Solved Unable to backup - Error Email Received each day

[Evolute IT]

I had this issue for a few days now, nothing seemed to fix it.

3CX Phone System tried to backup but failed due to the following reason(s):
System.Exception: System.IO.IOException: Entries cannot be created while previously created entries are still open.
  at System.IO.Compression.ZipArchive.AcquireArchiveStream(ZipArchiveEntry entry)
  at System.IO.Compression.ZipArchiveEntry..ctor(ZipArchive archive, String entryName)
  at System.IO.Compression.ZipArchive.DoCreateEntry(String entryName, Nullable`1 compressionLevel)
  at _3cxNetBackupAndRestore._3cxBackup.CreateEntry(String name)
  at _3cxNetBackupAndRestore._3cxBackup.ZipFile(String dst, IFile src)
  at _3cxNetBackupAndRestore.BackupTasks.BaseFilesTask.BackupFiles()

  at _3cxBackupRestoreImpl.BackupRestoreUtils.Backup(IFilesystem filesystem, String instanceId, String cfgPath, String dbConnectionString, BackupConfig options, String fullpathFilename, Boolean sendEmail)
  at BackupRestoreSchedule.BackupJob.Execute(IJobExecutionContext context)

So I tried rebooting, deleting all backups and starting over, I even tried to change the schedule config. Nothing works.

Can someone help me? 3CX v16 on Cloud.

Where are you trying to backup ?
Is there enough free space in folder destination ?

Yeah I got it. The guy who installed Linux created partitions for /var and /usr.

/var is 2.0G. That's why.
