Which backup solution to use?

I didn't see anything here, but only looked a few screens deep, so sorry if this comes up a lot.
I just found out from reading here that I was running BOTH the Windows backup AND the Lenovo R&R backup. Nowhere does the computer warn about this (something that should be fixed, IMO).
I deleted all the R&R backups and recovered almost 60GB of disk space.
Can someone provide a link or an explaination as to which service is "better", or at least a comparison. From reading, it seems it is recommended to only run one of them. I saw one post which said R&R was better at recovering, etc, but I see other posts which says it just fails (for that person)...
I have a 142gb drive (reported size for C Thinkpad T61p purchased in Dec 2007, running Vista Ultimate with SP1
Thanks.

Hi ,
We have Oracle 8i DB running on Windows with Backup using CA client.
We are planning to migrate all backups from CA to Netbackup but since Oracle 8i is no longer supported by Netbackup so we need to use either RMAN or User managed backup .
Can somebody guide,which backup solution to use on Oracle 8i (we will migrate DB to MS-SQL) so this will be temporary solution for DB backup.
1) shutdown IMMEDIATE
2) OS file copy all the files
3) STARTUP

If I need a full rman restore which backups will it use?

Hello,
I have a database 11.1.0.7 with 8TB. Block change tracking is enabled.
At the weekend I take level 0 backup and during the week level 1 cumulative.
For some weeks the level 0 backup is failing, so I only have level 1 cumulative backups taken every week day with a 4 weeks old level 0 backup.
If I need a full rman restore which backups will it use? Will it be the last level 0 backup with the last level 1 cumulative?
I ask this because grid crontrol tells me that the recent level 1 backups input size is smaller than last week level 1 backups and in between I dont have any level 0 sucessfull backups. Shouldn't the input size of level 1 cumulative increase until the next level 0 backup ?
The grid reports:

Validating Backups Before Restoring Them
You can run RESTORE ... VALIDATE to test whether RMAN can restore a specific file or set of files from a backup. RMAN chooses which backups to use.
The database must be mounted or open for this command. You do not have to take datafiles offline when validating the restore of datafiles, because validation of backups of the datafiles only reads the backups and does not affect the production datafiles.
When validating files on disk or tape, RMAN reads all blocks in the backup piece or image copy. RMAN also validates offsite backups. The validation is identical to a real restore operation except that RMAN does not write output files.
You can monitor what RESTORE VALIDATE does.
Make precautions, so you do not damage the production DB!!!

Which backup type to use?

Good day
I need to schedule daily online backups of my SAP Oracle 10 system. The default backup_type for online backups is "online" in DB13.
However, it appears this type of backup is useless in a disaster situation, where I have lost an entire system. I have not been able to get brtools to recognise this backup as a valid backup to restore a system from.
Apparently, the backup_type should be "online_cons" to get a consistent backup from which I can restore. The question then is, what is the function of backup_type online - i.e. under what circumstances can I use this? and, should I rather change table SDBAC so that all my backup_type for online backups is online_cons?
I need to not only ensure that my data is backed up, but also that I can restore it properly.
Thanks
Wilhelm

Hi Wilhelm,
>> Can you point me to a guide how to use brtools to perform a recovery onto a new server if I use method online + redo log backups. (PS. I am performing hourly archive log backups as well).
Check the link, below;
http://help.sap.com/saphelp_nw70/helpdata/en/93/4ffb72309fb04e80ebfefae1b7a96f/content.htm
>> I an DR situation I would have lost my primary server, so I have no control files etc.etc. I need to get that back using brtools. The only way I could find that brtools can restore the control file is performing a database reset - and that I can only do if I have a backup of type online_cons.
You can check the link, below;

Control files
Online redo log files
Offline redo log files
Oracle profiles init<DBSID>.ora and init<DBSID>.dba

Main SAPDBA log reorg<DBSID>.log and the structure log struct<DBSID>.log (if it exists, also the script create_raw_links)
Summary BRBACKUP/BRARCHIVE log
Detailed BRBACKUP/BRARCHIVE log
Creating control file is the easiest part of it.
>> Do I run in any risk if all my backups are of type online_cons? Can I still do point in time recovery? If so what is the point of the "online" backup type?
with the "online_cons" you just save the offline redolog files created during the online backup for the consistent backup. You need to start "Redolog backup" for the newly created offline redofiles, after the backup.

Why to use SQL Server's native backup facilities, not other backup solution?

I've been asked in my company: why to use SQL Server’s native backup facilities? Instead, they currently rely on other backup software, like Backup Exec, BrightStor, or even Microsoft System Center Data Protection Manager. Those solutions let the
company manage all of its backups—including SQL Server—in a single place, whereas SQL Server’s native backup abilities only apply to SQL Server.
So what does SQL Server native backup facility give us more to be forced to use it?

Satish and Pawan ... thanks but, a backup solution is just there. they don't need to pay anything. even though, having a backup solution that backup everything on the server, like files, software.. etc is needed regardless if you have SQL Server databases
or not, and if it does database backup it would be even better and more complete as a backup solution. So sorry your answer is not an enough reason that will force me to leave that complete backup solution and use the SQL Server backup tools specifically to
backup databases.
Olaf ... thanks as well. But I was just counting a number of solutions that i think they are related to backup things. yet I believe that Symantec backup exec does backup for SQL Server database, ain't?! what I understood from the link that you gave me,
that some backup applications (if not all) use SQL Server backup facilities to do database backup, is what I understood correct? if yes then the question will be, is there any situation or reasons that force me to use SQL Server backup tools even if I have
those backup solution (that some of them in the backgroud they are using SQL Server backup facilities)? does SQL Server backup tool give me more capabilities in backing up databases than what I find in backup solutions?
The answer is NO, as of now you get all these features in 3rd party native backups...
So in nutshell Microsoft never forces you to use SQL Servers Native backup -----The only reason why you get native backup featues is since SQL Server is an Enterprise Solution MS provide you all features in-built within the bundle so that you don't have
to purchase any other license (incase you\your company doesn't have one already)

Which backup RMAN recover will use?

Hi All,
Suppose we have RMAN backup of 2 weeks assume that we have taken incremental backup on monday to saturday and we take the full backup on sunday again we take the incremental backup on monday.
If we execute recover command which backup oracle will use? incremental backup which is taken on monday or full backup which is taken on sunday? please help me on this?

FROM RMAN reference http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta044.htm#sthref702:
>
Complete and point-in-time recovery of a database can use both incremental backups and archived logs. If RMAN has a choice between applying an incremental backup or applying redo, then it always chooses the incremental backup. Applying incremental backups is faster and captures NOLOGGING changes. If overlapping levels of incremental backup are available, then RMAN automatically chooses the one covering the longest period of time.
RMAN also applies incremental backups to restored files that were not restored from an incremental backup

Need backup solution with zero user interaction

Good Day.
I'm putting together a external/offsite backup solution for a client that runs OSX10 Server on a Mac Mini.
Their data is on a Promise SAN, and they currently back up via software daily to an externally attached 4TB Drive.
The big problem is that each day, a user comes in and removes "yesterday's" external drive to give it to the courier who stored it offsite, then they plug in the drive for "today's" backup. Neither the user nor the courier has access to log in to the server to unmount the external drive. Many times, this leaves the external drive in a corrupted state and unusable.
I'm not allowed to give the user of the courier access to the server, and attempts to schedule or script the unmounting of the drives have been troublesome.
I'd like to know if there's a solution out there, possibly an external chassis with removable drives or something similar that can be used to allow for easy removal of the drives to offsite storage that would not require an actual unmounting of the drive.
All advice is appreciated.

What software are you currently using to do backups?
Not that it will help, but if you were backing up to an external optical drive e.g. DVD or Blu-Ray then they have a physical eject button which would tidily eject the media, unfortunately hard disks and even hard disk docks do not work the same way.
Something that might help would be if whatever backup solution you used was able to work on a Mac that did not need to be logged in as a user, in other words that ran as a Unix style background process. This would mean that as no user is logged in the Finder would not be active and this would reduce but not eliminate the avenues for corruption.
Again it will probably not help you but a different approach used by many is to backup over a WAN or Internet link to another site, with this approach your backup media is already offsite and you don't need to eject it to transport it. This does of course rely on a decent speed link in both directions so as to both allow backups and restores.
Something else to consider, if you used a separate dedicated Mac for doing the backups rather than a server then you could consider giving the courier access to the backup machine without having to give access to a server. If you use encrypted disk images on the backup drive then even with access to the backup machine it maybe possible to still prevent their access to data on it.

Choosing which backups to "reuse" in Time Machine?

I am using an external 500 Gb hard drive to back up my Macbook via Time Machine.
I just replaced the Macbook's motherboard for the second time (making it the third board for this Macbook, including the original). When I replaced the original board (this was before snowleopard), I created a new backup set on the same hard drive. So there are two sets of backups for my Macbook, one called "mike" (linked to the original motherboard) and another called "mike 2" (linked to the second motherboard).
I now have snowleopard, which allows you to "reuse" previous backups. With the third motherboard installed and the "reuse" option checked, TM tries to backup to "mike". But because I have not been using "mike" since I replaced the first motherboard in 2008, there is a lot to back up. There is not enough room on the hard disk for that. However, if I could get TM to use "mike 2", the most current set (which I've been using since I installed the second motherboard), there would be plenty of room on the hard disk.
How do I tell TM which backup set to use? Alternatively, how do I delete "mike"? I tried deleting it as root, but I get "not allowed" (which I find extremely annoying, btw).

That's correct. You should never change, move, or delete anything in your backups except via TM, as that can hopelessly corrupt them. That's why TM uses special "deny everybody everything" permissions on them.
The problem is, the first set of backups are "abandoned." TM won't delete any of those backups when it needs room for new ones, since it thinks they're for a different Mac.
You have two options, both unattractive:
Manually delete all the backups in the old set, one at a time, per #12 in the Frequently Asked Questions *User Tip,* also at the top of this forum.
Erase the TM drive with Disk Utility and let TM start fresh.

I have a mid2009 MacBook Pro for which I have been using a USB WD HD for Time Machine. I'd like to get a wireless HD and start a new Time Machine backup for this Mac and retire the 5 year old WD drive. Can I start over?

I have a mid2009 MacBook Pro running Mavericks for which I have been using a USB WD HD for Time Machine. I'd like to get a wireless HD and start a new Time Machine backup for this Mac and retire the 5 year old WD drive. Can I start over?

no archive/ backup is perfect, HD clones can be set to make incremental additions, same as time machine however, though they are more time involved in doing so.
See the + and - of all data backup/ archives below and "spread it around".... or the "dont put your eggs all in one basket" philosophy.

Data Storage Platforms; their Drawbacks & Advantages
#1. Time Machine / Time Capsule
Drawbacks:
1. Time Machine is not bootable, if your internal drive fails, you cannot access files or boot from TM directly from the dead computer.
2. Time machine is controlled by complex software, and while you can delve into the TM backup database for specific file(s) extraction, this is not ideal or desirable.
3. Time machine can and does have the potential for many error codes in which data corruption can occur and your important backup files may not be saved correctly, at all, or even damaged. This extra link of failure in placing software between your data and its recovery is a point of risk and failure. A HD clone is not subject to these errors.
4. Time machine mirrors your internal HD, in which cases of data corruption, this corruption can immediately spread to the backup as the two are linked. TM is perpetually connected (or often) to your computer, and corruption spread to corruption, without isolation, which TM lacks (usually), migrating errors or corruption is either automatic or extremely easy to unwittingly do.
5. Time Machine does not keep endless copies of changed or deleted data, and you are often not notified when it deletes them; likewise you may accidently delete files off your computer and this accident is mirrored on TM.
6. Restoring from TM is quite time intensive.
7. TM is a backup and not a data archive, and therefore by definition a low-level security of vital/important data.
8. TM working premise is a “black box” backup of OS, APPS, settings, and vital data that nearly 100% of users never verify until an emergency hits or their computers internal SSD or HD that is corrupt or dead and this is an extremely bad working premise on vital data.
9. Given that data created and stored is growing exponentially, the fact that TM operates as a “store-it-all” backup nexus makes TM inherently incapable to easily backup massive amounts of data, nor is doing so a good idea.
10. TM working premise is a backup of a users system and active working data, and NOT massive amounts of static data, yet most users never take this into consideration, making TM a high-risk locus of data “bloat”.
11. In the case of Time Capsule, wifi data storage is a less than ideal premise given possible wireless data corruption.
12. TM like all HD-based data is subject to ferromagnetic and mechanical failure.
13. *Level-1 security of your vital data.
Advantages:
1. TM is very easy to use either in automatic mode or in 1-click backups.
2. TM is a perfect novice level simplex backup single-layer security save against internal HD failure or corruption.
3. TM can easily provide a seamless no-gap policy of active data that is often not easily capable in HD clones or HD archives (only if the user is lazy is making data saves).
#2. HD archives
Drawbacks:
1. Like all HD-based data is subject to ferromagnetic and mechanical failure.
2. Unless the user ritually copies working active data to HD external archives, then there is a time-gap of potential missing data; as such users must be proactive in archiving data that is being worked on or recently saved or created.
Advantages:
1. Fills the gap left in a week or 2-week-old HD clone, as an example.
2. Simplex no-software data storage that is isolated and autonomous from the computer (in most cases).
3. HD archives are the best idealized storage source for storing huge and multi-terabytes of data.
4. Best-idealized 1st platform redundancy for data protection.
5. *Perfect primary tier and level-2 security of your vital data.
#3. HD clones (see below for full advantages / drawbacks)
Drawbacks:
1. HD clones can be incrementally updated to hourly or daily, however this is time consuming and HD clones are, often, a week or more old, in which case data between today and the most fresh HD clone can and would be lost (however this gap is filled by use of HD archives listed above or by a TM backup).
2. Like all HD-based data is subject to ferromagnetic and mechanical failure.
Advantages:
1. HD clones are the best, quickest way to get back to 100% full operation in mere seconds.
2. Once a HD clone is created, the creation software (Carbon Copy Cloner or SuperDuper) is no longer needed whatsoever, and unlike TM, which requires complex software for its operational transference of data, a HD clone is its own bootable entity.
3. HD clones are unconnected and isolated from recent corruption.
4. HD clones allow a “portable copy” of your computer that you can likewise connect to another same Mac and have all your APPS and data at hand, which is extremely useful.
5. Rather than, as many users do, thinking of a HD clone as a “complimentary backup” to the use of TM, a HD clone is superior to TM both in ease of returning to 100% quickly, and its autonomous nature; while each has its place, TM can and does fill the gap in, say, a 2 week old clone. As an analogy, the HD clone itself is the brick wall of protection, whereas TM can be thought of as the mortar, which will fill any cracks in data on a week, 2-week, or 1-month old HD clone.
6. Best-idealized 2nd platform redundancy for data protection, and 1st level for system restore of your computers internal HD. (Time machine being 2nd level for system restore of the computer’s internal HD).
7. *Level-2 security of your vital data.
HD cloning software options:
1. SuperDuper HD cloning software APP (free)
2. Carbon Copy Cloner APP (will copy the recovery partition as well)
3. Disk utility HD bootable clone.
#4. Online archives
Drawbacks:
1. Subject to server failure or due to non-payment of your hosting account, it can be suspended.
2. Subject, due to lack of security on your part, to being attacked and hacked/erased.
Advantages:
1. In case of house fire, etc. your data is safe.
2. In travels, and propagating files to friends and likewise, a mere link by email is all that is needed and no large media needs to be sent across the net.
3. Online archives are the perfect and best-idealized 3rd platform redundancy for data protection.
4. Supremely useful in data isolation from backups and local archives in being online and offsite for long-distance security in isolation.
5. *Level-1.5 security of your vital data.
#5. DVD professional archival media
Drawbacks:
1. DVD single-layer disks are limited to 4.7Gigabytes of data.
2. DVD media are, given rough handling, prone to scratches and light-degradation if not stored correctly.
Advantages:
1. Archival DVD professional blank media is rated for in excess of 100+ years.
2. DVD is not subject to mechanical breakdown.
3. DVD archival media is not subject to ferromagnetic degradation.
4. DVD archival media correctly sleeved and stored is currently a supreme storage method of archiving vital data.
5. DVD media is once written and therefore free of data corruption if the write is correct.
6. DVD media is the perfect ideal for “freezing” and isolating old copies of data for reference in case newer generations of data become corrupted and an older copy is needed to revert to.
7. Best-idealized 4th platform redundancy for data protection.
8. *Level-3 (highest) security of your vital data.
[*Level-4 data security under development as once-written metallic plates and synthetic sapphire and likewise ultra-long-term data storage]
#6. Cloud based storage
Drawbacks:
1. Cloud storage can only be quasi-possessed.
2. No genuine true security and privacy of data.
3. Should never be considered for vital data storage or especially long-term.
4. *Level-0 security of your vital data.
Advantages:
1. Quick, easy and cheap storage location for simplex files for transfer to keep on hand and yet off the computer.
2. Easy source for small-file data sharing.

Using time capsule model A1409 and trying to use it as only backup. Already have Verizon wireless router. Do not know which cable port to use in back of time capsule. And also it is asking for password. Have tried all of mine and it will not work.

Want to us my time capsule model A1409 as only backup. 2 TB hard drive.
Already have Verizon wireless router. Do not want to use Time capsule as router, only back up for iMac.
Do not know which cable port to use in back of time capsule to Ethernet port back of my iMac.
And also it is asking for password for the server John Garland's Time Capsule so Time machine can access it..
Have tried all of passwords can think of and none work.
Held the reset button for one second on back of capsule and do not see if anything happened.
What a conundrum.
Appreciate any help to get this working.
Thanks,
John R

I have a 2TB Timecapsule and really only use it for Time Machine backups. But the Wi-Fi side is used to sync my iPad at times.
Mine is wiredup thus;
Eth cable from iMac to modem (not the WAN port should you have one), then eth cable from modem to T/Cap in the WAN port (bottom port with an O sign above it)
I believe when its connected up you may have to set up a wireless network. Follow the instructions to set up Wi-Fi and Network
and then give it a password. The WiFi icon should appear in the menu bar where you can switch it on or off.
Its been sometime since I set it with the help of Apple Techs so I might be a bit rusty.

How to Secure SQL SERVER 2012 Backup without using TDE or any thirdparty backup solution

Hi Experts
Actually I was using backup set password feature for MS SQL SERVER 2008 but it is dropped in new versions (2012 & 2014). Please suggest some options to making the backups secure without using TDE or any third party tools.

Hi khalil_pak,
The WITH PASSWORD feature didn't really encrypt your backup. It just made it difficult for someone to accidentally restore the backup when they were not allowed to. And as other post, the password option is weak and could be broken easily.
The only true way to protect the data is to encrypt the data at the source by encrypting the database with
TDE. Or you can choose to use
cell-level encryption to encrypt sensitive data.
Thanks,

I want a better backup solution.

My current network consists of a 1Tb Time Capsule backing up a 500Gb HDD in an iMac and a 500Gb HDD backing up a MacBook Pro via the wireless network.
I have a 3Tb HDD attached externally to the iMac that I use for large file storage and remote access with my MacBook Pro. It's been a few years since I made the purchase and began using the drive in this way, and I feel like it's time to prepare for the failure of the drive. I've been present for many drive failures of friends and family. I don't take risks of losing my data.
I was curious of the backup solutions you all must have, drive brands that you trust (I'm a WD fan), and if you use RAID 1 or RAID 1 Mirroring.
Thank you.

I use a number of Lacie D2 Quadra drives + OWC Mercury Elite enclosures with WD Caviar Black SATA drives. They have been 100% reliable for many years. (I formerly used Seagate Barracuda drives, but gradually migrated to the Caviar Blacks). In practice, I have 3x backups on separate drives. The drives are only connected during backup operation, otherwise they are disconnected from my Macs, each other and power. I keep one set offsite.
For my more frequent, interim backups, I also use a Lacie D2 Network2 online in my network; I back up email & documents more frequently than other files since they change daily. I use a combination of manual copies via the Finder and automated backups via CarbonCopyCloner depending on what I want to backup at any particular time. I do not use Time Machine or a Time Capsule.
RAID is interesting and useful, but it is not backup. Mirroring only protects you against a single hard drive failure in the Mirror set itself. It does not protect you from software, user or system errors, which are much more frequent than hard drive failures. And in the event the RAID Mirror enclosure itself fails, both drives are likely to be unusable.

Backup solutions for Solaris 10 systems

I am trying to put together a backup solution for a number of SunFire V240 systems running Solaris 10. We do run our backups using NetWorker, along with a couple of high powered back up systems. But this solution I am trying to create is something that can be performed by our first responders, our help desk folks. The systems in question are already in production but we do have days where we can bring them down for maintenance or whatever we need to do. Therefore, I can implement this new solution during the day(s) of maintenance time.
I was looking at using Solaris Volume Manager and its metadata configurations. But I am unsure how to start with files sytems already created. I want to be able to have a backup of the boot disk in the event that the hard drive in which it resides goes down. I want our help desk folks be able to immediately bring the system right back up with little down time during the evening to late hours.
I guess what I am looking for are exact steps to help configure this backup solution with Solaris Volume Manager for our production systems. Can anyone help?

Hey there,
Have a look at this excellent guide. I think that you may find what you need here. If not drop an email back. To begin with you need an extra disk(s) since you will mirror your data. This is sort of a pre-requisite.
Good luck,
Pierre
