V2i incremental shows full tree...?

Howdy,
I run V2i Protector desktop making full, then incremental
images.
As I would expect, the incremental images are often quite
small, but...
When I attempt to browse those images, they show the
complete tree, that is, everything that is included in the
full image.
I am perplexed by that...
Can you help me to understand the situation?
Very sincere thanks,
--
Kenneth

| An incremental is based off of a full backup and possibly other
incrementals. When you read it in a browser, you get the entire updated
tree... it makes no sense otherwise since an incremental saves disk blocks
that have changed and not files. That is why if you delete one incremental,
everything after that becomes invalid. The verify tool will quickly tell
you if the incremental is good or not.

| I have an additional question. Does a new full backup ever get created
again? Or are incrementals created ad infinitum? I'm just trying to
understand.
Tks.

| Hmmm... this also seems to mean that versions of particular files would be
lost. No?

| A full backup gets created when:
1) You tell it to... do this by setting a parameter when scheduling or
answering a question when backing up interactively.
2) After your system crashes

| Not sure what you mean... if you mean versions of files created and
overwriteen between incrementals - that's the same behavior from any
backup - even file based backups.

| Then it's not what I want. I need to get prior versions since we often have
to go back and retrieve files from a specific date! Any program suggestions?

| Sounds like you want a CDP (continuous data protection) solution;
expect it to cost you a significant amount of money if you really
need to be able to get back to arbitrary points in time. A cheaper
(but still non-trivial) approproximation is to use snapshots, a la
VSS, to capture regular images of file state.

| Hi Pete,
I think we are miscommunicating... when you open an incremental via the
browser, you get the whole tree as it existed at the time of the
incremental. If you need a previous version, you just open a previous
incremental and it will display the entire tree as it existed at the time of
that incremental. So no versions are lost - an incremental will not
overwrite or cause any data to be lost.

| RE:"So no versions are lost "
Oh wow man! That's what I need. To go back to any point in time. If an
incremental can do that, that increases my choice of backup programs. I
thought that incrementals wiped out and LOST prior versions.
Thanks.
