Beta 14 .ntbk file has an elephant size.

[xTrader1]

I understand you changed something in backup format since Beta 13. However my Beta13 .ntbk file from the past week was approx. 100MB and my today's Beta 14 .ntbk file is approx. 1GB .
I also noticed that the backup in Beta 14 is much quicker.

It's strange, as I didn't add anything except of 1 week tick data on 6 currency pairs.

So ??? Has it something to do with a data compression ?

I'm backing up everything, incl. data and market replay.

xTrader1,

B13 would try to compress data as it backed it up. B14 is much faster in backing up by not compressing this data. Which is also why your sizes may be larger since it is just a copy of your data directory now.

Exactly that's what I thought and this is a reason I ask you to leave us a choice whether I want to backup quickly or with a compression. 1GB files will be clogging my disk very quickly and I'm performing non-incremental backup every week until there will be here a stable NT7 release.

I'm sure, an internal compression module continues to be a part of NT7, nobody didn't throw it out, just disabled.
