 * Hi 🙂
    I have 2 questions:
 * 1- Is there any difference in backup time if I set splitting size 4000 mb in 
   compare to 400 mb? Any difference of pressure to resources?
 * 2- During the backup my website went down, and I saw database error. Hosting 
   told me:
 * it appears that your VPS killed the MYSQL process automatically as it reached
   out of RAM:
 * Feb 6 14:24:25 vps kernel: [1875083.042052] Out of memory: Kill process 11038(
   mysqld) score 96 or sacrifice child
    Feb 6 14:24:25 vps kernel: [1875083.042301]
   Killed process 11038 (mysqld) total-vm:1037552kB, anon-rss:198128kB, file-rss:
   0kB
 * So I couldn’t take backup. Is there any way to solve this?
 * Thanks

 * Finally I could take backup without my server goes down. But after backup, I 
   noticed the zip backups have been removed from updraft folder in wordpress. However
   I set “retain this many scheduled backups” to “1”. So why the have been removed?
 * This is my log file:

 * Hi,
 * Lowering the backup archive split size will mean that less memory and temporary
   disk space is required to process each backup file. The downside is that this
   results in a larger number of files.
    If you are having issues backing up, I 
   would recommend reducing the split size.
 * From the log, it appears that the latest backup completed without any issues.
   
   After each file is successfully uploaded to remote storage, UpdraftPlus deletes
   the local copy by default. This is to reduce the disk space that is taken up.
 * You can change this with the ‘Delete local backup’ option in the expert setting
   section of the Settings tab.
