have permission to delete/change for them only. This caused some unwanted behavior. I read a lot of forums and basically the most appropriate solution is to create a separate partition on the same HDD and remove checkbox on it to support "Owner".
So I did it - created new partition. Then I moved iTunes and iPhoto to new partition and then I started backup again. Unfortunately, it failed. It took me 2 days to understand that it actually fails on iPhoto Library - all other staff works ok. But as soon as I allow to backup iPhoto Library, it starts backing up and shows some progress, but when 1-2 Gb (or sometimes 100-500 MB) complete it shows that "Backup failed - ... this might be temporary problem..".
I did not manage to resolve this - so I removed partition and reverted everything back by copying iTunes library and iPhoto library to external drive and then back after removing second partition. When I enabled backing up, everything worked great again - no problem.
So here is the question - why backup failed on iPhoto library when it was on second partition? Are the any ideas?

Move/backup/move back/backup did not fix the problem. TM still didn't backup the missing directories.
I was finally able to convince TM to do the right thing by following the procedure described here:
http://www.nzmac.com/quick-tips/time-machine/how-do-i-reset-time-machine.html
This isn't a solution because I still don't know what caused TM to think that it backed up something that it didn't back up. But the article was suggested by a friend of mine in IT who also owns a few Macs. After following the procedure and running TM again I can see all of the previously missing files backed up on the ext drive. I also used BackupLoupe (http://www.soma-zone.com/BackupLoupe/) to browse the files that were actually copied by the last backup. I see that TM copied the directories that I knew were missing and two other directories that I did not know were missing.
At this point I think my TM backup is complete. But now I'm on the lookout for a better backup solution. Until I find it I'll need to periodically compare backup sizes to make sure that TM keeps doing its job.

N900 and Backup on PC-Suite

When I click on "Backup" in PC-Suite it says:
"No phones are connected. Connect now."
However, all other applications in PC-Suite recognize my connected phone successfully. Can anyone please advise why Backup doesn't recognize it?
Thank you.

i haven't tried a back up with pc suite but i do know that the N900 isn't fully supported so what i do is sync the contacts then in mass storage mode i copy all music, video, documents... anything i want to protect to a file on the pc. i don't think you can back up any messages or settings tho

I have a blue box on screen headed ICloud Backup.

It states Ipad not backed up for two weeks.
Pressing the OK buutton in this box gets no response and I cannot access the Ipad screen.
The device is in use daily, so no idea why backups not happened.
