OK if your attories permit it. Some entities are required to keep them
for as long as statute of limitations laws or court orders require. This
is often for 7 years. (My system only goes back one year; were I
required to keep files longer, I would need 7 more tapes or so.)

Think about this problem when someone else was administering a system I
used. A file of mine got truncated to only the first 512 bytes. It was a
C source file and the object file was present and it was also in a
library. So no one noticed the source file was damaged for a year or
more. When someone wanted a change in the file, I found it only had the
first few lines. I requested it be restored from backup. But they had
backups for only a month or so, so it could not be recovered.
Disassembling the binary was N.G. because the symbol table (needed for
any meaningful disassembly) was at the end of the file. Too bad.
