Symptoms

Customer modifies a bunch of media files between backups and complains regarding longtime upload with every backup job. These files may be excluded from caching due to following reasons: a file name extension is skipped by IntelliCache in the configuration file or file size isn’t between 1 MB - 5 GB default cache thresholds.

Steps to resolve

Modify caching skip list

By default, OBRM doesn’t cache files with the following extensions:

.iso, .sys, .cab, .exe, .msi, .dll, .ocx, .bmp, .djvu, .gif, .ico, .jpeg, .jpg, .png, .psd, .264, .3gp, .aac,.aiff, .ape, .asf, .avi, .dat, .flac, .flv, .mkv, .mov, .moov, .movie, .mp21, .mp2v, .mp3, .mpeg, .mpeg4, .m2a, .m2v, .m4a, .m4e, .m4v, .md5, .mp4, .mp4v, .mpg, .mpg2, .mts, .ogm, .ogv, .ogx, .pmf, .mpe, .qt, .rm, .rmd, .rmp, .spf, .sp1, .sp2, .sp3, .sp4, .sp5, .sp6, .sp7, .sp8, .sp9, .spi, .spx, .swf, .ts, .vob, .webm, .wm, .wma, .wmv, .xvid, .7z, .ace, .arc, .arj, .bzip2, .cab, .gzip, .gz, .jar, .rar, .zip, .pdf, .wav, .edb, .log, .bak

To include files with those extensions in caching, or to exclude files with other extensions from caching, follow these steps:

  1. Go to the folder where you installed Online Backup and Recovery Manager, for example C:\Program Files (x86)\Online Backup and Recovery Manager.

  2. Open the SStorage.exe.config file in a text editor.

  3. Find the line beginning with <add key="UA_CacheSkipExtensions" value=.

  4. Add or remove the file name extensions as desired.

Change cached file size

Default minimum size of the file to include in caching is 1 MB (1024 KB).

Default maximum size of the file to include in caching is 5 GB (5242880 KB).

To change these values:

  1. Go to the folder where you installed Online Backup and Recovery Manager, for example C:\Program Files (x86)\Online Backup and Recovery Manager.

  2. Open the SStorage.exe.config file in a text editor.

  3. To change the minimum file size, find the line beginning with <add key="UA_IntelliCacheFloorThresholdInKB" value=, and set a new value.

  4. To change the maximum file size, find the line beginning with <add key="UA_IntelliCacheCeilingThresholdInKB" value=, and set a new value.

MANDATORY: after modifications #1 and #2 Offsite Online Backup Service should be restarted to apply the changes. Starting from OBRM version 6.9, the size range of files which should be processed by IntelliCache can be specified via the client interface only. Navigate to Menu > Advanced options > Caching options.
