    Hello Sahil,

    typically these disks are not some standalone disks used exclusively for a data backup, but located in some kind of disk array. Performing a backup on disk will impose much IO on this disk array. This could even slow down all other activities on the disk array.

    Tape drives still have the best cost/performance ratio, so it definitely makes sense to write data backups directly to tape. Sometimes you see SAP citing "tape is dead" and "disk is the new tape", but surely these SAP guys don't administrate backups or disk arrays.

    Regards,

    Mark

    This is purely depend on environment and scenario.

    If you are taking backup on disk then on tape - actually time line get increase.

    If your database is not large you can take backup directly to tape instead of disk then tape.

    Theres no standard practice, every company has its own backup/data protection policies.

    IMO, make little sense to do a backup to disk just to move it directly to tape afterwards. You can easily do your backups directly to tape asuming you have installed the right "agent" (Check with vendor)

    The procedure is well documented on help.sap.com and by your backup solution vendor.

    Regards, Juan

    One more point to consider:
    I am not familiar with Symantec. But please ask whether you will need an additional Symantec license in case you take backup to tape directly, using Symantec.
    I know for example that with EMC Networker (aka Legato Networker) you would have to pay extra fees.
    Anybody out there knowing about Symantec?

    regards
