I own Yellow system with 512MB SSD. Sometimes I like to review data way into history and have set to retain last 3 months in database. Database size has grown to 10GB and it takes quite a time for backup to finish - graphs freeze during backups. I opened Glances and noticed that only one CPU core out of 4 is used which seems very odd nowdays. Unfortunately it seems there is also very high compression ratio set which further delays backup finish time and widens window of backup failure. I use Samba Backup addon to move completed backups to another system:
[23-03-05 21:48:51] INFO: Backup running ... [23-03-05 21:48:52] INFO: Creating backup "Samba Backup 2023-03-05 21:48" [23-03-05 23:26:55] INFO: Copying backup a52e65ef (Samba_Backup_2023_03_05_21_48.tar) to share [23-03-05 23:27:41] INFO: Deleting 29f42767 (Samba Backup 2023-03-02 21:48) local [23-03-05 23:27:42] INFO: Deleting Samba_Backup_2023_01_22_21_48.tar on share [23-03-05 23:27:54] INFO: Backup finished
Please give user a possibility to choose compression parameters for backups.
