Problem with *.au.bak files

[SS Yssel]

Some javascript/style in this post has been disabled (why?)

Our church uses Audacity to record services. We attach a external hard drive (HD) to record to and have set the "Preferences" tab, "Directories" to this HD (d:) After the service we save the Project as "xyz" and wait about a minute and then leave (exit) the program. We do not disconnect the HD before the PC has stopped and do not start the PC before the HD is connected. When we open the HD at home, the xyz_data folder is empty and there are two xyz.aup files, the one of about 1Mb and the other of variing capcities, usually between 60 and 120Mb. The latter file is named xyz.aup.bak. I cannot recover the service from either (I surmise because the xyz_data folder is empty).

 

Can you direct a confused fellow how to avoid this. I should mention that when I leave the program (exit it), I always select "Yes" when asked If I want yo save my alterations.

 

Thank you, I have been using Audacity at home for my own recordings and fin it superb.

Have you set it to the root of the drive (just D:\) or a folder within
the D drive (e.g. D:\auacity-temp\)? You should not use the root of the
drive as a temp directory as audacity requires exclusive use of it's
temporary directory. No other files should be stored within the
temporary directory or they may well be deleted by audacity.

Unless you are short of space on the internal hard drive there is no
particularly good reason to use the external disk for the temporary
directory - it will usually be quicker on the internal hard drive. You
can still save the project to the external drive, and all the data will
be copied over.

If you want to write the recording directly to the external drive, then
the best way to do so is to do File > Save As to save the project to the
external drive before you start recording. All new data will then go
direct to the external drive. After recording, use File > Save to save
the changes (i.e. the recording) to the project. Then exit, and your
project will all be stored on the external drive.

Where are you saving the project to? Do not try to save the project
inside the audacity temporary directory, but rather use another folder
outside the temporary directory. You should then see a progress bar as
the files are moved from the temporary directory to the project
directory (although if they are on the same drive, this will be quite
quick).

Once you have saved the project, you can exit Audacity via File > Quit
and should not get any message about saving changes to the project as
there have been no changes. Do not try to close the track within the
project, as this will delete the audio from the project. Saving at this
point would indeed result in an empty project.

If the folder is indeed empty then there is nothing to recover. The
problem seems to be at the saving end, with an empty project file being
created.

Thank you for your prompt reply, I really appreciate it. I did indeed create
the audacity-temp file on drive D: I need to transport D: to my home to edit
and burn CD's, which is wy we use the external HD.
I will work through your recommendations.

Thank you again.

I think a lot will depend on the connection between the computer you are
making the recording on and the external drive, which needs to be fast
enough for the recording to be captured properly without glitches. If it is a
Firewire connection, or USB 2.0 and you are connecting into a spare USB
port (not a hub) then it should be satisfactory. If you only have a USB 1.1
connection then it probably won't be fast enough, and you will have to
set the temporary directory to C:\audacity_1_2_temp  (or to some folder
inside C:\), and record to that directory then File > Save Project and choose
a location on D:\ to save the Project to. If you have to record to C:\ then
you would not File > Save Project As.. before starting the recording, as you
would then have to transfer the .aup file and _data folder manually from
the C drive to the D drive.

If you can record to the D drive without glitches then it probably would be
best to do as Richard said i.e. use File > Save Project As.. to create a Project
on the D drive before you start recording, then when the recording is over,
use File > Save Project  (not Save Project As..) to save the recorded data
to the Project. When editing your Project at home, always open the .aup file,
not the .aup.bak file.

In case you ever forget to save a Project before you begin recording, make
sure now if you do record to the external drive, that the Audacity temporary
directory is set to "D:\audacity_1_2_temp" and not to root D:\

If you must use the D drive to record to but it is not fast enough, then use
Audacity 1.3.3 and enable "Always hold all audio data in memory" on the
Directories tab of Preferences. This should enable the recording to be
captured to memory (if it has sufficient) without glitches, at the end of which
the recorded data will be transferred to either your temporary folder or to the
Project's _data folder if you saved a Project before starting recording.
