DB read_only backup size increase

Hi Experts,
Have below 3 queries. Kindly enough throw some light
1) I have 1 database which is read_only. tlog backup size daily fluctuates how this is possible please...
2)another question related to another problem
backupset table of 1 database shows 65 MB full readonly database backup(named: abcd) daily. here i am somply taking backup from litespeed.
when i run backup database abcd to disk="c:\abcd.bak" with copy_only,checksum,init (in read only mode) it shows size of 57 MB only. Why there's gap as database is in read_only mode.
3) buffercount and maxtransfersize are safe if i have x64bit machine and 100 GB RAM. restore verify completed successfully.
Regards
Manish

1) Why are you taking a backup of a read only database every day ?
Since nothing is changing just stick with the backup you already have. As for fluctuations you may be taking a backup that's added on the latest backup so it'll increase over time.
2) There is no direct correspondence between size in BAK and MDF/LDF. You could have compressed tables or compressed backup, empty space etc etc
3) Changing buffercount and maxtransfersize are safe to change. But first measure for what you gain from changing them since increasing them will have a higher impact on cpu time.
Here are some benchmarks on those:

Big increase in backup size after upgrade

Hello
I've upgraded my database from 10.2.0.4 SE on win2003-SP2 to 11.2.0.1.0 SE on win2008-R2-SP1 64-bit, by doing exp/imp
The databasefiles size sums up to about 150gb on each server
But when I do a normal RMAN database backup of the datafiles on the new database (backup device type disk database;) I get a backupset that is 78 gb in size .
On the old database the backup size was only 36 gb
The data in the two database is about the same, and I dont believe I'm using compression on any of the database backups. I've listet the RMAN paramaters below
Can anybody tell me why I'm seeing this huge increase in backup size?
Best regards
Klaus Mogensen

Backup size is increased after resync catalog

Hi everyone,
I have describe my problem, if anyone have a solution please provide me.
Rman catalog database version : 10.2.0.1.0, OS : red hat linux
Target database version : 10.2.0.5.0, OS : solaris 10
rman catalog database space is full, then i move my example tablespace to another location, but i forgot to change the ownership of new file.
And I have no backup of my rman catalog database. so i offline the datafile first for opening the rman catalog database after opening the database I have offline the whole example tablespace and this tablespace cannot contain any thing related the catalog.
after that I used the command : crosscheck archivelog all;
DELETE EXPIRED ARCHIVELOG ALL
then i run the command : CROSSCHECK BACKUP;
DELETE EXPIRED BACKUP;
then i run the command : report obsolete;
delete obsolete;
then i run the command : RESYNC CATALOG;
then i run the command : change archivelog all validate;
after doing all the thing when I am taking a backup of archive log by using following command :
run {allocate channel c1 device type disk format '/appl2/prodback_rman/prod_fullbackup/ARCH_%d_%s.bak';
backup archivelog all;
before performing all the above thing my archive backup of whole day is around 5gb but after the above thing my archive backup of one day is around : 126gb
and my level0 backup is alright after and before the above thing and the size is around : 139gb
the script for the full backup is :
run {allocate channel c1 device type disk format '/appl2/prodback_rman/prod_fullbackup/FULL_%d_%s_%c.bak';
backup incremental level 0 database skip offline;
after that I have perform the incremental level 1 backup by using the following script :
run {allocate channel c1 device type disk format '/appl2/prodback_rman/prod_fullbackup/INC1_%d_%s_%c.bak';
backup incremental level 1 database;
before the above activity the size of incremental backup is around : 4.5gb but after performing the above activity the incremental backup size is around : 120gb
it is very critical for me, if any one have the solution please provide me as early as possible.
Thanks & Regards

Hi Hemant K Chitale,
you said that I am using the COMPRESSED BACKUPSETs till 22-Jan, so I am posting
the rman configuration here that is used before all this happening and same
configuration is used right now.
but before resync catalog the archivelog is generated only one location then I used to archive log
dest for archive log generation then after 5 month I will resync my catalog. may be it is the
reason.
because there are no compressed backupset is defined in the rman configuration.

right know the archive log backup size by rman is around 19gb per day.
so tell me how we reduce the size of my archive log backup according to
my rman configuration and how can i reduce the archive log generation on
my production server on daily basis.

Time Machine backup size has doubled since updating to iMovie 10.0

So since installing Mavericks and running iMovie 10.0, the size of my Time Machine backup has increased enormously.
It seems clear that Time Machine is backing up my iMovie content twice, that is seeing the old iMovie Events and iMovie Projects folders (which are still present in my Movies folder), and the new iMovie Library package, as separate things even though they cannot be separate as they are not taking up any more space on the disk.
The backup is also taking much longer than usual, though I'm not so worried about that.
Any ideas about the cause or how to fix this?
I'm running Mavericks on a late 2008 MacBook 2.4 GHz Unibody with 8GB RAM and 250GB SSD, backing up to Time Capsule with 2TB hard drive

What I have found so far is that when upgrading to iMovie 10 there is a conversion/duplication process that takes place in order to make your iMovie 9 events compatible with iMovie 10.
They should be nearly identical in size. You can confirm this by right clicking the "iMovie Events" folder (iMovie 9) and the "iMovie Library" package (iMovie 10) and selecting "Get Info" and their respective sizes should be nearly identical. The reason for this is unclear other than you retain the ability to run iMovie 9 which will continue to access the "iMovie Events" folder. iMovie 10 will access the newly created/duplicated "iMovie Library" package. Any new video you add using iMovie 10 will also be stored in the new "iMovie Library".
If you want to see the contents of the "iMovie Library" then right click and select "Show Package Contents". You should see all the folders (events) you created originally in iMovie 9.
At some point I presume you have the option to delete the "iMovie Events" folder if iMovie 9 will no longer be utilized or, better yet, back it up on a separate drive if like me you don't like deleting files until you're absolutely sure you don't need them. Otherwise, from what I have found, you are in fact backing up two sets of files.
For now I had to exclude the "iMovie Events" folder from my Time Machine backup because, like you, my back up nearly doubled in size (videos take up a lot of space) otherwise I got an error message from Time Machine indicating that my external drive did not have enough space for the backup file.

Backup Size always = 2.0 GB

Does anyone have the issue that in Storage & Backup, where it says, "Backup Size" the backup size is ALWAYS = 2GB, even though "Next Backup Size" & my phone listed under "Backups" is listed as 3.8GB. Anyone else have this issue?

Its probably from past backups.
I believe that where it says "Backup Size", its referring to the last backup you did on your phone.
"next backup size" is greater because you increased the data on your phone since then.
I had it off on my phone but just turned it on to check.
It says Backup Size 0 bytes, and Next backup size 2.3GB.
Hope that clears up your problem
Edit: You can also just delete your old backup or overwrite the existing one to save space.

I am trying to update my time machine backup on time capsule, but time machine keeps trying to create an entirely new backup (evidenced by the 200GB backup size). How can I get time machine to modify my old backup rather than create a new one?

It must have found the old backup corrupt.. so you will more than likely have little choice. You can archive off the old backup if it is still useful.
You can also verify it. See A5 http://pondini.org/TM/Troubleshooting.html
He also has some info on this problem. eg C13.

Backup size says 2.0 GB, but I have all backup options turned off. Why is my backup size still 2.0 GB?

I had an iPhone 4 updated to the iOS 7.1.2 version, and I recently purchased an iPhone 5s. When I got the 5s, I transferred all of my camera roll pictures from my 4 to my PC in a file folder and deleted all the photos from my 4 camera roll. I also turned off the "camera roll" backup option in my iCloud storage settings. However, my backup size still said I had a large backup size, so I turned off all the apps in the backup options under the iCloud storage tab. Along with all the apps, I turned off the backup for the Mail, Contacts, Calendars, Reminders, etc. Yet, my backup size on my 4 still said 2.0 GB, and my 5s needs more backup storage without purchasing any extra storage.
I'm not sure if I should completely delete my 4 backup or if there is a solution without completely deleting its backup. If there is a possible solution to decrease my backup size without deleting the backup, what is that solution? If deleting the 4 backup is the best option, what are the "risks" of deleting the backup? Like would I lose anything I restored onto my 5s from the 4 backup, etc.?

Hi girdster,
Thanks for using Apple Support Communities. Based on what you stated, it sounds like you need to manage your iCloud storage. I would recommend that you read this article, This tells you how to manage and how to delete a backup.

Limiting Time Machine backup Size with WD MyBookLive and 10.8

I cannot take credit for the any part of this solution; merely for merging and clarifying how the solutions discovered by 2 Apple Support Communities contributors much smarter than I (namely “Pondini” – Florida and “himynameismarek”) - worked perfectly for my situation. All cudo’s to these two!
I have about average or better PC skills, but am an absolute newbie with Apple. This week I got a new iMac. Having a number of home PC’s all sharing files and back up space on a Western Digital MyBookLive (“WD MBL”) 3TB network drive (NAS), naturally I wanted to use it to backup the new Mac rather than rushing out to buy an Apple Time Capsule.
There are hundreds of threads on limiting size of a Time Machine (“TM”) backup, many of which required entries in “Terminal” or were devised on older versions of OSX. I’m running OSX Mountain Lion 10.8, so was concerned they may not work.
The issues I wanted to resolve were:
Time Machine will use up all of the space on my WD MBL if left to it’s own devices.
The WD MBL is compatible with Mac and PC’s… which is good… but unlike a back up in Windows 7 Pro which will allow you to make backups in a mapped “share” you create yourself, Apple TM Backups will not; they end up in a hidden folder on the NAS (much like PC backups done with WD Smartware)
At first I thought maybe I could limit the size of a share created in the MBL, but not possible, at least not that I've seen and I have searched for days.
The solutions:
First make sure you have the latest firmware for the WD MBL as of today it is MyBookLive 02.11.09-053. From what I’ve read Western Digital fixed the compatibility issues with 10.8 Mountain Lion just recently.
Next you need to start TM so that it starts to create a back up. You can stop the back up once you see files being copied. Do this before you walk thru the video tutorial by my Marek below. WD MBL will create the hidden folder you need to find for TM Backups. This folder is called “TimeMachine” but it is not visible even in the “MBL_NAME-backup” folder in Finder.
Open safari and type “ afp://xxx.xxx.x.xxx ” but use your own ip address of your MBL. Mine was 192.168.1.120, yours will be different.
It will ask how you want to connect. CHOOSE AS A GUEST even if your MBL is protected… I’m not sure why it works but it does. Then a window will come up asking which share you’d like to mount. You will see all of your own shares plus one called software and now one called “TimeMachine”. Choose that one.
Now in “Finder” you will see a mounted shared item called “YOUR_MBL_NAME-“ (the same as the one that is probably already there but with a dash(-) at the end). You’ll also see a new “device” in the device list called “Time Machine Backups” (If you already have watched the video tutorial by Marek, you’d know you are looking for a file called “YOUR_MACHINE_NAME.sparsebundle”. Well if you browse the folder “Backups.backupdb” in the Time Machine Backups device you won’t find it… again I don’t know why but you won’t. It resides in the hidden folder called “TimeMachine” that is now visible in the thing you just mounted in step 4)
NOW watch this video tutorial http://youtu.be/Nq7mSizqUSI and follow it step by step.
Voila... issues resolved. Thank you Pondini and Marek!

Try Use Terminal to limit Time Machine sparcebundle size on timecapsule,
should work to limit Time Machine backup size on any NAS or external disk (or not...)
sudo defaults write /Library/Preferences/com.apple.TimeMachine MaxSize 500000
to return to ilimited
sudo defaults delete /Library/Preferences/com.apple.TimeMachine MaxSize
if you want to reclame deleted files space shrink it use
hdiutil resize -size 500g -shrinkonly /Volumes/TimeMachineYOURNAME/YOURNAME.sparsebundle/

HT4847 I am only backing up camera roll and a my media app which are 890 MB and 414 MB, i backup everynight why is it full it says my backup size is 4.7 GB when I only have those 2 things?

I am only backing up camera roll and a my media app which are 890 MB and 414 MB, i backup everynight why is it full it says my backup size is 4.7 GB when I only have those 2 things?

The back up is supposed to be a rolling back up and therefore may still contain data from previous back ups. To free up space you may wish to delete the back up and start again.

How to get Systemstate Backup size using PowerShell command in Windows 2008 R2

Hi,
We using WBSummary command to get completed backup status.
I need to find how much data is backed up using powerShell command .
Is there any way to get the details , i can see the GUI but no in command.
Please advise
Regards Gopi K

Hi,
You mentioned that you can see the system state backup size in the GUI. Does the backup size mean the amount of date transferred?
It seems that there is no such a PowerShell to get Systemstate Backup size. You may need to you need a PowerShell scripts to do this work.

Acrobat Pro 9 file size increases 10x

When I edit a pdf file in Acrobat Pro 9, even the smallest edit like the date, my document size increases by 10 fold. Another user, on the same version, makes the same edit and it does not change much at all. I have uninstalled/reinstalled 3 times, tried Reduce File Size and many other things but nothing seems to work. Has anyone else experienced this same thing and found a resolution?

That is my bad...I must have been in a hurry trying to beat the snow storm and misposted. How can I move or delete and get this in the correct forum?
Thanks

RMAN backup with smallest backup size

Oralce 11g2 on Redhat 5. The diskspace is our tightest resource, and we want to an incremental backup with level0 on Sunday and level 1 every week days and Saturday. I am to use the comamnds to do the job--Sunday
backup incremental level 0 tag 'level_0' database plus archivelog;
--Other days
backup incremental level 1 database plus archivelog delete all input;I do not think this is the best practice nor produce smallest backup files.
What are you comments and opinions. Thanks

Pavan, Thank you for reply. Here are the info requested
what is size of DB ??
~250GB, including UNDO and TEMP. It is a dev database and not very big. But we have total 800GB disk space. After setting some housekeeoing folders, and allow some space for data growth, it leaves 180GB for flash_recovery_area.
what would be max size of archive logs generated per day ??
Variable from less than 1 GB to 12 GB
Are you taking backups to tape or Disk ??
Disk. In the 180GB flash_recovery_area, Current backup size is 152GB. If a backup fails to delete obsolete files, the next backup will fill the flash_recovery_area.

PDF size increase

When I edit an image in PS that I extracted from Acrobat, why does the meg size increase with each edit?

I tried that after posting this question and the size was back at the original size, 19mb. I had extracted an image from an ad, color corrected an area, chose Save in PS, closed the image and watched the pdf in Acrobat refresh itself with the edit. I then chose Save in Acrobat, extracted the image into PS again and did another edit. That's when I saw the mb size increase. I can only do one edit in PS and then I have to save it back into Acrobat. If I try to do several different color corrections in PS and choose Save, a dialogue box opens that asks me what I would like to name this temp pdf that saves into a Temp folder. When I was making an edit, saving in PS and then closing that image to save the pdf as the same name, the mb size increased each time until it was up to 334 mb ! I am using Acrobat 7 Pro and PS CS 5.
Thanks for the reply.

File sizes increase in StarOffice 8

I've got a letter I send out about once a month, just changing dates in the contents for each edition. It has a linked .jpg file as background.
In StarOffice 7 the .sxw file size is 8 Kb.
In StarOffice 8 the size has leapt to 44 Kb, whether I save it in .sxw or .odt format.
Why?

I find that file sizes increase both with text documents and with spreadsheets, sometimes by a great deal. One of the reasons I switched from 5.2 to 7 was the much smaller file sizes, since I keep my weekly back-ups on floppies (and am a stingy sort of fellow generally). But I had to run 7 and 5.2 together, since 7 does not handle Sanskrit/Hindi founts (the SO "help" team just asked a whole lot of questions and then disappeared). So now I have (on Windows) 5.2, 7 and 8. I have still not checked if 8 handles these founts. If it does, I can remove 5.2. For the rest, 8 does not seem to offer any advantage over 7 -- not counting the data base, which I have still to look into. File size, in my view, goes against it.

Index size increased after import

hi i mentioned already the index creation problem when i am trying to create index using script after import of table.So droped the table and created table using script and index also without data,then i started to import at tablelevel with indexes=n then ia m importing data from the production database.
The size of the 2 indexes in production is 750 and 1200 mb each in test db both index size increased around double 1200 and 1700 mb each.I used same script in both db.Why this is increased here i took the export with compress=y full database export.Why the index size increased? when i created the index with initial extent and next extent size respective 800 and 100 mb.Whether is it the reason?
with regards
ramya

i gave initial 1000 and next 100 for the index size around 1.1 gb in production but here in test why this became around 1.7 gb,eventhough the pct increase is 50 it should come around 1.3 maximum.Whether it will give any performance problem
wiht regards
