Backup very slow

i want to do a full backup first time. i have a extrernal drive with 1 TB with 4 partitions. i configures time machine so that all folders should be saved.
in the first hour time machine saved only 10 GB. the external drive is quiet,so i think the drive has nothing to work.
is it sensible to backup all folder (like system, system folders). can i find a usefull documentation for timemachine.
whats about performace. is there any software which is better than TM?
thanks for answering. (My english is bad - German)

Have a look at [this Apple article|http://support.apple.com/kb/TS1550] (is your external using Master Boot Record?).

TM is good in its simplicity, but it doesn't offer a permanent backup solution as it will eventually purge older backups as space gets scarce. There are lots of other backup utilities out there. Some use TM and compliment it with [SuperDuper|http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html], [Carbon Copy Cloner|http://www.bombich.com/software/index.html] and other similar cloning utilities. Others use [Retrospect|http://www.retrospect.com/products/software/retroformac>.
It all depends on how you set up your backup routines, which depends on who you use your computer and for what. Google for instance for "backup strategy" or the like.

4Th Generation Time Capsule Running Backup very Slow

I am having a problem with my 4th generation time capsule as it is running very slow , it shows that i need to backup 151 Gb data and for the last 2 days the device backup only 150 mb, pls advise what is the problem? setup of the wireless network seems fine to me without any problem
please help

When you use ethernet, make sure your wireless is turned off in the computer.
It can be worthwhile isolating the TC to the Computer so there is nothing else happening.
Also for Mavericks ensure you have ipv6 set correctly to link-local.
A 100GB backup certainly should not take 20hours..
Although the 2008 (gen1 TC is much slower than later versions).
A first backup of the computer must deal with loads and loads of little files, as a warning can go slow.
A different backup software will be just the same.. it is the speed over network and handling small files that is the issue. Once that first backup is done the later incrementals should not be a problem though.

Time Machine backup very slow in Lion

After installing Lion Time Machine backup (not initial one which is long by default) takes about 40 minutes vs. about 5 minutes in Snow Leopard. Very annoying because it slows down my entire system for such a long time. Any help, please?

Here is a log copied from Time Machine Buddy:
Starting standard backup
Backing up to: /Volumes/Time Machine/Backups.backupdb
2.20 GB required (including padding), 126.68 GB available
Copied 394 files (0 bytes) from volume Pete 02.

Copied 158965 files (90 KB) from volume Pete 01.
Starting post-backup thinning
No post-back up thinning needed: no expired backups exist
Backup completed successfully.
No additional messages, perfect backup, no need for thinning and it took 45 minutes, almost 10 times slower then in Snow Leopard (same TM preferences, exclusions etc).

Time Machine backup very slow on WD My Book For Mac external HD

I have been using a Western Digital 1 TB external HD (My Book For Mac) to backup my data today for the first time, using their SmartWare software. Everything went smoothly, I backed up 91 GB of data in 2-3 hours.
At the same time, I have also Time Machine activated, which started backing up my files a while ago, but it is crawling at 8 MB per minute. A quick calculation tells me it will take 180 hours to back up 90 GB (?).
I have 2 questions:
1. Are SmartWare and TimeMachine supposed to be run exclusive of each other?
2. If I just ran TimeMachine, why is it so slow? I use a USB 2.0 connection that worked fine for the My Book's own software.
Thanks for your help!

You should first repartition and format the drive. Most likely it is setup for use on Windows. Try this:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Do not use the WD software. If it's you wish to create a bootable backup of your drive as well as keep a TM backup, then you should create two partitions on the drive. One for your non-TM backup and one for TM. For the bootable backup use third-party software such as SuperDuper!, Carbon Copy Cloner, or SilverKeeper - Download at VersionTracker or MacUpdate.
Note that many WD drive systems cannot be used for bootable backups. You can find information related to this at the WD web site.

RMAN BACKUP VERY SLOW

Hi all,
what is fastest method to take backup using rman
Thanks&Regards,
Mahesh

Hi Mahee,
Can you be little bit precise on you question?
1. Is it you are planning to take backups using RMAN or your scheduled backups are running slow on RMAN?
2. Please specify the type of backup.
I would first check with the network throughput and native transfer rate and compare them with the backup speed.
Also, tuning would largely depend on if you are using Synchronous and Asynchronous Disk I/O and thus enabling the db parameters for the same.
While the job is running, execute a script containing the following SQL statement to know the status of the RMAN job:
SELECT sid, serial#, context, sofar, totalwork,
round(sofar/totalwork*100,2) "% Complete"
FROM v$session_longops
WHERE opname LIKE 'RMAN%'
AND opname NOT LIKE '%aggregate%'
AND totalwork != 0
AND sofar <> totalwork
If you repeat the query while the backup progresses, then you see output such as the
following:
SQL> @status
SID SERIAL# CONTEXT SOFAR TOTALWORK % Complete
8 19 1 10377 36617 28.34
SQL> @status
SID SERIAL# CONTEXT SOFAR TOTALWORK % Complete
8 19 1 21513 36617 58.75

RMAN: Increment backup very slow

Hi All,
We have Datawarehouse database having size around 7TB. Increment backup performance is extremely poor it is taking approx 14hrs to complete the process. We have also enabled block change tracking but failed to meet target.
Below mentioned DB info & RMAN configuration parameters:

Thanks in advance.

Thnaks for reply.
Have you configured Compressed backups?
--> Yes. with below command.
RMAN> backup as compressed backupset incremental level 1 tag=$v_tag database;
Have you allocated channels ?
--> Yes.
allocate channel backup_disk1 type disk format '$v_bdest/%U' maxpiecesize 10G;
allocate channel backup_disk2 type disk format '$v_bdest/%U' maxpiecesize 10G;
allocate channel backup_disk3 type disk format '$v_bdest/%U' maxpiecesize 10G;
allocate channel backup_disk4 type disk format '$v_bdest/%U' maxpiecesize 10G;
allocate channel backup_disk5 type disk format '$v_bdest/%U' maxpiecesize 10G;
What is the Large pool size configured? try to increase.
--> large_pool_size=1073741824
Is backup to DISK or TAPE? mentioned in script?
--> Backup goes to DISK only.
How is DISK performance?
--> How can we calculate DISK performance on LINUX?

Time Capsule VERY slow ethernet back-up on my iMac

Hi anyone who can help....I'm getting really frustrated with Time machine
It seems quite afew people are experiencing problems with TC....
BUT they all seem to have different issues. Mine is simple.
As a wireless network it works just fine, last weekend i had some friends over and we had 4 laptops going at once - speed was fine
Backing up - My G4 powerbook works FLAWLESSLY, backing up wirelessly.
BUT...My G4 iMac (connected directly via ethernet cable) hasn't been able to do a back-up since got it. It gets stuck on preparing or takes day's (Yep DAY's) to do a few 100 MB.....
Obvoiusly the TC is working, but not the wired connection. I can't try my iMac wirelessly, as it doesn't have an airport card
ANY suggestions? Oh and I don't have any virus software installed

Andrew,
*_Slow Time Capsule Transfer Via Ethernet_*
*Disable Anti-Virus Software*
“Using virus scanning software can make Time Machine backups very slow. If you use Norton Antivirus 10 AutoProtect or a similar product, try turning it off during backups.” [http://docs.info.apple.com/article.html?path=Mac/10.5/en/15140.html]
*Create An “Ethernet Only” Location*
While you are physically connected to the Time Capsule via ethernet you may still be experiencing slow data transfer speeds because your Airport network is still active and taking priority.
Connect one end of a Cat-5 Ethernet cable into one of the LAN ports of the TC (<•••>) NOT to the WAN port (wheel icon). Connect the other end to your Macs ethernet port.
Next, go to System Prefs --> Network.
At the top of the window note what “Location” you are currently using, as you will need to return to this setting later.
Now, change “Location” to “Edit Locations”.
Click the “+” button and create a new location named “Ethernet Only”.
Click “Done”.
In the Services Pane on the left, eliminate all other services using the “-” button leaving “Ethernet” only. If you choose to leave other services listed then al the very least move Ethernet to the top of the list using the Action Menu (gear button) at the bottom and "Set Service Order".
Verify that “Configure” says “Using DHCP”.
Click "Apply" in the lower right.
You should be seeing an assigned IP Address and the Status should say “Connected”. The dot beside “Ethernet” should be green.
Now begin your backup or transfer of files.
You should still have internet access during this period.
Once the backup/transfer is complete, remember to change the Network Prefs “Location” back to “Automatic”, or whatever setting it had originally been, to restore Airport connectivity.
*Adjust Ethernet Speed*
Open Network Preferences.
With Built-in Ethernet selected on the left, click "Advanced" in the lower right.
Click "Ethernet" tab on the far right.
What is selected beside "Speed"?
Try changing this setting and see if it makes a difference.
Next launch Airport Utility.
Select the Time Capsule on the left.
Click “Manual Setup”.
Select “Internet” from the toolbar.
Click “Internet Connection” tab.
Near the bottom verify that “Ethernet WAN Port” is not set to a slower speed. Either choose “Automatic” or the fasted speed available.
If you have made any changes, click “Update”. 
*Slow Full Backup After Restore*
Try either deleting the “old” backup disk image or copying it to another disk. Then start the “new” full backup again. Some users have experienced improved speed when the “old” disk image was removed from the backup disk.
Let us know if this was helpful.
Cheers!

VERY slow backup to external Hard Drive

I have an older external HD case (New Motion) with a Western Digital 120GB Hard Drive that I use for backup, firewire only.
I use this drive on my old slot loading iMac G3 (10.3.8) and it runs very fast, copying 16GB from the iMac to the backupin about 15 minutes.
When I connect the backup drive to my G5 iMac (10.4.2) it runs VERY slow at night, taking 6 hours to copy the same amout of information.
I notice that during the day it takes less time, but still about 1.5 hours. (The night/day differences are consistent).
Is this an issue with Tiger or a setting in Tiger or how Tiger talks to firewire, or an issues with the G5 iMac? (Both firewire ports work fine with my iPod updating music).

Hi robfromkinglake west,
Try and isolate the issue. Check if it's only with this drive.

Time machine backup is very slow after migration to Mountain Lion

After I migrated to mountain lion, Time machine backup is very slow. Time machine preference says there is no previous back up although I had Time machine on before migration. It did not help verymuch to connect an ethernet cable between my timecapsule and my Macbook Pro
Here are the screenshots I see:
Should I erase the previous backup made on Lion before backing up on Mountain lion? in this case how do I transfer the Lion backup file on another disk just in case something goes wrong before I have a good backup under Mountain Lion? just like any other file?

After further reading on the forum, the problem was solved: I used the possibility to back up on a second disk (in the preferences Time Machine choose a disk and save on both disks) to make a back up on another usb disk, and then erased the old .sparsebundle file on my Time Capsule. I have then re defined time capsule as the back up disk and then the backup was muuuuuch faster (one night instead of less than 1 giga after 3 days.....)

When i start my hot backup my database getting very slow

Hi,
I am using following commands for enabling hot backup
SQL>ALTER SYSTEM ARCHIVE LOG CURRENT;
SQL>ARCHIVE LOG LIST;
SQL >ALTER DABATBASE BEGIN BACKUP;
Database altered.
SQL>SELECT FILE#,STATUS FROM V$BACKUP;
FILE# STATUS
1 ACTIVE
2 ACTIVE
3 ACTIVE
4 ACTIVE
and using cp -rp command to copy the file (backup copying speed good) but database performance very slow
How to improve performance ...
Regards

RMAN doesn't need that at all - much less redo - and also archive - generation then.
Furthermore, you can use BACKUP AS COMPRESSED BACKUPSET DATABASE to decrease the size of the backup even more - if space is an issue.
In short: Use RMAN :-)
Agree with that! Unless the copy is actually going to an NFS mount or something, where I would be concerned whether it is the type of NFS that Oracle likes. I'd also advise a current patch set, as the OP didn't tell us the exact version, and I have this nagging unfocused memory of some compression problems of the "oh, I can't recover" variety.
I'd like to see some evidence on I/O and cpu usage before giving advice. When I used to copy files like this, it would choke out everyone else. RMAN was a savior, but had to wait for local SAN upgrade.

Backup to TimeMachine with WI FI is very slow!

Yes, WIFI is slow. If this is your first backup, it will be much faster if you connect to your Time Capsule or Airport Express via an Ethernet Cable.
Also try the things in item #D2 of the Time Machine - Troubleshooting *User Tip* at the top of this forum.

Very Slow Backup

I have a 500 GB USB hard drive that I can move files to very quickly. When I select it as my Time Machine Hard Drive the the backup runs very slow. According to the tracking bar it's only backing up about 100 MB every 2 min + I stopped spotlight from indexing the drive but it didn't make a noticeable difference. The drive is currently formated Extended but I've tried Extended (Journaled) also. The backup seems to be working and I have not seen a large performance hit. It just seems to be very slow.
Does anyone have an idea what I could have wrong?
Thanks

You probably are not in any danger. The first TM backup has huge amounts of things to do beside just copying your boot volumes data. It builds a data base and collects a bunch of other info to keep track of things.
How much data does Time Machine pref panel show it has to backup ?
Let's say it's 150 GB. Then a USB2 device will get on average around 12 MB/sec. That's some 43 GB per hour. Thus for 150 GB the backup will take 3.5 hrs.
Be patient and let TM backup finish.
Are you see a rotating set of arrows in the Finder side bar to right of your TM backup USB device ? Also, there could be a small backup status window floating about somewhere that shows the backup progress as well.

When I connect an external hard drive to macbook pro it is very slow to appear on the desktop and Finder window, sometimes 20 mins or more, even with auto backup switched off . any clues?

External USB HD is very slow during SuperDuper backup

I am using an external USB harddisk to backup my iMac. I have formated the disk with a Mac OS X file system and it mounts without any fault.
I am using SuperDuper to copy all my files from my internal to the external harddisk. The throughout I get is something between 11-13 MB/s. This is very slow for USB spec that could be up to 40-50 MB/s.
Anybody has any idea what's going on here how i can improve this speed?

Hi aschmid,
the reported throughput of SuperDuper is largely depending on what files are backuped.
Large files usually backup faster than smaller ones.
Just for comparison, backup of approx. 48GB system volume :
MacPro - internal disc to internal disc = about 18 minutes
MacPro - internal to external FireWire 800 = about 25 minutes
iMac - internal to external FireWire400 = about 55 minutes
(The duration are rough, coming from my memory).

Backup to the remote stages is very slow

Hello!
I am facing with the following problem for DB Backup to the remote stage.
If I plan the ALL ONLINE-Backup, then the backup is takes very slow, backups two or more files and aborts.
I have checked the appropriate BTC WP and saw that the WP is holding/waitng.
The reason is RFC.
How can the problem be solved?
Thank you very much!
regards
Thom

Without logs of the backups we can just guess, what is wrong.
Post the log of a failed remote backup here and let´s see then.
