# Error with database Backup – Memory Limit

 * I tried adding a comment to another’s topic here but it got deleted. I understand
   the forum guidelines but in this case I felt it was helpful information…I’ve 
   been a member here for over 13 years and don’t tack on to someone else’s topic
   unless it makes sense. This time did, in my estimation.
 * Anyway, I am having the exact same problem as the issue here:
 * [https://wordpress.org/support/topic/error-with-database-backup-memory-limit/](https://wordpress.org/support/topic/error-with-database-backup-memory-limit/)
 * The site in question is also on Ionos hosting. I have BackWPup on dozens of sites,
   but just one of those sites is on Ionos and it’s the only site experiencing the
   problem.
 * The issue is directly related to the size of the wp_options table. At this moment
   I am unable to determine whether it’s an issue with the site or with the hosting,
   but with [@fitnsexy](https://wordpress.org/support/users/fitnsexy/) describing
   the exact same issue with the exact same host, I wanted to add a comment. Perhaps
   my information might be helpful.

 * Hi [@matt6303](https://wordpress.org/support/users/matt6303/)
 * did you increase the PHP memory limit?
 * Also, in case the backup database is too large, I would suggest you split the
   database backup into smaller jobs, so for example, one job for just backup `wp_options`
   table, and another one for backup all remains tables.

 * since we haven’t heard back from you, I’m going to mark it as resolved.
   In case
   you’re still having problems, feel free to let us know!

 * Yes, I’m still having problems, but I’m not sure it’s a BWU problem. I have increased
   the PHP memory limit and created a new Job with just the one table and it still
   gives me the same error:
   [01-Apr-2024 02:57:21] ERROR: Allowed memory size of
   170917888 bytes exhausted (tried to allocate 9533984 bytes)For now I’m just running
   two separate jobs and at least getting everything else backed up. It’s only happening
   on one site, which is hosted on a different server than my other BWU sites that
   are still working fine. So it’s likely either site-specific, or host-specific.
   I haven’t given up my investigation but I’m not sure as of now if there’s anything
   more BWU can do. Thank you.

 * can you help me **exclude** all unrelated to WordPress folders, these folders?**
   In backup WordPress install folder**, just keep `wp-admin` `wp-content` and `
   wp-includes`
