large blocks help keep the tape moving.. every start/stop introduces either a long delay to stop / roll back a little &amp;&nbsp;start again. &nbsp; (stop is breaking , start is accelerating).<br />
Too large blocks may introduce rewrites due to badspots on tapes if quality is questionable. &nbsp; the start/stop will also occurr en reading a tape back so most probably fairly large blocks are best.<br />
(and not too old tapes help as well).

In my experience too large a block can result in issues down the road. &nbsp;Long blocks means longer times for retries. &nbsp;So down the road if you need to red the data back, it could be problematic. &nbsp;As the tape ages, it losses some flex and &nbsp;can experience more flutter. &nbsp;Although still readable, &nbsp;longer blocks can expose two issues. &nbsp;One they may get more initial read errors than smaller blocks and two it will take more time to reverse and retry those blocks. &nbsp; Use the red riding hood rule here. &nbsp;Not too big and not to small, but someplace in between should be &nbsp;just right.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
