>>BE seems similar to DI in that it compresses files into one big file.
BE is a backup system. The other two are file-system level
copy programs. Only superficially the same.
Not to belabor it, BE knows about media (tapes, CDRs, etc),
backup sets, complete and incremental backups, media rotation,
rollbacks/rollforward, and so on. As a general topic,
backup/archive/rotation/restoration is a very complex subject.
DI and (what's the new rage, 2copy?) are file and partition
level backup systems, with (it sounds like) versioning in
2copy.
A big difference. At best they provide only the lowest
levels of what BE does using the Windows file systems
(disk, network, etc).
Not to knock 'em. Just gotta know what you want. For
my purposes, something like 2copy sounds very close
to the starting point I'd use for my own automated backups, if
I ever get to it. |
