• Backup and restore in Windows 7 will not make an incremental backup

  Hello.

  I have about 400 GB of backup files, for most audio (I have a home studio). Backup and restoration continues to do a new backup full instead of an incremental backup. I tried to disable "Windows Media Sharing whatever" and has no effect. I found the registry entry that the so-called forces a backup under certain circumstances, if I understand correctly. I put the value '0' and he still makes no difference - copy Windows files that I know have not changed over the YEARS and to create a new full backup. My current full backup is December 2014 on a 1 TB external hard drive. It is the backup that I added to-probably on a maximum of 20 additional concerts.

  This is important because in 400 concerts, I have neither the time nor the space to do a full backup every time. I searched these forums and around the web and found nothing more disable sharing of Windows Media Services. For now I'm reduced to manually copy the new audio files on a backup drive, which is heavy at least when dealing with the whims of my Audio sequencer for recording methods and organization of files.

  Please let me know how I can make an incremental backup instead of a full backup of my hard drive. Thanks for your help.

  IMHO, I wouldn't play with the built-in backup.  It is, at best, kludgy, depends on the OS partition, is inflexible and not easy to use.

  IMHO, I would not trust my data or spend my time on it.

• Differential incremental backup for RAC

  I inherited a CAR of two nodes (11r2 on RHEL 5.8 tikanga) with a shared network directory to be used as a backup location. He is the current backup strategy.

  RMAN> show all;
  using target database control file instead of recovery catalog
  RMAN configuration parameters for database with db_unique_name TESTdb are:
  CONFIGURE RETENTION POLICY TO REDUNDANCY 1;  # default
  CONFIGURE BACKUP OPTIMIZATION OFF;  # default
  CONFIGURE DEFAULT DEVICE TYPE TO DISK;  # default
  CONFIGURE CONTROLFILE AUTOBACKUP OFF;  # default
  CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F';  # default
  CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET;  # default
  CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;  # default
  CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;  # default
  CONFIGURE MAXSETSIZE TO UNLIMITED;  # default
  CONFIGURE ENCRYPTION FOR DATABASE OFF;  # default
  CONFIGURE ENCRYPTION ALGORITHM 'AES128';  # default
  CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE;  # default

  CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/snapcf_testdb1.f';  # default
  
  

  The above is for the node 1, node 2 is identical except for line 17 (he refers to the "_testdb2.f").

  The backup script is below.

  run
  {
  recovery copy of database with tag 'ORA_OEM_LVL0_TESTdb_PRIM' until time 'SYSDATE-7';
  backup check logical incremental level 1 cumulative copies=1 for recover of copy with tag 'ORA_OEM_LVL0_TESTdb_PRIM' database;
  backup check logical archivelog all tag 'ORA_OEM_ARCH_TESTdb_PRIM';
  }
  allocate channel for maintenance device disk type;
  crosscheck backupset;
  crosscheck archivelog all;
  delete noprompt obsolete device type disk;
  
  

  I'm a relatively new DBA, but I think that the strategy above maybe even does not work like the "db_recovery_file_dest" SQLPLUS references + FRA (not the shared network directory) and the two places (both FRA directories) and shared network directory without large amounts of data in them.  I think that the previous owners of this CAR may not had adequate support DBA.

  In any case, I thought to change the configuration as such:

  RMAN> show all;
  using target database control file instead of recovery catalog
  RMAN configuration parameters for database with db_unique_name TESTdb are:
  CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

  CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/snapcf_testdb1.f';  # default
  
  

  RUN
  {
  RECOVER COPY OF DATABASE WITH TAG 'incr_update' UNTIL TIME 'SYSDATE - 7';
  BACKUP INCREMENTAL LEVEL 1  FOR RECOVER OF COPY WITH TAG 'incr_update' DATABASE PLUS ARCHIVELOG;
  DELETE ARCHIVELOG ALL;
  }
  
  

  I don't know that miss me a few things in my backup strategy. Any advice is greatly appreciated!

  Thank you

  PS - Yes, we have a license for compression

  Good point about ARCHIVELOG ALL DELETE. Your suggestion would be to replace it with DELETE NOPROMPT OBSOLETE? Do I need to perform a cross-checking beforehand or Oracle already know from the backup?

  1. CONFIGURE ARCHIVELOG DELETION POLICY TO SAVED 1 TIME TO THE DISK.
  2. INCREMENTAL BACKUP LEVEL 1 for BACK OF COPY WITH TAG "incr_update" DATABASE MORE ARCHIVELOG;
  3. DELETE ARCHIVELOG ALL;

  As you have Setup CONFIGURE the STRATEGY of DELETING ARCHIVELOG RMAN will not delete archivelog until archivelog backup 1 time on the disc.

  But HemantKChitale have a good point, if for some reason any person clearly that the configuration you'll probably ARCHIVELOG DELETE without backup, do your backup is inconsistent.

  So is advised 'INCREMENTAL BACKUP of LEVEL 1 TO RETRIEVE COPY WITH TAG "incr_update" base of DATA PLUS ARCHIVELOG DELETE INPUT' or 'BACKUP ARCHIVELOG ALL DELETE INPUT';

  You can avoid delete the archivelogs without backup, because RMAN will only remove saved ARCHIVELOGS.

• Duplicate the database and incremental backups

  Hello
  
  I reviewing options to maintain a test server that is "relatively" updated compared to the production server.
  This is my first contact with RMAN and I went through the books, but as I have not had a chance to play with it I could have missed something.
  
  It is an Oracle devoted to a Redhat Enterprise Linux (not sure of the complete version number) 11.2.
  
  The test server must be writable and must be synchronized with the server in production about once or twice a month. Due to the size of the database (~ 600 GB) we are studying solutions that could make using incremental backups that are already taken on the production database.
  
  While launching the test using RMAN DUPLICATE server seems to be honest, I'm not sure how the "sync" can be done as effectively as possible - especially because we are changing the data on the test server.
  
  After the RMAN BACK command description, is not clear to me if this could serve to 'recover' the database of test based on the incremental backups to the 'current state' of the production database, even if the test database has been changed. After reading a few posts here, it's not seems to be the case.
  
  A restore point would make such a possible incremental restore? Creating a (name?) point of restoration immediately after duplication, and once the tests are finished making back to the restore point and then apply the incremental backups that have accumulated since then.
  
  
  Another of the options seems to be to create a database of the previous day. Then when running the tests, we turn to the backup database in one instantaneous standby database open read/write and run tests. Once we have finished, we he switch back to a physical standby. This switchback to rewind the changes and recovery logs accumulated are applied as "incremental" catching up with production - which is basically what we want.
  
  Is there another solution to this? Or use a watch of the snapshot, the most effective solution? If possible, we would like to avoid transferring the 600GB whenever we want to re - synchronize the database to test.
  
  Thanks in advance

  Hi Tomas. I think you're right. Ensures the most effective solution in your situation of snapshot.

• Merger of the RMAN incremental backups

  Hi all
  
  I have a confusion.
  
  Sunday I L0 scheduled backup (backup as compressed).
  Then next 6 days (MON - sat) I incremental backup Level1 (differential).
  
  So let's assume that if I need to restore the Thursday, I need Sunday L0 and L1 of (MON, TUE, WED).
  
  Is it possible to merge L0 and L1 (until WEDNESDAY).
  
  Please specify.
  
  Thanks in advance.
  
  Kind regards
  Bikram

  As long as you use differential incremental backups, you need all of them between the last level 0 backup and recovery at the time point. It is exactly the concept of cumulative incremental backups to change this behavior. In the case of cumulative backups you would only need the full backup and the incremental backup from Wednesday.

• X100e backup/restore

  Hi, I just bought a x100e with preinstalled Windows 7 and wonder how to make a system backup/restore correctly. I need to install Ubuntu in a few days and create/edit a few partitions that exist (I guess that this will replace mbr) and I want to be able to restore the initial state of the system. So, what's the best "workflow" to save/restore, System State or reset to factory settings x100e (witch is probably most interesting for me) in my dulling?

  Hi and welcome to the forum!

  You can create discs of recovery on a USB drive or burn it to DVD by attaching an external optical drive, old method to see this:- http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/Creating-x100e-recovery-media-on-USB-stick/ta-...

  With recovery discs, you can restore your system to factory settings any time you want.

  This before installing Linux, otherwise you will not be able to once you have installed Ubuntu.

  I hope this helps.

• EM12c create non-cumulative incremental backups (level 1) against target DB

  It is not available? It seems that we can create only cumulative backups RMAN incremental by Cloud 12 c (it's against a 11 GR 2 DB). No cumulative incremental are no longer supported?

  When planning a backup via the wizard, the last step shows the RMAN script, the wizard has generated for you. Have you tried clicking "Edit Script RMAN" and delete the word "cascade" of the generated script?

  I run backups using scripts stored in the recovery catalog so I do not use the Backup Wizard clicks, but it not lead to a differential incremental backup if you edit the script?

• Restore from a backup and incremental backup

  In a recent catastophe I had to restore my PC to deliverable facotry, and at the same time lost an external hard drive with a good number of my images.  I was able to reload the images that are on my C drive but my catalog has gone, as are all the images that were on an external hard drive.  I would like to do a full backup of Photoshop since the end of May and an incremental backup took about a week before the disaster on a second hard drive.  I guess I have to restore using the first backup completes, then restore using the incremental backup.  Is this correct?

  If I specify that the images are loading on my new external hard drive, keeping the same directory structure images go to the new drive or will restore the original images on the drive C on the C drive and only the pictures stored on the previous external drive go to the new external drive?

  I did not in a while, but I recall, you restore the differential and the software is smart enough to know how to use the differentials and complete properly.

  If you ask the program to restore the external hard drive, that's where all the images go.

• How to set the incremental backup of level 1 to restore on a different database

  Hello

  I have a question what is annoys me all week.

  I have 2 databases. ORCL and ORCL2. ORCL2 is an auxiliary ORCL database. ORCL my database is backup incrementaly Sunday level 0, other days level 1. Now, I would like to update my ORCL2 db every night to be synchronized with the ORCL database. Is this possible? I have Oracle Standard Edition, so I can't use Data guard. If you can help me I would be very thanful. Or if you could send me a link to some textbooks.

  Hello Ivan,.

  You can recover the database duplicate, once created each day with an incremental backup of the target database.

  What you need here is a simple restore to another host without opening the database with resetlogs. RMAN: Restoring a backup RMAN to another node [ID 73974.1]

• RMAN incremental backup continue to make backups "complete"?

  Hello, I am new to RMAN. I used only the full backup by RMAN, and it was OK. Now, due to lack of disk space, I decided to make incremental backups.

  I put 'to recovey retention policy window of 3 days; then made a new backup (by MS) job, looks like:

  $rman_script = ' backup database cumulative device type disk tag '% TAG' extra strength 1;

  backup disc tag '% TAG' type device archivelog all not saved delete all entries;

  But, always visible, size of the backup is the same all the time as a full backup? Where is my mistake?

  There is a Note of support Oracle ' size of level 1 or level 1 cumulative backup greater than level 0 backups [ID 1534691.1].

  which applies if you use the DUNGEON and change the tag.

  I note that you change the tag every day, but do not use the clause to KEEP this note should not apply.

  Why not explicitly run EXTRA STRENGTH 0 backup once and then monitor subsequent LEVEL 1 backups?

• PSE 3 How do I restore incremental backups

  Need directions to restore a backup of Photoshop elements 3 when there are incremental backups.

  
  

  This seems like it should be in the documentation, but I'm not.  Help docs only seem to explain the restoration of a full backup.

  I did a full backup with 3 PSE and have also made several incremental since.  I'll put it all on an external USB hard drive, with each backup (one complete in a single folder and any incremental Interior fully his case, but in its own subfolder).

  If I had to restore the whole catalogue in the future, should I start by restoring the complete catalogue and then go back and restore each incremental backup on top of what I already have?

  Or do I have to start at the last incremental and restore it first.  And if I did it, PSE automatically restore all previous incremental backups from that point AND the initial full backup?  Or I have to go back and restore those manually?

  Thanks for your help.

  Terry

  You start from the last incremental backup and backward for the full backup.

  PSE will ask you for each disk or each folder if you use an external hard drive.

• Slow windows Server2008 no incremental backup?

  Hi I am trying to get a Windows 2008 R2 server backup to work at an acceptable level.

  Functioning as a virtual guest operating system assigned to 4 cores and 10 GB RAM.

  I want to save my 155 GB of files on a connected USB drive.

  I plan to run a backup, and it takes about 10 hours to complete!

  When the next calendar ran I expected to back up only the files that have changed...

  However, it seems to run a full backup once more as her about 10 hours to complete...

  does not the incremental backups or something?

  I tried to change the performance setting that indicates that it would be only for backup files that have been changed...

  has not made a difference.

  The Task Manager does not display to the test server...

  any ideas?

• Incremental backup policy

  Hi experts,

  In my organization, we have 4 TB size of database. If we take a complete backup of it, will it take huge time. While we do intend to follow an incremental backup of this jet of RMAN database, my question is, what kind of policy of incremental backup, we follow. I am new to an incremental backup. Yet, I was followed political only full backup.

  (1) we must / should follow political not backup incremental cumulative GOLD diffrential.

  (2) who is stupid or why (cumulative backup incremental GOLD diffrential)

  (3) how to track level in both cases...

  as = > Sunday M T W T F S Sunday

  0 2 2 1 2 2 2 0

  Reg,

  Thomas

  I would prefer cumulative incremental but if the daily a cumulative incremental size is large, you could make an additional bonus.  The disadvantages of additional premium are

  (a) If you lose an additional intermediate differential, you cannot restore the database past the point (unless you have backups, archivelog separated through all database backups)

  (b) it may take more time to restore and recover using additional bonus you would need to restore and apply backups more

  See http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmcncpt.htm#BRADV109

  Note: Level 2 is is more documented.  Level 2 backups are actually incremental differential.
