Hi all, We have scheduled backups for every day to be at 8:00PM in the evening for one server host that has around 300GB in full to be backed up. However, because of the innovative pooling mechanisms, it is clear that the entire 300 GB is not getting backed up daily by backuppc as per our expectations. We have scheduled full backups every alternate day and incremental backup every day.
However, what we are observing is that backups are not being taken every day... This is what is happening as per the status table Backup 0 Start time: 8:00PM Day 1 Backup 1 Start time: 8:03PM Day 2 Backup 2 Start time: 8:01PM Day 4 In between, it is supposed to take a full backup on Day 3 which it has not taken. After going through the code base of Backuppc, we observe that the first task that is done on first wakeup schedule is to do the nightly jobs (pool compression, old backups deletion etc.). Since this is time based backup configuration, the nightly job is done as the first task on that time. Depending on the amount of work that needs to be done, it looks like that the time taken for the nightly jobs task to complete is varying every day. In the case of Day 2, it has taken 3 minutes approximately after which the backup would have started. Hence the backup start time has been noted as 8:03PM. For the next backup, it always seems to check for any modifications during the last 24 hours. If for example, the next days nightly job takes only a minute to complete (8:01PM), then first it will check if any backup has been done for the last 24 hours at 8:01PM itself. In this scenario, it will come out that the backup has been done in the last 24 hours since the last backup time was 8:03PM which is less than 24 hours of the current time. Because of this, it skips this day and goes on to the next day's backup. This is turning out to be an serious issue as this results in a loss of one day's backup completely. Please throw some light on the veracity of our observations and advice on how this issue can be resolved.
