Level 1 incremental backup taking larger space

Hi All,
Yesterday i had level 1 incremental backup. Backup completed successfully but its size was as equal as Full Backup.
What could me the possible reason for that ?
Environmnt is Oracle 10g R2 2 Node RAC on windows.

  • Level 0 incremental backup

    Hi,
    is the level 0 incremental backup a full backup ?
    Thank you.

    Stellios wrote:
    A level 0 backup is not the same as a full backup in that you cannot perform an incremental backup over a full but only over an incremental level 0. So for a large database this may affect your backup strategy (backup running overtime because of no level 0 to start with and implicitly creating one).
    "A level 0 backup must exist as the base backup for an incremental strategy. An incremental backup at level 0 is identical in content to a full backup, but unlike a full backup the level 0 backup is considered a part of the incremental strategy. If no level 0 backup exists when you run a level 1 backup, then RMAN makes a level 0 backup automatically."
    See INCREMENTAL LEVEL:
    http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta009.htm#i1009966
    Correct.
    Level 0 backup is not same as full backup because it's not possible to take level 1 backup after nonincremental full backup
    Level 0 backup is identical in content to full backup because they both take backup of ONLY used data blocks
    To show it, backup database as "full backup" and as "level 0 incremental backup" and check sizes:

  • Why are the incremental backups so large??!!   16GB vs. 300MB

    I have the Time Machine system preference turned to Off, as I do the backups Manually every couple of weeks (Back Up Now from the Menu Bar). Here is what puzzles me: I don't work with large files. My incremental increase in size in a couple of weeks might be 200-300 Megabytes. Yet, each incremental backup is 12- 16 GB, which of course takes forever. Can anyone shed any light into why the large size??

    what Tesserax said ! or, if you have +disk warrior+ installed, it could be its +trash protection+ folder.
    install timetracker from here. it will let you look at any given backup and determine what has been backed up. that way, i discovered the DW folder as the culprit and excluded the sucker from being backed up. voila, backups came back to a regular size

  • Incremental backups taking waaaaaaaaay too long!

    Recently, my TC backups using Time Machine have been taking much longer than normal. Even when nothing on my Mac has changed since the previous hour's backup, it normally takes 45 minutes or more, when it used to take just a few minutes. Nothing in my setup has changed in months, and I'm stumped as to what the deal is.

    You can be fooled.
    Here is a valuable App - [Time Tracker|www.charlessoft.com/TimeTracker.zip].
    It will tell you for each backup exactly what was backed up and how much space was required. It will enable you to determine if there is something being backed up that was large which you didin't realize or whether you have another problem.

  • Why is my Time Machine Backup Taking More Space then my Hard Drive?

    I have a Late-2009 MacBook model with a 250GB hard drive.  My external drive is 1TB.  I use it for Time Machine backups as well as other storage.  My backups on that drive are a bit less then 900GB, which is 90% of that disk.  My hard drive is only 250GB so how is it over 3 times as large?  I would like to have more storage for other files.  What would you recomend doing?  Can I partition the external disk?

    How time machine works is that it makes an initial back up and from there it scans your system for changes.  When it finds a change it adds the changes on top of your current backup. So if you have a folder full of pictures then rename them or change them, etc it'll resave/archive the pictures ontop of what it already backed up.  It doesn't keep a single "state" of backup.  This allows you to "look back in time" and see if you can find something you might have accidentally changed or deleted or etc.  Once the disk becomes full it will delete the oldest backups to keep archiving newer files.
    I would suggest that you partition your external drive to a size that allows you to keep free the desired extra storage space you're looking to use.  For example partition the drive to two 500GB partitions one for storage one for time machine.

  • Applying level  1 Incremental Backup (Abid)

    Dear All
    I have taken Prouduction database backup incremental level 0 from machine A
    and restored in on Machine B ( another machine). Now i have taken incremental level 1 backup of Production with the following command,
    BACKUP INCREMENTAL LEVEL 1 DATABASE;
    Now i want to apply it on Machine B. Kindly tell me steps and command.
    Thanks

    What is the Machine B database doing? Is it a standby?

  • Why are my backups taking up space on my HD and not my time capsule?

    I've been experiencing sluggish performance on my late 2012 Macbook pro. I have a time capsule (most recent model) and use that for backup. When I went to system information about my storage, it says that there is right around 200 GB of backups on my hard drive itself, why is this?

    Most likely due to Time Machine snapshots made for each hour your computer is not connected to the backup drive. To prevent these in the future be sure to turn off Time Machine when you aren't connected to your backup drive.
    These snapshots take up shadow space meaning if the system needs space and there isn't enough, then it will remove the number of snapshots needed to make space. So the space is not in technical use on the drive. But if you want all the space returned and turn off snapshots, then see:
    Time Machine Snapshots
    Open the Terminal in the Utilities folder and enter or paste the appropriate command line. Press RETURN and enter your admin password when prompted. It will not be echoed. Press RETURN again.
    To turn them ON: sudo tmutil enablelocal
    To turn them OFF: sudo tmutil disablelocal
    Note that turning them OFF will also delete all existing snapshots.
    For more about snapshots see: OS X Mountain Lion- About local snapshots.

  • Is a Level 0 Incremental the same as Backup Database?

    hi experts,
    This is a 10g database running in archivelog mode.
    This is the backup scheme I'm currently using:
    backup database plus archivelog; (runs once per day)
    backup incremental level 1 database; this runs every 3 hours
    (All the incrementals I make are level 1.)
    In another forum, I was advised to make a level 0 incremental backup, because you cannot restore a level 1 if there was no level 0 made earlier. Now, I'm looking for the RMAN expert's advice :-)
    ** If I do this will I have what I need to be able to restore: **
    - backup incremental level 0 database; (this will run once per day)
    - backup incremental level 1 database; (this will run every 3 hours
    In other words, will I miss anything if I dont do a backup database ?
    Thanks, John

    If you taking level 1 backup and If you dont have any level 0 then RMAN take hole database backup (level 0) with level 1 command.
    It is always advisible to take level 0 and follow the level 1.
    I advise to see the below doc which covers all your doubts and best way to backup.
    Hope this solves your issue.

  • Incremental Backup Levels

    Hello Everybody.
    I want to know the description of all 0-4 levels of incremental backups. Anybody please tell me in details.
    Thanks and Regards

    ora-boy
    Questions like this have version specific answers. Almost all questions have.
    It is useless and silly to post any question without any version information.
    Here's why
    In 8i and 9i: incremental levels are between 0 and 3. There is nothing to explain,
    1>0, 2>1, 3>2. That's all.
    In 10g there is only 0 and 1. The higher levels have been removed.
    Please stop asking questions without version information, assuming people keep track of your version (which we don't) or will summarize it for all available versions (which we won't )

  • Can we take Incremental backups without Level 0 backups

    Kindly share the procedure if any by which we can initiate an incremental backup without Level 0 backup

    Kindly share the procedure if any by which we can initiate an incremental backup without Level 0 backup
    There is NO such procedure.
    You can't 'increment' something that doesn't exist can you?
    Please increment the previous number by 1. Can you do that? Of course not because there IS no previous number.
    BY DEFINITION (see the doc) an incremental backup for any level but 0 REQUIRES a previous backup:
    an incremental backup copies only those data blocks that have changed since a previous backup
    A level 1 incremental backup can be either of the following types:
      A differential incremental backup, which backs up all blocks changed after the most recent incremental backup at level 1 or 0
      A cumulative incremental backup, which backs up all blocks changed after the most recent incremental backup at level 0
    Incremental backups are differential by default.

  • Configuring Incremental Backup

    Hi there
    I am designing RMAN backup
    - I want to use Repository Catalog
    - I want to take level zero backup every saturday night
    - I want to take level 1 incremental backup everyday night, except sunday
    - and I want jobs to be scheduled and I prefer not to use EM.
    - I want to check for logical and physical corruptions before taking the backup
    Q1. what is the place of archive log in incremental backup
    Q2. should I include the archive log in level 0, in level 1 or in both
    Q3. so can any one provide me with a sort of template scripts to help me start with
    I know there are wide resources but I wanted a seed to build up on.
    I appreciate any help
    Thanks

    Firstly - you cannot backup archive logs at level 0 or 1. When you think about it archive logs don't change once they are created so why would you ever back them up with incremental level 1 besides there is no option to do this.
    You can say however "backup incremental level 0 database include current controlfile spfile plus archivelog;" in one statement.
    "You can delete the archive logs once incremental backup is complete. It is done automatically by using delete obsolete command."
    Depends if that's what you want to achieve - I personally prefer to backup archive logs at least 3 times before deleting them (BACKED UP 3 TIMES) and also on seperate tapes. The balance is between available disk space for archive logs and requirements of the client. You would hate to compromise recoverability because of a few lost archive logs all backed up on one corrupted or lost tape.
    You should also "sql 'alter system archive log current';" before the backup command to capture maximum data changes.

  • Quesion about the Basic concept of RMAN incremental backup

    I have a problem in understanding the basic concept of two types RMAN Incremental backup ie. Differential and Cumulative. I just don't understand how cumulative incremental backup consumes more space than Differential backup.
    Have a look at the scenario in which Differential backup is used.
    1. On Sunday midnight, a LEVEL0 backup is taken.
    2. On Monday midnight all the blocks that was changed since Sunday midnight are stored in the backup media (tape or disk)
    3. On Tuesday midnight all the blocks that was changed since monday midnight are stored in the backup media.
    4. On Wednesday midnight, all the blocks that was changed since tuesday midnight are stored in the backup media.
    At this point, in the backup media, you have all the changed blocks from sunday midnight to wednesday midnight eventhough it was stored in a daily basis. If you had taken a cumulative backup at wednesday midnight the backup media would have contained the same changed blocks from sunday midnight(LEVEL0) to wednesday midnight, but all at one go instead of daily basis. I don't understand how cumulative backup consumes more space when the backup media contains the same amount of changed blocks as it were in the case of the Differential backup.

    Considering the Scenario you given:
    Sunday : Level 0 backup.
    Monday : You have taken an incremental backup then there will not be any difference in size of backup set for differential or cumulative as the changes from last Level0 backup are considered.
    Tuesday : A cumulative backup (n-1) will have changed blocks since Sunday's Level0 backup but a differential backup(n) will only have changed blocks since Monday. So definitely there will be more space consumed by cumulative backups compared to differentials.
    Hope it helps ...

  • RMAN - Incremental backup / NOARCHIVELOG / Restore & Recover Until Cancel

    I'm testing out a weekly plan as follows:
    Sun : Shutdown db, RMAN level 0 Incremental Backup
    Mon-Sat: Shutdown db, RMAN level 1 Incremental Backup.
    The database is NOARCHIVELOG mode and is 10.2 XE.
    I then run a restore (which I understand to be to move the datafiles from the backup set to their online location). My next aim is to do a recover.
    I'm really confused at this point. Say I take the backup the night before (either a level 0 or 1, I'm assuming that this makes no difference) then in the morning I drop a table accidentally. Okay - I want to go back to the position after the backup. When I do recover, I understand that Oracle applies redo logs written since the backup.
    So I don't want a recover, I want a recover until cancel. When I issue this command it is suggesting that I use an archive log file. Well obviously I don't have any of those so I press cancel thinking that this will bring me back to the point EXACTLY AFTER THE NIGHTLY BACKUP and with my table back. But it doesn't!
    I would be really grateful if anyone has a definitive answer to this - what are the steps to recover a database to the point after the backup was taken ignoring any changes since the backup.
    Thanks all.
    Tom.

    Hi Werner
    Do you mean if the online logs are available with the changes after the last backup until the database restore then there is a possibility to apply changes? Ie at this point I could put in the redo log names instead of the archive log names.
    If they have been overwritten since the backup (ie cycled round completely) then is the behaviour to restore the database and then not apply any logs?
    Do you know if this is documented anywhere? There seems to be an emphasis on ARCHIVELOG mode only, especially in the books I have seen.
    Thanks,
    Tom
