Backup taking days together

Hello Everyone..
Let suppose, a backup process is used to get completed in 2 hours.
All of a sudden, if it is taking days together to be completed, what might be the reasons?
Thanks and Regards, Junior SQL Server DBA, Miracle Software systems, Inc.

Hi,
Further of Shanky and Saeid posts, and as mentioned, we need much more information in order to point the finger on the specific problem. I do agree with Shanky that locks and waits will not be my first monitoring operation (it will come later on). We can
try to throw some idea of what can be the problem for several ays without more information. So I will add some ideas till we will have more information.
* Check the Machine general performance (CPU, Memory, Disk IO, etc), especially if you are using compress check the CPU (check the time/cpu without compress).
* check for waits and locks
* Check for too many VLF in the log file
* Check How big is your log file and how much of it is in use
* Check if the bottleneck is on the write speed. You can check it using Backup to nul (ont forget to use WITH COPY_ONLY)
As I mentioned this is only some points need to be checked/change... there is much more on this subject :-)
I will try to write a short blog maybe on this issu
I hope this is helpful :-)

10.5.5 Initial backup is taking DAYS (!!) over firewire 400

I ran into an issue where I had to erase my Time Machine backups on my external FW400 OWC Neptune backup drive. Not a big deal as I also use Superduper for bootable backups.
so last week I tried doing a new initial backup and it's taking days literally to get just under half done. Did 10.5.5 fry firewire somehow? up until now I had normal firewire 400 speed.
my work machine is 10.5.5 MDD dual 867 G4, 200/80 GB drives, 2 GB RAM backing up to an OWC Neptune FW400 drive with 500 GB drive partitioned as 350 and 114 gb paritions.
I tried running Disk Utility and found no errors, I repaired permissions for good measure
Any thoughts?

Ok I ran Diskwarrior 4.1 on the G4 and fixed a few minor errors
I then ran it on my backup partition (the 350 GB partition of the Neptune drive)
I got speed inhibited by disk malfunction error followed by the number. I've used DW enough to know that that that's not good.
Just for kicks I ran DW on the 114 GB partition of the Neptune drive and it reported no problems. Does that mean it's not a hardware failure????
I then rebooted the G4 and attached the drive via firewire 400 to my mid 2007 MacBook Pro and ran disk utility (my thoughts were it might be bad firewire ports on the G4. I have the standard 2 plus 4 more on a PCI card).
Disk utility reported no errors.
Now I am using DW to check the files and folders on the backup drive for problems....

Preparing Backup for Days!

My Time Capsule has been in "preparing backup" mode for three days now. I've had the Time Capsule for over a year and haven't had problems with it before. It's only been 16 days since my last backup so it's not as if a lot has changed in terms of what it's backing up. I've tried resetting the Time Capsule (unplugging and plugging back in) and resetting in the preferences, but it's still taking days to prepare backup whereas before preparing for backup only took a couple of hours at most. Do I just need to let it run its course no matter how long it takes or is there something I can do to fix this issue?

that's not giving enough !
this is an example of mine:
+Starting standard backup+
+Mounted network destination using URL: afp://user%[email protected]/Data+
+Backup destination mounted at path: /Volumes/Data+
+Disk image /Volumes/Data/MISSION CONTROL_00145119d47e.sparsebundle mounted at: /Volumes/Backup of MISSION CONTROL+
+Backing up to: /Volumes/Backup of MISSION CONTROL/Backups.backupdb+
+No pre-backup thinning needed: 354.3 MB requested (including padding), 259.26 GB available+
+Copied 503 files (6.0 MB) from volume POWERBOOK.+
+No pre-backup thinning needed: 347.0 MB requested (including padding), 259.26 GB available+
+Copied 397 files (0 bytes) from volume POWERBOOK.+
+Starting post-backup thinning+
+Deleted backup /Volumes/Backup of MISSION CONTROL/Backups.backupdb/MISSION CONTROL/2009-10-17-204514: 259.26 GB now available+
+Post-back up thinning complete: 1 expired backups removed+
+Backup completed successfully.+
+Ejected Time Machine disk image.+
+Ejected Time Machine network volume.+
i expect you stopped the back up process. let it run a bitter longer, maybe even over night.
i recommend you connect yout TC to your Mac by ethernet cable (set your Mac not to sleep !)
let's have TM buddy's comments afterwards

My new iphone 6 plus has been restoring from iCloud backup for days. I do not have all my apps or music yet

my new iphone 6 plus has been restoring from iCloud backup for days. I do not have all my apps or music yet. How do I fix it?

Hello Bernharp,
Thank you for participating in the Apple Support Communities.
It sounds like your iPhone 6 Plus is taking a long time to restore from an iCloud backup. I can understand why you'd be concerned after several days of waiting.
This might happen if your backup contains a lot of content such as pictures or your Wi-Fi connection isn't consistent.
If the restore still hasn't completed, take a look at the information in the "Restoring my device from an iCloud backup is taking a long time" and "A message says restore incomplete or some items could not be restored" sections of this Support article:
If you need help restoring from an iCloud backup - Apple Support
Sincerely,
Jeremy

Rman backup taking daytime

Hi
I would like to take the full rman backup of the production database during the business time ( during day)
Is it reduce the performance of the database? if yes please provide the justification or any docs or any link

Hi,
Impact is due to high I/O during backup. It your prod server have enough juice left to take care of increased I/O , then you can take RMAN backup during day time. It is all about your priority. Mostly backup is done during off hours so that Prod users are not impacted due to high disk I/O.
Regards

TS4062 I lost all of my contacts and notes when attempting to move over music. When I try to restore the backup the day I want to restore to is not present. I do see a copy on my I cloud but I can't seem to retrieve it. What can I do?

IPad is taking DAYS to download apps

iPad taking days (plural--DAYS!) to download apps, though storage is nowhere near full and the apps are simple free games for the kids. Never had any issues with updates or downloads before, and can't find any info about this. Help!

1. Check if there is any stalled download in iTune e.g. Podcast, Music or Movies
2. Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
3. Make sure you are connected to the internet

1TB Time Capsule taking days for backup of 2GB

So, I know this may be an absolutely idiotic question, but I'll ask it anyway. I have a 1TB Time Capsule that is less than a year old. I've been able to perform initial backups of large amounts in the past pretty decently, but a few months ago, I quit backing up to it, but left all of the data there. I recently found out that the hard drive on my first Macbook Pro (also less than a year old) is dying, and I'm trying to put all of the essentials on the Time Capsule so the backup will be there. The essentials total to about 2.4 GB, and I have waited two days, not doing anything on or to the computer and it has gotten to only 14 MB, not to mention it took hours to just "Prepare". I have the latest firmware and all of the most recent (as of 4 July 2009) updates. This seems a bit off to me, and I'm just trying to figure out if there's anything wrong, so I can send it in before my warranty expires on the 29th. I've already gotten the short end of the stick as the warranty for my laptop was expired less than one week ago, meaning I'm going to have to pay for installation and a new hard drive, and I don't want to get short ended like that again. Do ya'll think there could be an actual problem here, or could it just be something on my end? If so, what could it be? Thanks in advance for any help ya'll can give.

Two things to try.
First off... before you try and backup from the MacBook Pro to the TC, delete the original backup from the TC.
Secondly, the problem might be due to the fact that since the MacBook Pro hard drive is failing, the system is taking a long time in retrying to read data blocks off the disk. One way to check this would be to use Carbon Copy cloner or similar to take a backup image of the MacBook Pro hard drive onto the TC.

Time Machine backup taking too long (91 days)

I'm doing the initial TM backup to a partitioned EHD... TM has been running for 3 hours and it has made almost no progress. It even has the estimated time as 91 days (!!!) to complete the backup. Is this normal? The very first time I did TM (on another drive) I remember it took a while but surely not 91 days. Am I doing something wrong? Or do I just need to wait it out and let this take its sweet time?

Hello Jossydtaylor

RMAN cold backup taking more time than usual

Hi everybody.. please help me resolving below issue..
I have configured the RMAN in one of the production database with separate catalogue database six months earlier. I have sceduled weekly cold backup through RMAN on sunday 6pm. Normally it used to take one hour to complete the cold backup and database goes down soon as the job starts.
But since from then every week the time taken to just initiate the database shutdown continuosly increasing and recently when i checked it is taking 1 hour to initiate the database shutdown. Once the initiation starts it hardly take 1 to 3 min to shutdown.
Database is up and running during that one Hour. I was in the assumption that RMAN takes some time to execute its internal packages.
Please help
Regards,
Arun Kumar

Hi John and Tychos,
Thank you very much for your valuable inputs.
Yesterday there was cold backup and i have monitored the CPU usage. But there was no load on the CPU at that time and CPU usage was 0%
I have tried connecting to RMAN manually and it connects within a second. And also noticed in prstat -a that rman connects as soon as the job starts.
So i think that its taking time at the deleting obsolete backups.
But I have observerd following observation.
Before executing the delete obsolete command as mentioned before
RMAN> REPORT OBSOLETE RECOVERY WINDOW OF 35 DAYS DEVICE TYPE 'SBT_TAPE';
Report of obsolete backups and copies
Type Key Completion Time Filename/Handle
Backup Set 83409 25-JUL-09
Backup Piece 83587 25-JUL-09 arc_SID_20090725_557_1
Backup Set 83410 25-JUL-09

Backup Set 83411 25-JUL-09
Backup Piece 83589 25-JUL-09 arc_SID_20090725_559_1
After executing the delete obsolete command
RMAN> REPORT OBSOLETE RECOVERY WINDOW OF 35 DAYS DEVICE TYPE 'SBT_TAPE';
Report of obsolete backups and copies
Type Key Completion Time Filename/Handle
Backup Set 83409 25-JUL-09

Backup Set 83411 25-JUL-09
Backup Piece 83589 25-JUL-09 arc_SID_20090725_559_1
Please advice me on the following.
1. Why its not deleting the obsolete BACKUP SETS?
2. Is it normal that RMAN takes this much deleting obsolete backup sets? How can i minimize the time taking for deleting obsolete files.
Thanks and Regards,
Arun Kumar

Time machine taking days...

Hello! New in this of mac computers. I got my Macbook air new version, and the time machine is taking forever (now it is saying around 19 days, and evolving from 10 MB to 10 MB every half an hour. The hard drive is a Lacie with USB 3.0, and not sure why it is taking such a long time... Any advice? (There are like 50 gb in my hard drive, and I have not updated to Mountain Lion...)

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter the word "Starting" (without the quotes) in the String Matching text field. You should now see log messages with the words "Starting * backup," where * represents any of the words "automatic," "manual," or "standard." Note the timestamp of the last such message. Clear the text field and scroll back in the log to that time. Post the messages timestamped from then until the end of the backup, or the end of the log if that's not clear.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don't post many repetitions of the same message.
When posting a log extract, be selective. Don't post more than is requested.

Backup taking a LONG time, excruciating

Hello,
I'm using Time Machine to backup my MBP to a Time Capsule disk, and it is taking absolutely forever.
It started at 7:30 this morning, doing that "deep traversal" thing, and then started copying files at around 9:15. Now, at 12:00, it has gotten all the way up to "609 KB of 46.2 GB". I have excluded the backup disk from Spotlight indexing.
Does anyone have any idea what is going on?
Thanks...

The "deep traversal" thing means that TM isn't sure that what's on your internal HD matches it's records. So it has to look at every file and folder on your system, and compare them to what's on your TM backups just to figure out what needs to be backed-up. That's a long process on a F/W 800 disk; but, as you see, excruciating on a TC.
As NeroWolfe says, plugging your TC directly to your Mac with the Ethernet cable can speed this up greatly.
The "deep traversal" can be caused by several things. The usual suspects are an improper shutdown (which can also corrupt data on your internal HD), certain hardware repairs, a full restore, or going several days without a successful backup.
If you see this when you think you shouldn't, you need to post back and investigate the cause.
By the way, you should also exclude your TM disk from any anti-virus scanning.

Time Machine makes several huge backups a day

Hi,
I backup my Macbook Pro wirelessly with Time Machine to my Time Capsule.
This has been working great for about a year now. However since a week or so it keeps making these huge backups several times a day.
And by huge I mean 50GB+. I have tried D4 on the troubleshooting page but it did not work.
Any help would be greatly apreciated!
Specs:
- Macbook Pro 15" 2,53GHz Intel Core 2 Duo 4GB 1067 MHz DDR3
- Running Mac OS X Snow Leopard 10.6.8
- Time Capsule 802.11n

@Pondini: Well once I completed the steps and Time Machine was fully configured again, it went right back to the 59GB backup it kept doing before.
Are we taking about the same #D4 (in Time Machine - Troubleshooting)?
It has a number of common causes of extra-large backups, and links to #A2, which has a couple of apps that will show you just what's getting backed-up, so you can take corrective action.

(Restoring) backup taking forever

Hi,
I've a big problem with my iPhone 4 and iTunes. I've read discussion on a similar problem, without finding an answer that could work with me.
Today I tried to sync my iPhone 4 (iOS 5) via iTunes/cable. The backup phase was lasting forever. I tried to stop it after a couple hours, but iTunes refuses to stop. I quitted it, but it refuses to quit. I forced quit it. As a consequence, the communication icon on the iPhone disappeared.
I tried the above more times, until the point when the iPhone was no longer recognized by iTunes, and refuses to show any other than the iTunes icon, together with an USB cable.
Trying to restore data was unsuccesfull for several tries. iTunes told me that it was impossibile to restore. A link to the Apple site for more information resulted in an empty page.
After a while I tried again. This time, restoring the iPhone and keeping it to the original state worked. At this point, restoring my latest backup began. It is still going on, and on, and one hour a half has passed, with iTunes saying it is calculating the remaining time, and the iPhone saying restore is going on.
Do you have any idea? The technician at the Apple support had no idea of what was happening. I've no idea as well, and am waiting with my phone doing nothing, and no message or change conforting me things have not frozen.
Thank you,
Paolo

It didn't work: the restore time was growing (it reached 18 hours!), and was not moving.
So, I decided to reboot everything, and start fresh, with no backup. This time it worked, but I had to spend the afternoon reinstalling everything.
I'm not too happy of what happened, in particular because there is no explicaton for it.
Paolo
