Backup strategy for FULL recovery model

Hi,
 We currently have a DB that is in a FULL recovery model and is Synchronized (mirrored) to a DR site. For extra safety, we are told to take regular backups of this db. Now is it possible to take a weekly FULL backup and then differential throughout
the week. OR have two FULL backups (Sunday and Wednesday) and then differential on other days. 
Does the recovery model affect how a backup can be taken. Will this affect the log file (it is currently set to restricted growth by 400mb)
System: SQL Server - 2008 R2
Thanks.

Thanks Ashwin and Prashant. Based on your responses and the acceptable RTO i have the below backup plan. 
Sunday and Wednesday FULL backup
Everyday - Differential
The transaction log done every hour.  
For example: 
Sunday 11:50pm - FULL backup done
Differential done daily at 1:00 am
So if the DB crashed or corrupted on Wednesday @ 6:am , I would have to restore with the below ?
-- Use the Sunday FULL backup
-- Use the differential from Wednesday @ 1:00 am 
-- Use the transaction logs from 1:00 am to 6 am.
Would that work?

  • Simplest Backup Strategy for Full IMAP server

    Hi,
    I have just reorganized all of my mail for the last few years on to my university Exchange server (IMAP) and of course it is full. I want to preserve my old messages and reduce my emails to the most recent ones on the Exchange server. What is the simplest approach to saving the old emails? Do I copy them to my "on the mac" and then copy them to CD, or is there a simpler solution?
    Grant

    Hi Grant.
    Mail stores most preferences and all the account settings in ~/Library/Preferences/com.apple.mail.plist (except the passwords, which are stored in the keychain). Everything else, including all your messages and mailboxes, is stored in ~/Library/Mail/.
    Similarly, Address Book (whose data you should back up as well) stores the settings in ~/Library/Preferences/com.apple.AddressBook.plist and the data in ~/Library/Application Support/AddressBook/.
    These files can be backed up just like any other data files. The affected applications shouldn’t be running while making the backup.
    Actually, while you’re at it, you might as well back up your entire home folder...
    For IMAP accounts, if Mail > Preferences > Accounts > Advanced > Keep copies of messages for offline viewing is set to All messages and their attachments, Mail keeps a local copy of those messages on your hard disk that becomes part of any backup that includes the ~/Library/Mail folder.
    Selected messages can be exported in standard mbox format by doing File > Save As in Mail and choosing Raw Message Source from the Format popup menu. Standard mbox files can be imported into most mail clients. In particular, they can be imported back into Mail doing File > Import Mailboxes and choosing Other as the data format. Using this format, however, would cause some status flags to be lost (e.g. whether a message has been replied to).
    Locally stored mailboxes can be copied to the Desktop or anywhere else by just dragging them there from Mail itself (for server-stored IMAP mailboxes, copy the messages to locally stored “On My Mac” mailboxes in Mail first). These, however, are *.mbox folders (not standard mbox files), where messages are stored in individual *.emlx files that other mail clients don’t know or care about. They can be imported back into Mail doing File > Import Mailboxes and choosing Mail for Mac OS X as the data format.
    Andreas Amann’s Mail Scripts has an Archive Messages script that you may also find useful.
    Finally, there are several backup/archiving solutions for Mail available out there:
    http://www.hawkwings.net/plugins.htm#archive
    Note: For those not familiarized with the ~/ notation, it refers to the user’s home folder. That is, ~/Library is the Library folder within the user’s home folder, i.e. /Users/username/Library.

  • DPM is Only Allowing Express Full Backups For a Database Set to Full Recovery Model

    I have just transitioned my SQL backups from a server running SCDPM 2012 SP1 to a different server running 2012 R2.  All backups are working as expected except for one.  The database in question is supposed to be backuped up iwht a daily express
    full and hourly incremental schedule.  Although the database is set to full recovery model, the new DPM server says that recovery points will be created for that database based on the express full backup schedule.  I checked the logs on the old DPM
    server and the transaction log backups were working just fine up until I stopped protection the data source.  The SQL server is 2008 R2 SP2.  Other databases on the same server that are set to full recovery model are working just fine.  If we
    switch the recovery model of a database that isn't protected by DPM and then start the wizard to add it to the protection group it properly sees the difference when we flip the recovery model back and forth.  We also tried switching the recovery model
    on the failing database from full to simple and then back again, but to no avail.  Both the SQL server and the DPM server have been rebooted.  We have successfully set up transaction log backups in a SQL maintenance plan as a test, so we know the
    database is really using the full recovery model.
    Is there anything that someone knows about that can trigger a false positive for recovery model to backup type mismatches?

    I was having this same problem and appear to have found a solution.  I wanted hourly recovery points for all my SQL databases.  I was getting hourly for some but not for others.  The others were only getting a recovery point for the Full Express
    backup.  I noted that some of the databases were in simple recovery mode so I changed them to full recovery mode but that did not solve my problem.  I was still not getting the hourly recovery points.
    I found an article that seemed to indicate that SCDPM did not recognize any change in the recovery model once protection had started.  My database was in simple recovery mode when I added it (auto) to protection so even though I changed it to full recovery
    mode SCDPM continued to treat it as simple. 
    I tested this by 1) verify my db is set to full recovery, 2) back it up and restore it with a new name, 3) allow SCDPM to automatically add it to protection over night, 4) verify the next day I am getting hourly recovery points on the copy of the db. 
    It worked.  The original db was still only getting express full recovery points and the copy was getting hourly.  I suppose that if I don't want to restore a production db with an alternate name I will have to remove the db from protection, verify
    that it is set to full, and then add it back to protection.   I have not tested this yet.
    This is the article I read:

  • Backup strategy for ebs R12?

    Hi,
    I have a couple of questions regarding to backup strategy for ebs R12.
    Let's say that we have one application server and one database server running, and we would like to have a backup periodically for both servers.
    This means that we want to have the exactly same backup of configurations and other files for the application server and the database server in case of any fatal crashes in the servers.
    I went through some discussion threads and it seems common way is to use RMAN for the data of database and file system copy for application and database servers. But, I would like to know what's the best way or recommended way for the backup strategy for data and server files of Oracle e-business suite.
    Do you guys have any suggestion for this?
    Thanks in advance.
    Cheers,
    SH

    Hi SH;
    I suggest check first our previous discussion
    backup and recovery startegy for EBS
    Re: Backup System
    Backup Policy for EBS can
    If you make search you can find many other thread which is mention same question
    For your issue basicly what we do
    1. For our prod db, if possible we take weekly cold backup(sunday) and take rman backup also daily(full backup, but it depends system you can prefer to take incremental)
    2. For our system we take file system backup weekly(OS base)
    3. For application we take backup every sunday(for some system 15 days or 30 days period). The most important point here if your system prod, and if you need to apply patch to your system you need to have valid backup and also need backup for after patching
    One other important issue is we run preclone sh before take backup for apps and db tier
    Regard

  • Long-term  retention backup strategy for Oracle 10g

    Hello,
    I need design a Archivelog, Level 0 and Level 1 long-term retention backup strategy for Oracle 10g, It must be based in Rman with tapes.
    ¿Somebody could tell me what it's the best option to configure long-term retention backups in Oracle?, "CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 1825 DAYS;" It's posibble ?
    Regards and thanks in advance

    Hello;
    RECOVERY WINDOW is an integer so yes its possible. Does it make sense?
    Later My bad, this is Oracle 11 only ( the gavinsoorma link ) . Getting harder and harder to think about 10. Don't think I would use RECOVERY WINDOW.
    I would let the tape backup system handle the retention of your rman backups.
    Using crosscheck and delete expired commands you can keep the catalog current with the available backups on tape.
    Oracle 10

    http://web.njit.edu/info/oracle/DOC/backup.102/b14191/advmaint005.htm
    Oracle 11
    If you want to keep 5 years worth of backups I might just use KEEP specific date using the UNTIL TIME clause :
    keep until time 'sysdate+1825'More info :
    RMAN KEEP FOREVER, KEEP UNTIL TIME and FORCE commands

  • Changing from full recovery model to simple in sql 2012 always on

    how do I change from a full recovery model to simple in an always on sql 2012 setup? When I try to change it it gave this error

    The physical size of the log file will not change unless you manually shrink the file.  A backup marks the log space as "reusable" internally.

  • What are Full Recovery models configured to content databases

    hi
    now in my SharePoint farm SharePoint Content Database are not  configured to run with Full Recovery model
    what are these full recovery models and is needed 
    adil

    With a full recovery mode you can (in case of appropriate backuping) to restore database to almost any specific time. Like "Monday, 2:34PM".
    So if your SharePoint site is using to exchange documents and heavily updating - I recommend you to switch Full mode on and backup full database at least once per week, backup logs every hour or as your information policy requires.
    If this is mostly readonly site (like publishing portal) it is not a problem to run it in Simple mode, IMHO.

  • What is the backup strategy for your rpool?

    Hi all,
    May I know what is your backup strategy for rpool? like how to integrate with the netbackup or any other backup software
    Is it using zfs send a data stream to a file and backup that file using backup software??
    Aside the above method, can we also use the UFS method?
         backup software to backup entire / /var..........  etc....
         1. re install the OS
         2. install the backup client
         3. create a zpool (rpool-restore)  using a 2nd disk,
         4. mount the new zpool  (rpool-restore) to /restore
         5. restore all the file in  /restore
         6. install boot blk,
         7. boot from 2nd disk
    Any more idea?

    HI Willy,
    According to the Flash Archives limitation stated in Oracle website, if the OS is with a child zone, it will not work right?
    http://docs.oracle.com/cd/E19253-01/821-0436/6nlg6fi8u/index.html
    I am thinking that using the traditional way to do it.
    Use a backup software, for example, networker, TSM, netbackup.. to back up the following:
    /rpool
    /export/
    /export/home
         1. re install the OS
         2. install the backup client
         3. create a zpool (rpool-restore)  using a 2nd disk,
         4. mount the new zpool  (rpool-restore) to /restore
         5. restore all the file in  /restore
         6. install boot blk,
         7. boot from 2nd disk
    will it still works?

  • Good backup strategy for a mailserver?

    Hi,
    What would be a good backup strategy for a mailserver and what software would you use. I've got Retrospect right now ...
    Thanks a lot.
    Jerome

    Yeah, ptero, I know. I'm using mailbfr and it seems to work quite fine.
    I didn't express myself clearly in this thread, I was in fact looking for the best way to backup a whole MacOS X Server whose primary function is being a mailserver.
    I'm backing up the mailbfr via Retrospect on another server, and I'm using Carbon Copy Cloner from time to time to make an image of the whole server. But is that a good idea? I've got a neat program on my Windows servers which makes 'continuous' incremental images of the whole disk while the servers are being used. Is there anything like that for Mac? Or how do you back up the system configuration of your Mac servers?
    But perhaps this is the wrong subforum to ask questions like this?
    Thanks alot anyway!

  • Time Capsule backup strategy for multiple drives and OS

    I'd like a backup strategy based on Time Capsule but have a few twists from a straightforward situation and would appreciate any guidance with setting it up. My hardware situation is:
    - Two MacBooks, on 10.5, one with an 80 gb drive, the other with a 120 gb drive.
    - One G4 iMac, on 10.4, with a 60 gb drive
    - One LaCie NAS drive, used primarily as the storage space for music and video, and currently not backed up anywhere (making me nervous!)
    Ideally I'd like each of these four units to be backed up on Time Capsule; and my configuration questions are in two areas:
    1) Backup software: I'll use Time Machine to backup the MacBooks, but not sure about the G4 and NAS drive. These could be backed up on a more ad hoc basis (I don't need hourly updates). Is this best handled with a third party app like SuperDuper to allow for incremental backups?
    2) Partition/disk image: is it wise (or indeed necessary) to create partitions for each of the above sources (I gather from reading other posts is seems the best way to achieve a partition is to create a disk image). I'm not sure if there would be any unintended consequences by doing so (or not),and if so if a sparse image disk image is better than a sparse bundle disk image given the above, so any guidance to help make sure it's set up as flexibly as possible from the outset would be greatly appreciated.
    Thanks in advance for any advice.

    G'day Michael,
    Sounds like it is time to buy OS X Server!!!!
    I think you are on the right track. As a "left field" suggestion, why not get two big drives, and use one of them as a file server. Get everyone to use the file server for any critical documents that they want backed up centrally/continuously. Then back the file server system up onto the other big drive using TM.
    This reduces administration somewhat, and privacy can be retained with careful username management across the network.
    Assuming that the three MacBooks are similarly configured from a system perspective, there is not a lot of point in having full bootable clone's of each one. Perhaps create a bootable clone from one of them each week - and clone the other two into disk images (which are not bootable, but are restorable) as frequently as needed.
    Cheers,
    Rodney

  • Backup strategy for my new computer

    I have a PPC mac mini that my kids use and I use a powerbook. I'm about to buy a macbookpro for me and update the kids to leopard. They also need more storage so I will give them an external firewire drive. I haven't used leopard yet and I'm trying to plan my backup strategy. I want to have regular backups so time machine looks great but do I really need to have a bootable copy of my system? Can I just backup my data and then access my files via the kids machine if necessary? A separate drive would give me more flexibility but is the quality going to be as good as the server quality drive in time capsule?
    Also, should I buy an external drive (which one?) that I can connect to an airport extreme if i want in the future - or a time capsule from the word go? We run two airport networks in the house so could I back up via wifi and then access my files via wifi using the kids computer?
    Sorry to ask all these questions but its hard to know the best policy before I've started using leopard - and if I don't do it straight away it will inevitably be too late by the time I do!

    Rachel Taylor wrote:

    Well, if you ever get stuck and can't boot from your internal drive, you will. Drives are just mechanical devices and are prone to failure. You can use SuperDuper for free cloning.

    It depends what you want. Actually, wireless is the slowest speed on transfer -slower than USB.

    It's very wise to ask about backup. I can't believe how many folks use their Macs for their livelihood and have no backup at all.

  • Advice needed for backup strategy for office

    My office is switching from PC to Mac (yay!) and I'm in charge of setting up the system. We'll be using 4 iMacs and a Mac Mini Server with ethernet connections. I'd like to ask what is recommended for backing up these computers.
    My thought would be to back up the iMacs separately from the server - is this definitely the way to go?
    I'm thinking to get a 3TB Time Capsule for the 4 iMacs so that Time Capsule will do automatic backups.
    - Is it OK to have 4 iMacs backup to one Time Capsule like this?
    As for the Mac Mini server, I'm not sure how to best back it up.
    Since it has two 1TB drives, I'm thinking of using one drive for data and having it automatically backup to the other internal drive. Any thoughts on this idea?
    Or, it is possible to connect an external USB drive to the Time Capsule's USB port, and have Time Machine backup the server to the external drive?
    Any advice is greatly appreciated!

    The TC is really a home solution.
    For business I think you should consider something extra.
    Although 4 computers and a server is not a big setup, it is worthwhile doing a more professional backup and use something more professional than Time Machine.
    For instance..
    http://www.retrospect.com/au/products/mac
    I have not used it.. but I see it recommended in business / larger installs. It is not cheap but well worth considering.
    I would not use the internal disk of the server for backup.
    As for the Mac Mini server, I'm not sure how to best back it up.
    Since it has two 1TB drives, I'm thinking of using one drive for data and having it automatically backup to the other internal drive. Any thoughts on this idea?
    You can raid the two disks if you don't need the capacity.
    But backup to a USB drive plugged in.. USB3 drives are cheap and speedy. Much more reliable than using network drives.
    Raid for integrity of working data.. backup to separate change over disks.
    So weekly you change over the USB drive for backup and store the other one at home.
    I'm thinking to get a 3TB Time Capsule for the 4 iMacs so that Time Capsule will do automatic backups.
    - Is it OK to have 4 iMacs backup to one Time Capsule like this?
    You can do this.. It is fine to have 4 Macs backup to it. But if you are not using the wireless router it is a waste.. you can just backup over network to the server.. TM works fine on network.
    You can buy another 3TB USB drive for backup of the clients.. normally though you want all the working data on the server and back that up. You are thinking a more peer to peer model.. once you introduce the server you can work on a more server client model where the current files are held on the server.

  • New to sap - need help in configure backup strategy for SAP XI server.

    hi gurus
    being a netweaver guy, recently i have been given  the responsibility of few basis activities.like database backup.
    can any one tell me clear procedure to take both daily online and weekend full offline backup of oracle in to disk first and then to tape.   i have seen in the internet  material few discussing about brbackup and few about sap DB13. i am totally confused which one to use, and which is good. please help
    akhil

    Hi,
    welcome on board as SAP Netweaver guy,
    don't be confused both DB13 and BRtools are the same both of them will call brbackup.
    to configure the brtools you have to change in your brtools profiles located at  %ORACLE_HOME%/dbs
    please before changing any thing take backup from that folder.
    - to take the backup to disk then to tape you will need extra backup software, because using the SAP slandered tools you have to select either Disk or Tape.
    Thanks

  • Backup strategy for Oracle E-Business Suite

    Hi guys,
    I am administrating an EBS (E-Business Suite 11i) System with two Application servers and two database servers running in RAC mode. At the moment, the system has just been backed up at database tier by using rman. Now, I also want to backup application tier. So, here is my questions:
    - What is the most important thing which I must care when I backup the application. Because I am new at EBS so, more details and specific is, better is.
    - Is a good approach if I back up entire the current system data (include binary file, class file, misc files, forms, reports,...)
    Finally, anyone can share some experiences when do backup these systems?
