Complete Error Stack Trace

2023-03-04 02:01:01.209+0000 ERROR [c.n.b.v.OnlineBackupExecutor] Error performing backup for database neo4j
com.neo4j.backup.v2.BackupExecutionException: Backup of database `neo4j` failed.
Caused by: java.lang.ArithmeticException: integer overflow
	at java.lang.Math.addExact(Math.java:883) ~[?:?]
	at org.apache.commons.compress.utils.ExactMath.add(ExactMath.java:43) ~[commons-compress-1.22.jar:1.22]
	at org.apache.commons.compress.archivers.tar.TarArchiveOutputStream.closeArchiveEntry(TarArchiveOutputStream.java:439) ~[commons-compress-1.22.jar:1.22]

Cause

This is due to a critical error in Apache Commons jar v1.22. Neo4j-admin tool in Neo4j version < 5.5.0 uses this jar file and thus database backup and database dump command fails with the above mentioned error.

Fix

The issue was fixed with Apache Commons jar v1.23 and this jar has been used in Neo4j v5.7.0+. Thus an upgrade to Neo4j v5.7.0 or above will help in resolving the backup issue for database with size greater than 1 TB.
