I rely on NVBackup for my TX and have never had a clue what the difference is between Fast compression and maximum compression. (Don't get me started on lessee/lessor). Which is the more comprehensive, and does it really make a difference?

Also, what does "checksum" do, and should i use it.

Last one. I thought I read somewhere that nvbackup does not back up pictures. Is this true? Will it save the millions of icons on my calendar and bonzai? Thanks all,

Peace,

e

i wont for nothing save for what i have, one desire too many

Fast compression is fast, but less space savvy. If you have a large SD card and do your backups manually, you will want to use this setting. But if you do automated backups in the middle of the night, then you'll want it to compress it as much as possible. As for not backing up pictures, I've never heard it myself, but if it is true, my guess would be because pics are stored in the Builtin directory, and NVBackup backups the RAM (or Palm_DM). So if a software program uses an icon, that should be backed up (because it's not an actual photo), because it is stored in a database. As for Checksums, I used to know what it was, but a wild guess would be if that option is checked, then other .Gzip capable archivers would be able to open the archives, but that is a guess.

thanks. Pix take up so much space, I may just keep them on a separate card, avoiding the backup issue.

You can keep them on the card you use to backup. Because keeping pics in RAM is a waist.

Checksum does no actual compression.



I think these icons are stored as Palm databases and should be backed up. But don't quote me on it.

Icons go to the backup. And they restore perfectly. What won´t go are the pics that you store in the internal storage memory, same for mp3s. It´s not a problem, since you have a card. I store all pics and music in the card, so they are always there.

So has anybody actually been using Maximum compression for their backups? If so do you see any differences in restoring from those sets vs a lower compression?

I've been compressing to "4" basically since the beginning of NVB, but I've switched to a smaller, faster card and wouldn't mind increasing the compression. However, I rely on NVB very heavily as my main backup source and don't want to shoot myself in the foot but swapping security and reliability for a few MBs of space.

I've been using max compression for about 6 months, and it has worked perfectly (and I've done far to many restores). With max compression 1MB of RAM = .4423MB of card space

A bit off topic, but is a bigger card a slower card or (more likely) are there different versions of the same sized cards that are faster?

I just bought a 2 meg card, which is what piques my interest.

It is my understanding from other posts that older 4gb cards were faster than similar newer 4gb cards. AFAIK, the 2gb cards have been faster all along, although I don't know why.

The original Transcend 4gb 150x card was very fast, but apparently the newer ones are not as good.

I too have been using maximum compression for around 6 months. And again, I've been restoring far too often, even to a new TX, without any problems (well that I can remember anyway ).

If I remember my computer programming correctly:

Checksum does an EOR (exclusive OR) on the file and returns a fairly unique result that can be compared with another version to see if they are identical.

It is used primarily for comparing files and seeing if they differ AT ALL. If they do the Checksums for each will generally be radically different from each other, even if the differences of the files are small.
