Backup. Exec 1. 1d - What is an acceptable amount of "soft write errors" for LTO- 2? Originally posted by Fulgan: I suggest you try cleaning the tape drive several time and make sure your tapes are of the correct model and not too old. Reformatting the tape might help as well. The tape drive and tapes are brand new.
The tapes were purchased along with the drive from Dell, and are labeled LTO- 2. The format option is grayed out in BE, but I can do a long erase. I won't be able to experiment with cleaning or alternate tapes until this weekend.
Originally posted by Uberstein: This is odd. I have the exact same issue using BE1. Dat. 72 drive. Thousands (like ~2. GB backup) of Soft Write errors, but rarely any hard errors.
Jobs seem to complete OK, but I've always wondered if all the soft errors were "normal." Sounds like they are not, but perhaps the DAT7. LTO drives? The DAT7.
LTO- 2 had far fewer soft write errors than you are seeing. On year- old tapes that were used once per week with a similar job size, I'm seeing about 2.
And this was just with normal inefficient D2. T backups. quote: I'm starting to wonder if "Terminator Power" (controlled via a jumper on the back of the Dat. The Dat. 72 is the only device (besides the actual SCSI controller itself) on the SCSI chain. My "Dell" DAT7. 2 is configured the same way - term power disabled. With only one device on the chain, you shouldn't have to enable term power.
Originally posted by ksanchez. Try downloading the Dell utilities and run a full drive diagnostic to see if anything comes up. Just use a tape that doesn't hold important data, as the full test does read/writes and will kill any data on it. I found a procedure for running a diagnostic on the drive itself, which I plan to do. Do you have a link to the Dell software utility? I poked around their site but couldn't find anything for download. Update: I just ran a straight file backup of the 1 GB .
BKF files on disk (instead of duplicating the backup). The job completed much faster, but there were still about 4. I'm hoping to see some improvement once the faster scsi scratch disk is in place, but I may just need to learn to live with that number.
