Incremental backup, can earliest dates be deleted?

We are backing up incrementally to a 500GB external drive that now is completely full. We backup daily using Apple Backup software, not Time Machine. Is it valid to delete the earliest dates from the backup drive creating new space? If not, what do people recommend.
Thank you for any suggestions, Scott

buldog,
You might get more responses if you post in the "MobileMe / Backup" forum.

  • No Incremental Backups - Can Only Force Backup

    I waited until the patch was released before posting this message as I thought my issue may go away. It has not...
    Time machine suddenly stopped working about a week ago. I get no incremental backups at all. I can force a backup with no issues.
    Today I read all the help topics, I re-formated my Lacie Disk, my PC name is fine and so is the name of my Lacie drive. I still get no incremental backups. TM says that in an hour it will backup, it does not, TM then says it will backup in another hour, it does not.
    The only thing I might not have done (newbie) is formatted to GUID? I dont know what that is. In disk utility I selected erase and used the MAC OS Extended (Journald) option, I then created 2 partitions, one for TS and one for storage.
    Its starting to annoy me now. Any help would be appreciated.

    I downoaded Bento demo. Then about 10 mins later TM backed up. I then downloaded an iTune and waited for the next schedule backup. That did not work. Strange

  • 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.

  • Time Machine - lost incremental backup

    The preferences panel for Time machine says it keeps
    * hourly backups for the past 24 hours,
    * daily backups for the past month,
    * weekly backups until your disk is full.
    I notice that the reduction of hourly backups to one backup for a day appears to keep the earliest (incremental) backup for that day and deletes the rest.
    To test this, I created a small file on the desktop on 13th Oct 2008 at 18:30, let time machine back it up at 18:45 and I then moved the file from the desktop to the trash at 19:00.
    I checked that the file existed in the time machine backup for 18:45.
    As I suspected, Time machine has only kept one backup for 13 Oct timed 12:01 am. The file is not in the backup for the 13th or 14th Oct (it is now 15th Oct). The original file is still in my trash.
    If this had been an important file that I had deleted accidentally, I would not be very happy.
    For the record I am using a MacBook running OS 10.5.5 using a 500Gb Seagate FreeAgent drive connected via firewire.
    Shouldn't Time Machine consolidate all the incremental backups for one day into the one backup that it keeps (and eventually consolidate the daily backups into the weekly one that it keeps) so that files are not 'lost' in this way?
    Arthur L.

    Welcome to Discussions.
    [This|http://weblog.infoworld.com/enterprisemac/archives/2007/12/howleopardtim.html] explains it well:
    "As Apple presents the Time Machine filesystem view, you can see your system approximately:
    As it was at the top of each hour today
    As it was each day for the past 30 days, starting yesterday
    As it was each week, starting 31 days ago, going back as far as disk space permits
    A distraught user might only be interested in the amount of data he may have lost:
    If you accidentally deleted a file today, you lose up to an hour's work
    If you deleted it between yesterday and 30 days ago, you lose up to a day's work
    If you deleted it more than 30 days ago, you can lose up to one week's work, or all of it."
    Hopefully the file you've lost took longer than an hour to create than the example you tried.

  • Incremental Backup -- Archive Logs

    When we take incremental backups do we need archive logs?
    Here is the scenario if I delete archive log's and then take a incremental level=1 backup of the database, is my database still recoverable?

    Hi,
    >>If a successful incremental backup was performed AFTER the archive log was deleted, you should be OK. If the archive log was deleted after the incremental backup, you should take another incremental backup.
    if the archivelog was deleted that are generated before starting the backup then u don't need that archivelog after sucessfully completion of backup and if this is generated after the backup then u loss the data.So in that case u should take another backup.
    Thanks

  • Restoring a catalog from backup and incremental backups on external Hard drive

    Hello!
    I recently bought a new computer where I installed again Elements 8 (that's the one I'm currently using). From my old computer, I have an initial complete catalog backup which was saved in a folder (I called this folder "Complete catalog backup") on an external hard drive. I also made then subsequent incremental backups which were saved in different folders called "Incremental backup 1", "incremental backup 2" etc. on the same external hard drive. Apparently in Element, I discovered that incremental backups can't be saved in the same folder as initial complete backup!
    How should I proceed now to restore my catalog on my new computer? I know how to do it when one has only a complete initial catalog backup, but now I have also several incremental backups (contained in folders "incremental backup 1", "incremental backup 2" etc.), I just don't know how to proceed.
    Some help would be very much appreciated.
    Thanks a lot

    First and foremost: Forget re-importing. You would loose all your edits. Importing is strictly only for images that have never been imported before.
    The remedy for "missing" photos is to re-link them.
    In Lr / Grid View right-click the top-most folder in the folders panel. By "top-most" I mean the parent folders of all folders. If you have several parent folder right-click one of them.
    Then select <Find Missing Folder>, navigate to the corresponding folder on your new drive E and select it. Do this for every other parent folder. If the folder names and structure haven't changed Lr will find the sub-folders on its own.

  • Incremental backup confusion

    i a reading the RMAN doc i have one confusion in one paragraph please clear me
    How Incremental Backups Work      
    Each data block in a datafile contains a system change number (SCN), which is the      
    SCN at which the most recent change was made to the block. During an incremental      
    backup, RMAN reads the SCN of each data block in the input file and compares it      
    to the checkpoint SCN of the parent incremental backup.      
    If the SCN in the input data block is greater than or equal to the checkpoint SCN of      
    the parent, then RMAN copies the block.
    my confusion is what is checkpoint SCN of the parent?
    tks & regards
    umaisi

    thanks paul,
    actually i am confused checkpoint scn,both are different thing checkpoint occurs due to log switch while scn as you told from oracle doc...!!
    A stamp that defines a committed version of a database at a point in time. Oracle assigns every committed transaction a unique SCN.
    but where i am reading
    If the SCN in the input data block is greater than or equal to the checkpoint SCN of the parent, then RMAN copies the block.
    it should be like
    If the SCN in the input data block is greater than or equal to the SCN of the parent, then RMAN copies the block.
    but why it is written checkpoint SCN ..may be it is some other concept regarding checkpoint SCN therfore i am confused please clear me..
    what is checkpoint SCN?
    tks & regards

  • How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!

    How to create backup file on itunes for ipod touch 4g game apps data? Is there a way to do it? I want to try an app on my friend's computer, but you can't add apps on another computer without having your own ipod's data being deleted. Thx for any help!
    I want to know how to create a backup file (because I'm pretty new with itunes, and it's hard to use it for me still), how to store my app data/media/videos, etc. And how I can retrieve them back when I'm done with the app I tried on my friend's computer.
    If anyone can help, it'd be great! Thank you so much!

    Sure-glad to help you. You will not lose any data by changing synching to MacBook Pro from imac. You have set up Time Machine, right? that's how you'd do your backup, so I was told, and how I do my backup on my mac.  You should be able to set a password for it. Save it.  Your stuff should be saved there. So if you want to make your MacBook Pro your primary computer,  I suppose,  back up your stuff with Time machine, turn off Time machine on the iMac, turn it on on the new MacBook Pro, select the hard drive in your Time Capsule, enter your password, and do a backup from there. It might work, and it might take a while, but it should go. As for clogging the hard drive, I can't say. Depends how much stuff you have, and the hard drive's capacity.  As for moving syncing from your iMac to your macbook pro, should be the same. Your phone uses iTunes to sync and so that data should be in the cloud. You can move your iTunes Library to your new Macbook pro
    you should be able to sync your phone on your new MacBook Pro. Don't know if you can move the older backups yet-maybe try someone else, anyways,
    This handy article from Apple explains how
    How to move your iTunes library to a new computer - Apple Support''
    don't forget to de-authorize your iMac if you don't want to play purchased stuff there
    and re-authorize your new macBook Pro
    time machine is an application, and should be found in the Applications folder. it is built in to OS X, so there is nothing else to buy. double click on it, get it going, choose the Hard drive in your Time capsule/Airport as your backup Time Machine  and go for it.  You should see a circle with an arrow on the top right hand of your screen (the Desktop), next to the bluetooth icon, and just after the wifi and eject key (looks sorta like a clock face). This will do automatic backups  of your stuff.

  • I'm having some difficulty with Time Machine.  It appears to be deleting backups from random dates on my external hard drive.  I am not deleting them.  Are they hidden and how do I prevent this from happening?  Can I retrieve them?

    I'm having some difficulty with Time Machine.  It appears to be deleting backups from random dates on my external hard drive.  I am not deleting them.  Are they hidden and how do I prevent this from happening?  Can I retrieve them?

    ... I didn't know that Time Machine was more a last resort back up instead of main back up.
    Don't rely upon Time Machine to the exclusion of all else. I compliment Time Machine with a periodic "clone". TM is much better than nothing, but it's a safety net, not a hammock
    Here is my understanding of Time Machine's file deletion algorithm, distilled from Pondini's FAQ, Apple's KB articles, and my own observations.
    Time Machine deletes ("thins") files from the backup disk as follows:
    Hourly backups over 24 hours old, except the first backup of the day
    Daily backups over 30 days old, except the first backup of the week
    Older backups get deleted when Time Machine requires space and you deleted them from the source disk.
    Therefore, assuming TM has been performing at least one backup per day, backup files will remain available:
    at least thirty days, if they existed on your Mac for at least a day
    until you run out of space, if they existed on your Mac for at least a week
    In addition to the above, Time Machine always keeps one complete copy of your source disk so that the entire volume could be restored if necessary. Any files that remain on your source volume will be present on the TM backup, no matter how old they are.
    If you are using 250 GB of space on your source disk, its Time Machine backups are likely to require at least twice that much. A good estimate of the minimum required backup volume size would be about three times the size of your source disk - 1.5 TB in your case.
    A more thorough explanation would require Pondini since he has plumbed Time Machine's mysteries far more than I have.

  • Can I delete incremental backups on my harddisks?

    I use a mac pro with four internal hard drives. Typically one of the hard drives is JUST for backing up files.
    A. I don't really need dated or incrementals
    B. I only use that drive as a backup
    C. Currently, I have one full back up and one months worth of incremental backups already saved to the drive.
    But I'm noticing that (obviously) Backup is eating away at the free space on that drive.
    Questions:
    1. Can I delete older increments?
    2. Can I restore directly from the Full backup and just disregard the increments altogether?

    my apologies. This was posted to the wrong forum.

  • Can't make an incremental backup in PSE 10 Organizer

    I don't understand why I can't make an incremental backup in PSE 10 Organizer. I made my first full backup to my external drive a week ago. Today I tried to make an incremental backup. After selecting Incremental Backup from the file menu, a new screen appears asking for the Backup Path, and so I entered (by selecting) the full path name on my external drive where I made my original backup. But, next, it wants to know the name of the "Previous Backup file." I have absolutely no idea what the program wants at this point. What particular file does it want me to enter as the "previous backup file"?? There are hundreds of files in my backup directory. The backup directly does have a file called "Backup.tly" which I entered, hoping that this is the file it wants, but then I get this error message: "I:\Pictures\Adobe\Backup.tly does not contain a backup set for the current catalog. Please locate the last backup you made for this catalog." What am I missing here?
    Many thanks for your help,
    Jeff

    Hi Jeff
      Once you have a full back up you can make incremental back ups but you need to follow a set routine. It’s not very intuitive.
    Start by creating a new folder or label a new CD/DVD Disk - it’s best to use dates e.g. “PSE10 incr backup 2012-0104”
    Press Ctrl+B and check Incremental, then click Next
    Highlight your drive containing the last backup and click the bottom Browse button (previous back up file) then navigate to the TLY file and click open.
    Click the Browse button above and navigate to your new folder “PSE10 incr backup 2012-0104”
    Click Done.
    If your full backup originally contained 500 images, the incremental backup will only contain changes since the last backup e.g. files B000501.jpg, B000502.jpg etc
    If you ever have to do a complete restore you start with the TLY file from the latest incremental backup. The program automatically recognizes the number of incremental steps and you will be prompted to insert a disc or navigate to the appropriate drive.
    Incremental backup’s are obviously much quicker to write to disk but I recommend that you periodically perform another full backup and delete any earlier backups.

  • Can I recover a deleted device backup in windows iTunes?

    I was backing up my iPhone with iTunes and a couple of things happen: 1. All my phone numbers where deleted after the backup.
    2. Me thinking this was a glitch, I attempt restoring from backups all my data. Instead of fuged-up further. I said to myself, maybe the backups will reset if close iTunes; maybe they will reset if I delete older ones (in the past when I did this they remained in the backup history). Nothing happen and I lost my data, and my backups.
    So, can I recover deleted device backups in PC? Please Help. Thank You.

    Open up old files in the autosave vault until you find one with the deleted bin.  copy it into the current project.

  • Can I use an incremental backup disk for a restore function?

    I have loaded PSE7 on my new PC. I have a full backup set and also an incremental set created after the full backup. After doing a File/Restore with the full backup set, can I use the incremental set to add the remaining picutures or do I need to do a new full backup first and only use it? If I can use the incremental set, are the steps to load it the same as for the full backup?

    I have given up incremental backups because they don't save any time. I have found that the messages in the restore process are misleading. I don't know for sure why, but to restore, I got the best results by restoring the last incremental backup first, then the older ones and the original. If your incremental backups are correct, each in a separate folder or disk, you have a full version of your catalog at the time of backup stored within the folder or disk. I suppose this is to start with the latest catalog version and completing the process by comparing with previous versions, which ensures not adding deleted items.
    I'd be interested to get other views on that matter !
