That's a great idea. Ill try that out. -----Original Message----- From: Morgan, Joshua [mailto:[EMAIL PROTECTED]] Sent: Wednesday, March 13, 2002 7:32 AM To: NT 2000 Discussions Subject: RE: Backup Strategy with Tons-O-Directories
>From what I've seen it is something Inherent with DLT Drives When you write small files to it the tape has to rewind to stay in the correct place because sending small files you do not get a constant stream of Data. I would suggest using NT/2000 backup to backup these directories, backing them up to a Flat file (one Large File) and then backing it up to tape. You should see your time improve greatly.

I have a server that has about 10,000 folders, each with about 30 very small PDF files. It takes forever to backup. -----Original Message----- From: Ron Jameson [mailto:[EMAIL PROTECTED]] Sent: Wednesday, March 13, 2002 6:39 AM To: NT 2000 Discussions Subject: Backup Strategy with Tons-O-Directories All you backup optimizing experts out there here is a good one - After finally getting a successful backup with a new Overland Ext. LTO drive after dealing with a lot of problems with SCSI Timeouts (ended up switching card to LSI Logic so as not to contend with onboard Adaptec), the time to backup 21g was 7 hours. WOW - Isn't that great?!? Not really. It sucks!!. It only shaved 2 hours from the DAT when in theory (best data stream and file size), it should handle 50g in an hour. Anyway, here is my problem/request for advise. Server Config: 36g Ultra SCSI2, 5400 RPM connected to onboard Adaptec 78xx Asus MB, Twin 450mhz, 1g RAM, Win2k Server Overland Ext. LTO on LSI Logic SCSI Card 22g of data is being backed up 750,000 files (mainly under 10mb and lots of small files) 43,000 directories (yes, that is correct) Veritas Backup Exec 8.6 with server and exchange agents for remote servers. Note: My backup window is 11pm - 7am Network config: 50 power users (accounting firm) on 10/100 3com NICS (2) 48port 3com 10/100 switches 10/100 to the server from switch (needs improvement here including segmentation) The data is only live data - I have not even included the balance of the server data, the email server, terminal server and web server which I have agents installed to do over the wire backups. What are admins doing in a situation like this, to get the best backup speed in the shortest of times? My thoughts are: 1) backup to a drive - then backup the second drive if the file copy does not take too long. May have to put the LTO on a different media server so as not to drag down the data server. Can 2 servers be connected to the same external (via SCSI) storage system? 2) Get some 10k RPM drives and ghost the system to those to replace the 5400 ones (too bad the 15k do not come larger than 36g). 3) I have not tested agent speed on veritas, but does that optimize the data more efficiently than backing up from the local drive? If so, I should move the LTO to another server and backup over the wire. Will have to verify net speed. Should the backup system be moved to its own segment via a Gig port. Hope someone can advise on this nightmare. Getting another LTO is not quite the cost effective option.
