The retention period on the tapes is at least one full day. For the full tape backups it's a week. The incremental backups are one full day as well.
We currently have 5 tapes that we rotate out. One for the weekly full backup and the other four for the daily incremental backup. Part of the reason that it took 4 days was due to restoring the tapes and being limited by the hardware. The tape drive is an external Dell LTO box that only takes one tape at a time. Once restoring the tape to disk, we had to wait for the cataloging of the media to finish. Once that was done, then we could go into the disk media to look if the files were there. The server that performs the backup, is a Dell PowerEdge 2950 with dual Xeon CPU @ 1.60GHz (each) with 5GB of RAM installed. Also the server's only role is to backup. _____________________________ Cameron Cooper Network Administrator | CompTIA A+ Certified Aurico Reports, Inc Phone: 847-890-4021 | Fax: 847-255-1896 [email protected] | www.aurico.com From: Andrew S.

(I'm assuming that the disk backup gets overwritten each week?) Why did it take 4 days to restore the file? Perhaps understanding that will help us provide suggestions.
