I'm guessing/betting the NFS mounts are configured as a separate filespace and node, right?<br />
<br />
How long is the NFS mount path? &nbsp;if over 255 characters that could cause issues with 5.5. &nbsp;what does the dsmsched.log file show?<br />

Hi, <br />
I have a question regarding data type compares between NDMP and NFS.<br />
We are running TSM 5.5 and backing up an EMC Isilon IQ, using a Backup Accelerator.<br />
&nbsp;<br />
Originally this was configured to perform backups over NDMP, however only &quot;full&quot; backups are performed, and never a differential.<br />
I thought it may be worthwhile to mount the NFS shares and perform incremental backups on these mounts. This was to be tested on a share by share basis.<br />
<br />
After many hours the backup completed over NFS. There were over 15 million objects inspected, but only 1 million backed up. This was the &quot;first&quot; backup over NFS of these shares so it should of backed up 15 million objects.<br />
Is TSM perhaps seeing our existing NDMP backups and comparing objects against them?<br />
<br />
Any suggestions as to an optimal way of backing up an Isilon using TSM?<br />
<br />
Thanks

Hi, 
I have a question regarding data type compares between NDMP and NFS.
We are running TSM 5.5 and backing up an EMC Isilon IQ, using a Backup Accelerator.
 
Originally this was configured to perform backups over NDMP, however only "full" backups are performed, and never a differential.
I thought it may be worthwhile to mount the NFS shares and perform incremental backups on these mounts. This was to be tested on a share by share basis.

After many hours the backup completed over NFS. There were over 15 million objects inspected, but only 1 million backed up. This was the "first" backup over NFS of these shares so it should of backed up 15 million objects.
Is TSM perhaps seeing our existing NDMP backups and comparing objects against them?

Any suggestions as to an optimal way of backing up an Isilon using TSM?

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Storage Software

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.
