>>Hi ADSM-L'ers,

>>Can anyone recommend a tape drive/library solution for backing up a
>>small office environment using ADSM on NT
>>
>>Daily Incrementals:
>>NT Fileserver:   3GB office documents           (in total)
>>  WinLaptops:   8 x 300MB office documents (in total)
>>   AIX Server:   1 GB    home directory           (in total)
>>keep 3 copies of each file (daily change approx 100MB max per day)
>>
>>From time-to-time I would require archiving up to about 5GB data
>>I have seen a list of supported devices for ADSM NT servers but there
>>are too many !
>>
>>Requirements:
>>Must be supported on a ADSM NT server
>>Must be reliable
>>Must be reasonably priced
>>Must support DRM (eg at least one copypool, occasional DB backups)
>>Requires minimum intervention from users to change tapes
>>
>>If I have 2 standalone drives (say 35GB DLT) can I make copypool backups
>>?
>>Tape reclamation should be OK just drop the thresholds occasionally ?
>>Are there any other gotchas ?
