kaikow Posted June 13, 2003 Report Share Posted June 13, 2003 As a test, I just ran my first backup job with Retrospect. Log is below. I backed up to a file on a USB hard drive (Maxtor 5000LE on Adaptec USBconnect 4000 2.0 card using NTFS, compression not enabled, on Win 2000 Pro SP3). I was surprised to see the Compare take longer (actually, much longer) than the Copy. I've never seen that with any other backup software. I forgot to disable Auto-Protect in Norton Auntie Viris the first few minutes of the copy. Disabling Auto-Protect really sped things up. I used all default settings in Retrospect, so I expect that there was no compression used. 1. What is the performance hit using compression? 2. The USB drives are all NTFS, should I enable NTFS compression? 3. I'll be reading the Retrospect User's Guide this weekend, but I'd like any pointers to ways to improve performance. + Executing Immediate Backup at 6/12/2003 18:20 To Backup Set Backup Set A...
