I am using the cron functionality to run a backup of 5 of my virtual machines to another local disk. This is done using the backup command’s documented ability to take in more than one VM at a time.
The issue I’m having is, doing it this way, every minute I got an email with the lines:
2018-12-09 18:09:01.736433 INFO PROGRAM_VERSION Vertical Backup 1.2.2
2018-12-09 18:09:02.240558 INFO LICENSE_INFO Trial license expires on 2018-12-29
2018-12-09 18:09:02.243212 ERROR BACKUP_BUSY Another backup job is in progress
I get dozens of these 3 line emails. I’d rather not parallelize the jobs because I’d like one job to finish before the next one starts. Is there a way to get this not to send me 40+ emails but still have serial jobs?
To mitigate it for now, I swapped over to a shell script that executes each VM backup individually. This gets me the serial nature I’m looking for (my backup destination disk is a single large SATA drive, so it gets overwhelmed easily for I/O from the VMs which are hosted off SSDs), but I feel like the vertical backup command shouldn’t try to run all 5 at once.
