Thank you Dave, this nice piece of code one I needed just now.

Re: Get 4D file(Last backup file) v17.4 returning wrong file path

2020-08-25 Thread Dave Nasralla via 4D_Tech 
Just a followup.
Tech support has filed a bug for the issue. It's a command that not
many people use I'm guessing. I've just started using it to move a 4D
Backup to a BackBlaze folder once a week so it can be backed up on the
weekend to the cloud. During the week, we just backup the daily
journal files.

It turns out 4 out of 5 of my systems fail with this command.
My workaround to get the path is a simple routine to read the XML Backup file.
It seems to work fine in v17. Have not tried in v18.

  // 
  // Method: UT_LastBackupFilePath
  // Method Path: UT_LastBackupFilePath
  // Description
  // Work Around for failed 4D Command "Get 4D File(Last backup file)"
  //
  // Parameters
  // 

C_TEXT($0;$PathToLastBackup_vt)

C_BLOB($BackupFileBlob_vx)
C_TEXT($xml_Struct_Ref;$ElementRef_vt)

DOCUMENT TO BLOB(Get 4D file(Backup configuration file);$BackupFileBlob_vx)

$xml_Struct_Ref:=DOM Parse XML variable($BackupFileBlob_vx)
$ElementRef_vt:=DOM Find XML
element($xml_Struct_Ref;"/Preferences4D/Backup/DataBase/LastBackupPath/Item1")

DOM GET XML ELEMENT VALUE($ElementRef_vt;$PathToLastBackup_vt)

$0:=$PathToLastBackup_vt

I'm kind of interested in a straw poll. I'll post it in another thread.

Re: Get 4D file(Last backup file) v17.4 returning wrong file path

2020-08-19 Thread Dave Nasralla via 4D_Tech 
It turns out 3 out of 4 of my systems have this issue. The last backup path
does show up correctly in the backup.xml file in the Preferences folder,
but the command still fails. I’ve opened a case with Tech Support and have
them a sample database. We’ll see what they find out.

Thanks for your help.

in v18 it is backupHistory.json, I think.

Re: Get 4D file(Last backup file) v17.4 returning wrong file path

2020-08-18 Thread Dave Nasralla via 4D_Tech 
Thanks for the advice, Keisuke.

The command seems to work in a blank database (just running it in a
test method after doing a backup), but does not work in my main system
in a test method.
This makes me think something got corrupt. Do you know where the "Last
backup file" path information is stored?

Re: Get 4D file(Last backup file) v17.4 returning wrong file path

2020-08-18 Thread Keisuke Miyako via 4D_Tech

technically you should move your fresh 4BK file after On Backup Shutdown, not 
during,
because 4D updates the backup history json file following the database event,
and a  missing backup file will trigger a runtime error.
one way to avoid this is to start a new process and wait a little before moving 
the backup.

I can't answer your question about Get 4D file + Last backup file
other than to assume that the information is only updated after On Backup 
Shutdown.
