Recomended TAPE backup for OS X Sever

Hi,
I would like to inquire regarding back-up device for OS X Server, My client requirement is a TAPE backup, do you suggest any brand of tape backup and software that works well with OSX server?
Thanks a lot,
val

You need to clarify your needs before you go much further.
There are many tape technologies, including things like DLT, LTO and AIT (amongst others). Each has their own pros and cons, including per-tape capacity, speed, etc.
Knowing the volume of data to backup and how frequently you want to backup is going to be critical in deciding what tape format to take.
For example if you have 1TB of data to backup you don't want to use a tape format that has 20GB per tape - you'll need 50 tapes for a full backup.
The volume of data and frequency also leads to speed. If you need to backup 1GB of data in an hour your options are dramatically different than if you need to backup 1TB of data in an hour. Some tape formats can keep up with the higher throughput, others can't.
Then, of course, there's budget. The larger, faster drives tend to cost more, but they're more capable. But you don't need to buy capabilities that you don't need.
So, you need to answer those questions in order to find the tape technology you want to use. Once you know the technology you can start looking at vendors.

DPM 2012 R2 crashes during tape backup for a specific server

Hi Community,
A customer of ours is experiencing an issue with DPM crashing after a period of time when backing up a large protection group to tape.
Customer is running DPM 2012 R2 URE 5
Upon looking in the DPM Logs, we see the following error, immediately prior to the system crashing.

The server is part of a protection group that is co-located, I am trying the backup not as part of a co-located set to see if this makes any difference.
Tape backups for other servers, which are part of the same co-location group, work fine and it seems to be just this one causing the issue.
I have seen a few other posts on the net referencing "WARNING MediaPool 00000000-0000-0000-0000-000000000000 does not exist." where people have similar issue with DPM crashing out but so far nobody seems to have any answers.
I am debating removing the protection group and trying to 'start from scratch' but wondered if anyone else had any thoughts ?
Thanks in advance,
Ed

Hi,
Open SQL management studio and connect to the instance used by DPM.
Run the following Query against the DPMDB and see if it returns any rows, if so please provide the output.
select MP.mediapoolid, MP.PGSETID from dbo.tbl_MM_MediaPool MP
Join dbo.tbl_IM_ProtectedGroup PG on PG.ProtectedGroupId = MP.MediaPoolId
where PG.MediapoolId is NULL
and MP.PGSetId is not NULL

Steps and Docs - Automated Tape backup for LINUX OS

Hi
Currently we are using ARC7 tape (LTO) backup movement in which the product belong to firm CA for windows. We are not having the license to use it for the LINUX os.
In one of our environment we are planning to set up automated tape backup movement for the LINUX OS. (Database Backups such as RMAN and export) It would be great if you suggest few links or procedural steps to use which tape backups , how to configure, which brand, documents, what all procedural steps etc.
Thanks

How to include another partition in tape backup

Hi
I use a shell script written by my sysadmin to take backup of our oracle system on tape. now i moved some datafiles on another partition and hence want to include that partition also in tape backup.
for fs in $(cat /tmp/dailybkupfs | awk '{print $1}')
do
# For / replace the / with root for log filename
if [[ "$fs" = "/" ]]
then
fn="root"
else
# replace any / in fs name with _ for use in log filename
fn=$(echo $fs | sed 's:/::g')
fi
if umount ${fs}
then
echo "${fs} unmounted successfully" >>/tmp/logs/summary
else
echo "${fs} unmount failed" >>/tmp/logs/summary
fi
if ufsdump 0uf prddb:/dev/rmt/0n ${fs} >${log}.${fn}.${dt} 2>&1
then
echo "Full Backup of ${fs} completed successfully" >> /tmp/logs/summary
else
echo "Full Backup of ${fs} failed" >> /tmp/logs/summary
fi
if mount ${fs}
then
echo "${fs} mounted successfully" >>/tmp/logs/summary
else
echo "${fs} mount failed" >>/tmp/logs/summary
fi
done
echo "Full Backup of all DB file systems Complete" >> /tmp/logs/summary
Also the dailybkupfs file has the following contents->
/u01
/u02
/u03
/u04
/u05
/u06
Now to include /u07 partition for backup, I just need to include the /u07 partition in file dailybkupfs.right?
Thanks
Anmol

I am concerned that the config file resides in /tmp.
That filesystem normally gets cleared if the box reboots.
So as far as I can tell, if your box is rebooted, the backups stop working..

DPM 2012 R2 Crashes after upgrade - Tape Backup

Hello guys,
I have recently upgraded from DPM 2012 SP1 to DPM 2012 R2 Rollup 3 on Windows 2012 R2 (in-place upgrade)
The basic procedure was to backup the DB, uninstall DPM, install DPM 2012 R2, restore the DB. re-sync all the inconsistent replicas and upgrade server agents. When it comes to the offsite tape backup for whatever reason every time the tape backup
commences it fails instantly with the below error and reports "Backup to Tape Failed"
"Event Log shows MSDPM Error ID 945"
It appears to be failing due to a missing stored procedure 'dbo.prc_SMTE_ComputeDailyTrend'. The stored procedure does not exist on other DPM servers. I'm guessing this is something hanging around in the DB from prior to the upgrade but I can't
seem to track it down. Does anyone have any ideas upon how to resolve the issue?
The description for Event ID 945 from source MSDPM cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
Unable to connect to the DPM database because of a general database failure. Make sure that SQL Server is running and that it is configured correctly.

Persistent setting for rman in tape backup

Hi,
When your are going to take tape backup using RMAN utility, how can u control persistent settings with RMAN(show all). I meant how to set retention policy for datafile,controfile backup and archivelog as well.
And if i choose to take incremental backup how these things are changed?? Please help me on these issue as i have some confusion with this.

Can I use tape drive for backup with win 2012 OS & Sybase database?

I have installed enhancement package 6 for SAP ERP 6.0 with OS windows 2012 and database sybase ASE(15.7.050). I am facing problem while taking database backup on tape drive. I want to know how to initialize tape drive in case of sybase DB and is it possible to take back-up on same. I failed to schedule backup from DB13 so now I am doing that activity by command line. So please help me to solve these issues.
Here I am attaching some files related with backup commands that presently I am using. My SAP system ID is DQS.

That output actually looks pretty good, it was dumping to the tape drive, it just ran out of tape because the drive apparently doesn't automatically detect when it is reaching the end.
For the next step, try adding a CAPACITY parameter to your dump command as discussed at these places in the documentation.
Specifying tape capacity for dump commands
Set the Maximum Capacity for a Tape Drive
Your output above shows it was able to dump 87565594 KB before it ran out of tape,
so lets be a little conservative and try
dump database DQS to TAPE1 with capacity = 87000000, init
go
When the dump reaches that point, ASE should prompt you to pop in another new tape
and then issue the sp_volchanged procedure from a second session (it will tell you what parameters to use for sp_volchanged).
Note: once we get the dump working successfully, we can then create a logical dump device that would store the capacity value, and create a full dump configuration so you gain all the new functionality like dump history, etc.

Recovery window for tape backups

Hope someone can answer to my questions.
With RMAN you can maintain the number of tape backups that are needed for recovery purpose through the “delete obsolete recovery window” command. E.g. the command below ensures tape backups be kept for recovery within 31 days:
delete noprompt obsolete recovery window of 31 days device type 'SBT_TAPE';
Q:
1) If I use a disk area as pseudo tape area in my backups (through ORACLE.DISKSBT library parameter), I guess the above "delete noprompt obsolete recovery window" command would work on the pseudo tape area as well?
2) At my site the pseudo tape area is backed up to tape nightly through the system backup job, and the tape backups are kept for about 1 month by the tape system. To save space in the pseudo tape area on disk can I just set a small recovery window in the above DELETE command (say 1 day) , and relies on the actual tape system retention policy for oracle backups? How would this affect oracle’s ability to do recovery?
Thanks

1) I would never use a 'faked' tape as a permanent solution - only to test tape backup scripts - , as it slows down the backup/recovery process. From RMAN's point of view a pseudo tape works like a real tape, so all valid commands apply.
2) When you delete a backup, RMAN forgets it. RMAN is not aware of still available backups in the tape system, you have to recatalog the backups. That means overhead in manual maintenance and a source for possible errors.

Looking for release dates of Apple external hard drive and Tape Backup 40SC

Does anyone know the release date of these two SCSI drives? If you can ballpark it that would help, but please indicate how certain you are.
1. "Apple External Hard Drive", 730MB
Image: http://www.bigkey.com/pic/apple/drives/apple2_gig_external_harddisk.jpg
2. Apple "Tape Backup 40SC"
Image: http://www.borkware.com/rants/stuc-on-you/AppleTapeBackup2.jpg

Re: the Hard Drive.
I have an Apple brochure dated Feb 1989 that offers the Apple hard Drives: 20SC, 40SC, 80SC, and 160SC \[and that's all].
My recollection of the drive you pictured is that it was mildly scandalous because they were not even made by Apple -- they were made by a prominent (in those days) drive reseller with the Apple logo on them.
RE: the tape drive
I bought my first Mac, a Mac II, in late 1987. Apple Unix was soon offered for it, but there was no practical way to issue the software except to buy a Hard Drive 80 with Apple Unix pre-installed. The tape backup unit pictured was available some time later, but was far too expensive to use for issuing software.

Recomend a good tape drive for archving

I'm running out of room on my HDD's. Can anyone recommend a good tape drive for archiving? (preferably external & supports DAT)
Thanks!

er...Recommend .. sorry for the mispelling

My iPhones gives me a message that I don't have enough storage to backup. When I attempt to manage my storage it shows 1 backup for the phone I use and it's 5GB. I have transferred all my photos to my computer hoping it would create storage but no good.

My iPHone tells me I don't have enough iCLoud storage. When I manage my storage from Settings it shows 1 backup for my primary phone and it's 5GB. I understand that is what Apple provides for free and I could upgrade but I don't want to upgrade. I have transferred most all my photos to the computer and I have no music on my device. And this was several weeks ago and I have attempted to backup since hoping it would create a new backup but no good.
I have even went in the backup and turned off Camera Roll since it's the largest but still no good.
If you have any suggestions other than upgrade your storage plan please help.
Thanks

Try deleting the old backup.
Settings>iCloud>Storage & Backup>Manage Storage, tap the device name and on the resulting screen, scroll down and tap on Delete Backup.

The tape drive is likely the constraint. It cannot write fast enough to handle 4 channels streaming datafiles to it.
I would guess that the datafiles are also going over the network to the media manager. You need to check the network throughput for that link as well.

Related to Unused compression in RMAN backup for 10.2.0.4 database

Hi
I recently read through one of the document related to Unused compression in RMAN backup for 10.2.0.4 database. According to this
Unused Block Compression is done, if all of the following conditions apply:
+ The COMPATIBLE initialization parameter is set to 10.2
+ There are currently no guaranteed restore points defined for the database
+ The datafile is locally managed
+ The datafile is being backed up to a backup set as part of a full backup or a level 0 incremental backup
+ The backup set is being created on disk.
I have two queries
1) What is meant by "uaranteed restore points defined for the database"
2) If backup is being directly taken to tape, this feature would not be used
Rgds
Harvinder

1. Normal and Garanteed Restore Points
2. No

How to manually run a Yearly Tape backup of a Volume in DPM?

I can run a manual tape backup by right clicking on the volume and choosing Long term backup, but it only runs the monthly tape backup job.
How can I manually run a Yearly Tape backup job?
I am using DPM 2010.
There must be a way to create a job that uses Yearly backup settings.
Or an alternative is to change the expiry date of the Backup if that is possible.
Thanks,

Although you cannot pick the recovery point date in the past to make a new recovery point from, you can run the DPM Power shell script in this
post to select a recovery goal to make a current backup for. The recovery point date would be that of the latest disk based recovery point for any goal selected.
